METHOD STATEMENT FOR THE INSTALLATION OF U/G GRP PIPES AND FITTINGS.

1.0 INTRODUCTION This specification covers the requirements to achieve the proper installation of fibreglass piping systems in side DEWA Desalination and Power Station ‘L’ Phase 1(Project reference CE/0081/2009, Inlet Air Chilling for Gas Turbines).

2.0 INSPECTION OF THE PIPE Pipe should be carefully inspected at the unloading site. Each consignment should be visually checked to ensure that the pipes have not been mechanically damaged, externally or internally during handling. -

Internal Control (Look for White spots de-lamination)

-

External Visual Control (Look for damage due to shocks)

-

Control of edges and Joints (Looks for de-lamination or chips due to shock)

A thorough inspection at this stage will avoid any unnecessary work resulting from installation of damaged materials.

3.0 UNLOADING & HANDLING OF PIPES It is essential to maintain control of the pipe during unloading. Guide ropes attached to pipes or package will enable easy manual control when lifting and handling. It should get no shock and not be dropped. This applies especially to sleeves, retainer rings and ends of pipes. Always use pliable straps for lifting the pipe, never use steel cable or chain. Use only, especially for big size pipes, only two support points (see sketch below). Fix both ends to keep control.

METHOD STATEMENT FOR THE INSTALLATION OF U/G GRP PIPES AND FITTINGS.

4.0 STORAGE 4.1 PIPES STORAGE When storing the pipe on ground near the trench, it is necessary that the soil must be levelled and free of rocks and other potentially damaging debris. All the pipes should be choked to prevent rolling in high winds. For long storage, pipe should be placed on supports with side blocks to prevent the pipe from rolling. 5.0 SITE TRANSPORTATION Pipes can be easily transported. Their low weight and their high strength permit an easy and safe transportation. If pipes are transported by fork-lift, it is safe to put on the fork a chassis of 2 mt wide with wood pieces as support, to have more stability and avoid shock on the edges of pipes. 6.0 TRENCH SECTION AND TERMINOLOGY Figure no. 2 illustrates the trench cross section to be used for underground pipes and terminology. It is desirable to keep excavation, pipe installation and back fillings close together to minimise logistic problems and improve area accessibility. Document no. MS/UG-Sp-001, Rev .0

Fig. 2 – Trench – Typical section for GRP Pipes Where an unstable soil condition is encountered which is caused by a water table, the bottom of the trench must be stabilized before laying the pipes. This can usually be accomplished by lowering the water table 120 cm below grade pipe by means of pumps and stabilizing the bottom as already described.

7.0 BACKFILLING MATERIAL According to Fig. no. 2 the following material will be used for GRP pipes installed: Document no. MS/UG-Sp-001, Rev .0

8.0 RECCOMENDATION FOR BEDDING AND COMPACTION

The bed must be over-excavated at each joint location to ensure that the pipe will have a continuous support. However, this area must be properly bedded and backfilled after the joint lamination is completed. Compact by tamping. Tamping shall be done with: -

hand tampers for tamping under the haunches of the pipe;

-

Mechanical tampers used over the entire area of each layer except the most confined zones;

-

Tamping rollers, like rubber-tired or other types, used where space permits;

-

Vibrating compactors. Document no. MS/UG-Sp-001, Rev .0

9.0 LAMINATION IN PREFABRICATION OR AT SITE For Butt & Strap and branch Lamination at site, make reference to the specification ref: MS/Lam-Sp-001, Rev.0 (Specification for Butt & Strap Joints for GRP Pipes and Fittings) 10.0 RIGID CONNECTIONS. When a pipe passes through a concrete wall, a band of rubber has to be wrapped (200 mm wide and 10 mm thick) around the pipe in the area of entry into the concrete structure. In the case of watertight concrete structures a puddle flange shall be laminated on the portion of pipe inserted in the wall. Furthermore it is necessary to achieve following conditions: • Minimum depth of bedding has to be not less than one pipe diameter, but not to exceed the foundation depth of the concrete structure or 1 meter whichever is the lower, and for a length not less than two pipe diameters. • Minimum width of trench has to be not less than three pipe diameters or 1 diameter + 2 meters, whichever is the lower, for a length not less than 3 pipe diameters.

SPECIFICATION FOR BUTT & STRAP JOINTS FOR GRP PIPES AND FITTINGS

1. INTRODUCTION

This Technical Specification describes the various phases of the manufacturing cycle for permanent joints of pipeline elements in glass reinforced plastic (GRP), of plain end type, with reinforcement wrapping obtained with lamination of mat and fiber glass impregnated with resin.

The ways to make butt & strap joints are two, depending on the pipe’s diameter and on the possibility to access the inside of the pipe: • •

Joint without putty and liner restoration from the outside up to the ND600 Joint with putty and liner restoration from inside for diameters ≥ ND600

2. JOINING PROCEDURE

The manufacturing steps, needed to perform a joint, are shown in the following paragraphs. 2.1 CUTTING/ MARKING

Diamond tools (flexible discs) have to be used to cut and grind GRP pipes. Cardboard templates to mark off oblique cuts for elbows or holes of branch connections are available on request. Special equipment for cutting and beveling GRP pipes is available when the job extent requires it. 2.2 TAPERING

Depending on the diameter and on the type of joint, two kinds of tapering are available: •

long tapering, is for joint type without putty and with liner resetting from outside.

•

short tapering (bevel) is for joint type with putty and internal liner resetting.

2.3 PREPARATION

The two pipe ends to be connected must be handled in sequence as follows: 1. Clean thoroughly the two ends of the pipe for a length that must be slightly longer than the length surface to be wrapped. 2. Grind all the surfaces to be laminated (external and eventually internal) with a pneumatic or electric disc grinder, in order to create a rough area. 3. Taper the ends as required by the type of joint, using a grinder. 4. Blow air-jets to remove the dust. 5. Clean again and revive the resin with a suitable solvent (acetone). 6. Let it dry.

2.4 ALIGNMENT

Align the two ends, leaving the required gap, from 3 to 10 mm, between the two plane faces to be jointed. 2.5 LINER RESTORING

The restoration of the liner can be made from the inside of the pipe when the diameter is large enough (ND≥600mm) and when, apart from the size, it is possible to enter into the pipe. It consists in the application of n.2 “C” glass surfacing veils, which must be in contact with the

liquid, and at least n.2 “E” glass mats (375 or 450 g/m²) resin impregnated: A synthetic veil can be used instead of the “C” glass veil.

General Remark: The lamination operations have to start at a time that allows to complete, before the night suspension, at least the liner restoration and a lamination of 5mm thick for pipe diameters up to

800mm or 8 mm for larger diameters. The temperature fall at night could cause thermal shrinkage of the parts and possible ruptures in thin laminates. ¾

Liner Restoration From Outside.

When it is not possible to enter the pipe: 1. The two “C”glass veils and the two “E” glass mats will be applied on the external surface of the ends to be connected, on the tapered area .The “C” glass surfacing veils and “E” glass mats will be as wide as 100 mm. 2. If necessary clean and wash again with acetone the surfaces to be laminated. 3. As soon as the solvent evaporates, apply on the tapered area a first layer of resin and two layers of C glass. 4. Repeat the operation with two layers of mat and resin, hence roll in order to eliminate bubbles and defects of adhesion. 5. After the complete hardening, verify the absence of bubbles, delaminations or defects in the jointing area. 6. .Fill up completely the tapered area with layers of mat and resin, suitably rolling in order to Document no. MS/Lam-Sp-001, Rev .0

SPECIFICATION FOR BUTT & STRAP JOINTS FOR GRP PIPES AND FITTINGS

eliminate air bubbles and to guarantee a correct impregnation. 7. Let polymerize completely (until cooling). Note : Make sure that during the above operation the pipe ends are firmly fixed. ¾

Liner Restoration From Inside

In this case (joint with short taper), the taper must be filled with putty. 1. Check the alignment and the fixing of the pipe ends. 2. Prepare the putty according to the specific prescription. 3. Apply the putty with a putty knife, filling all of the voids.

4. After the filling of the taper, leave the putty to polymerize until cooling and according to the specific requirements, without moving or hitting the pieces. 5. Once the hardening of the putty is completed, grind the putty drippings inside the pipe. Clean with air blow and wash with acetone (If necessary). 6. Apply a first resin coat using a brush, on the internal surface to be laminated. 7. Apply two CSM “E” glass mat, resin impregnated and two “C” glass veils; 8. Apply with a brush the final coat of resin.

3.0 JOINT LAMINATION

a) Apply a first layer of resin, on the ground surface. b) Apply a strip of "E" glass, and impregnate it with resin. c) Eliminate air bubbles with a bubble breaker roll. d) Apply a strip of glass mat cut to measure, and impregnate it with resin. e) Eliminate air bubbles with a bubble breaker roll. The above operations (b-e) will be performed and repeated until the total required thickness is reached. If the total thickness to be reached is very high, it is necessary to perform several layers of a reduced thickness and wait for the hardening of the resin between a layer and the following one. Notice: every single layer must finish with a layer of "E" glass mat. After that the required thickness is achieved and that the hardening is completed, apply with a brush a coat of resin on the external surface of the joint.

3.1 EXECUTION WITH EXTERNAL LINER RESTORATION

Since it is not possible to work inside the pipe, the bevel will be on the outer part and with a long tapering. Two “C” glass veil and two CSM 375 “E” glass mats will be applied on the tapered surfaces. In order to increase the bending radius of the successive laminations, apply over the liner restoration some putty or “E” glass mat strips impregnated of resin. 3.2 EXECUTION WITH INTERNAL LINER RESTORATION

The bevel is made in the inside part of both the main and the branch. The bevel will be filled with putty. The internal reinforcement must terminate with two “E’ Glass mats and two “C” glass veils in contact with the medium. (Internal Liner restoration) For the lamination of the internal and external lamination follow the section 2.6. 4.0 REQUIRED MATERIALS

The following materials are necessary: ƒ

Thermosetting resin.

ƒ

Catalyst, accelerators and different additives.

ƒ

“C” glass stripes, mat and woven roving.

ƒ

Acetone / Similar solvent.

ƒ

Putty and relative catalysts, accelerators and different additives, when required.

5.0 PREPARATION OF RESINS

The types of resin, catalysts, accelerators and additives are indicated in the specific instructions for each project or job. The putty is a resin with thixotropic additives. •

Pour the necessary quantity of resin or putty into a container.

•

Add the necessary quantity of accelerator (unless it is already accelerated)

•

Mix thoroughly the accelerator with resin.

•

Add required quantity of catalyst.

•

Mix thoroughly in order to get a homogeneous compound. Document no. MS/Lam-Sp-001, Rev .0

FOREVER GENERAL CONTRACTING EST.

SPECIFICATION FOR BUTT & STRAP JOINTS FOR GRP PIPES AND FITTINGS

At this point the resin is ready to be applied. It takes from 10 to 30 minute before the hardening begins. Warning: - Never mix the accelerator and the catalyst directly. Explosions may occur or also highly oxidizing phenomena. 6.0 SAFETY PRECAUTIONS

•

Do not seal the catalyzed resin tanks.

•

Do not smoke or use free flames anywhere close the jointing areas, under any circumstances.

•

Safety glasses must be worn while grinding and mixing the resin.

•

Tools must be kept clean by washing them in acetone or in similar solvent.

•

Protective gloves should be used to handle the resins and resin impregnated glass fibers.

•

Closed areas, such as the inside the pipe, or protected areas should be ventilated to avoid an excessive inhalation of resin vapors, and in order to eliminate the possibility of fire by combustible gas.

7.0 FIRST AID

Some procedures of first aid are listed below. a) Contact with eyes. Wash with plenty of water and call for medical aid. b) Contact with skin. Wash with water and soap. c) Excessive inhalation of vapour. Go out in the open air. d) Ingestion. Induce vomiting and call for medical aid. In case of fire use CO2, foam or powder extinguishers must be with in reach in the working area in every moment.
