The selfsealing effect means, when the rubber ring is under the fluid pressure, the actual contact pressure on the rubber ring is the sum of the contact pressure of the pre-compressed rubber ring and the new contact

pressure on the rubber ring brought by the fluid pressure. Since the contact pressure is higher than the fluid pressure, so that the joint is well tightened. ——Joint features The joint features simple structure, easy installation and sound sealing performance. The positioning of sealing ring and deflection of joint are taken into consideration during socket structure design. By controlling the insertion depth of the spigot, the joint can have certain axial flexibility. Therefore this type of joint is able to adapt to certain foundation settlement, while long-distance deflection of pipeline can be achieved through its deflection angle θ. Joint deflection installation is shown in Figure 2.
Table 4 Specification Range for Preferred Pressure Class of C-class Pipes
The rubber ring consists of two parts, i.e. the hard rubber and soft rubber. The hard rubber can support and align the pipe joints, and greater thrust is needed during installation.

When the friction between the restrained pipeline and its surrounding soil is greater than the axial stress generated inside the pipe, safe operation of the pipeline can be guaranteed, thus avoiding the set-up of concrete block. ——Application Field In the following conditions, certain length of pipeline with TF-joints could be applied in order to prevent pipeline slippage: 1. Places such as bends, tees, reducers and plugs, etc;
13.6 15.7
that the joint has certain axial stretching and deflection capability.
2. When the pipeline laying slope exceeds 20% (laying overground) or 25% (laying underground); 25
3. When it is uneconomical (such as large-diameter high-pressure pipelines, etc.) or unable to set concrete

——Pipe structure XTJ jacking pipe, as shown in Figure 11, is to make a tubular reinforced concrete protective jacket on the external wall of T-type joint pipe. There’s a jacking flange welded on the spigot of the pipe. During the pipe jacking, the pushing force is evenly passed from the flange with ribbed plate welded at the spigot to the socket, thus ensuring the pushing operation will not cause deformation of the spigot and will not damage the outer protective sleeve; ——Application Field XTJ jacking pipes are applied when the pipeline need to cross obstructions such as roads, railways, rivers and buildings, while trench excavation is not allowed or difficult to prepare on the construction site. XTJ jacking pipe adopts T-type flexible joint. It features sound sealing performance, faster installation,

Data collection —— Collect the topographical information for the area of pipeline burrial, such as the distribution and altitudes of level ground, hills, swamp lands, paddy fields, rivers and beaches, soil types of various regions, transitional areas of two different soils and the terrains with great changes. For example, in the dry area in high altitude, the soil tends to be less aggressive; while in damp areas in low altitude such as ponds, lakes, marshes and peat beds, the soil tends to be more aggressive due to rich humic acid and anaerobes. In the river mouths, lowland, marshes, saline and alkaline lands and other regions along the sea, the aggressivity of soil is probably high.

coating to prolong the service life significantly.
PU coating ductile iron pipe wall
Refining effect During solidification of the coating, rare-earth element can reduce the surface tension of plating solution to increase the crystal core so as to refine the crystalline grains. Such fine eutectic structures can prevent the extension of cracks, even the structures and eliminate bare spots on the surface of coating. This is the important mechanism of rare earth to improve the plasticity and flexibility of the coating, and it is also a special feature of the rare-earth alloy coating.
Anti-corrosion performance Re element can refine microstructure of the coating and reduce its porosity. Meanwhile, it can strengthen Zn-Al alloy coating. Therefore, addition of a small amount of Re element can further improve the anticorrosion performance of Zn-Al alloy coating.

Coating thickness is as specified in Table 12
—— Application fields Zn-Al rare earth alloy coating is an enhanced anti-corrosion solution. It is applicable to the soil with strong aggressivity (i.e. soil with low resistivity, soil influenced by underground water or mixed soil), where PE sleeve is not needed, except the following situations: Acid peat soil; Soil containing garbage, oxide skin and slag, or soil polluted by waste water and industrial effluent; Soil below the sea level and with resistivity less than 500Ω•cm. When applied to the soil types listed above, including the one with stray current, other type of external coatings (such as PU coating) will be recommended.

—— advantages of PU coating With strong mechanical strength, rock impact resistance and soil stress resistance, it can hardly be damaged during handling and installation. Due to good water resistance and zero anti-permeability coefficient, the coating won’t suffer from shellfish erosion when applied in the marine environment for a long time. Due to its good performance in chemical resistance and electric corrosion resistance, ductile iron pipes with PU coating can be applied to complicated soil environment, with prolonged life span.
——Application fields Pipes and fittings with PU coating can be applied to the soil environment with very strong aggressivity and all other types of soil listed below: Humid regions such as harbor and marshes; Hydrous area that is salty and alkaline etc. ——Executive standards: ISO 2531, GB /T 13295, GB/T 24596, BS EN545 and BS EN15189

1.8.2.4 Polyethylene sleeve ——Product description: PE sleeve is the Polyethylene or a mixture of polyethylene and/or ethylene and olefin copolymers sleeve (film) with thickness of 0.2mm that is wrapped on external walls of the pipe on the construction site. It can prevent direct contact between cast iron pipes and the soil. Meanwhile, it also prevents underground moisture from corroding the pipelines. It is used to supplement the basic pipe coating (metalic Znic + HCPE finishing layer) in certain case of highly corrosive soils or in the presence of stray current.

Specification range This kind of anti-corrosion coating is applicable to ductile iron pipes of all sizes. ——Anti-corrosion mechanism The anti-corrosion mechanisms for PE sleeve (film) wrapped outside zinc coating are as following: First of all, PE sleeve can separate the pipelines from corrosive soil and inhibit the generation of electrochemical cell. At the same time, it can also isolate stray current. The PE sleeve is a kind of anti-corrosion method whose performance is achieved through the changing of corrosive environment: it can change the corrosive environment from non-homogeneous soil with strong aggressivity into one that is homogeneous with weak aggressivity. —— Application fields It is suggested to adopt this kind of protective layer for corrosive soil, for example: Soil with low resistivity (with indicator of high aggressivity); Regions with stray current; Regions with high chlorine or sulphur content or active bacteria indicated by the analysis. —— Executive standards: ISO 2531, ISO 8180 and GB /T 13295

through calculation and analysis.
(e.g. soft water), which may attack the materials just like corrosive or aggressive water.
Adopted for the delivery of potable water, the anti-corrosion lining of ductile iron pipes should be nontoxic. This is the most basic requirement for the choice of lining. While adopted for sewerage delivery, the anti-corrosion performance that features microorganism resistance and liquid erosion resistance becomes very important for the lining. And it is those linings with high abrasion resistance and strong acid resistance (especially sulfuric acid resistance) that can provide long-term, reliable protection for the pipes.
1.9.2 Materials in contact with potable water The materials in contact with potable water shall not influence water quality. All above materials adopted by Xinxing for ductile iron pipes have passed the WRC-NSF test of BS6920 of the U.K. and WRAS certification, which proves that such materials can be used for the delivery of portable water. Lining materials for ductile iron pipes provided by Xinxing are listed in Table 15. Table 15 Lining Materials Material

1.9.3 Lining Selection As per the corrosivity of delivered water, anti-corrosion linings of the ductile iron pipes and fittings provided by Xinxing can be divided into three categories:
—— Corrosive water Corrosive water refers to water that corrodes the metal of pipe without lining. Oxygen contained in most of the water can react chemically with iron, which causes its oxidization, generating nodules and tuberculation on internal pipe wall. It will reduce the pipe cross section and significantly cause water head loss increasing over time. This phenomenon often happens in the old pipe without cement mortar lining.
—— Standard lining: Applicable for most raw water and portable water; —— Reinforced anti-corrosion lining: Applicable for water which can attack ordinary cement (soft water, slightly acidic water or highly abrosive water); —— Special lining: Applicable for very special cases or corrosive water (e.g. industrial discharged water) Xinxing will recommend proper internal linings based on water composition analysis. Table 16 summarizes
—— Aggressive water Aggressive water is the water that corrodes calcareous materials (such as cement). Based on chemical

analysis, three results will be caused by the changes in mineral content, PH value and temperature of the water:
Table 16 Types of Lining
Under the given temperature, the water with calcium-carbon balance will neither cause attack nor calciumcarbon deposition. Scale deposition water tends to generate calcium salt deposition (e.g. calcium carbonate) on the internal surface of pipe. Aggressive water can attack the cement mortar containing calcium (e.g. lime, calcium carbonate, or aluminum silicate, etc.) According to the relevant international standards, potable water can be neither corrosive nor aggressive. 32

2.1.1 Preparation of molten iron 2.1.1.1 Molten iron smelting The Fe in the iron ore is reduced in the blast furnace, which will also keep suitable composition of Si, Mn, S, P, and other trace elements in molten iron. With the storage function, the metal mixer can be utilized between the blast furnace and electric furnace for the buffering and thermal insulation, so as to obtain the suitable composition of molten iron. The composition and temperature of molten iron can be adjusted in the electric furnace to achieve suitable values for spheroidisation.
2.1.2.3 Annealing Annealing treatment is a necessary and important procedure during production of ductile iron pipe.

treatment, the mechanical properties of ductile iron pipe can reach the indexes in the Table 1 and comply with ISO 2531:
Inoculation is an important procedure during production of ductile iron, through which graphite in the ductile iron can become more rounded and refined, so that the spheroidizing level can be elevated, and the pipe wall can become denser in structure; in addition, the product prasticity and toughness can be improved too. The metal-stream inoculation is performed along with the centrifugal casting simultaneously. 58

7.1.6 Rubber Flap Check Valve Check valve is mainly used for exit of pipeline pump for water supply and drainage system, petroleum, chemical industry and other industrial fields, aiming to prevent the backflow of transmitted medium. Since the product sealing adopts inclined design, closing time is shorter, can reduce the pressure of water hammer. Valve clack is made through high-temperature pressing of butyronitrile oil resistant rubber and steel plate; washing-out resistance, good sealing performance, simple product structure; maintenance, repair and transportation are convenient.
