1.0 General
1.4 Reference Standards
WOODCO USA offers supplements to general catalogs in order to provide more detailed information about specific equipment.
API Spec 6A
1.1 Purpose
WOODCO USA Top Connectors meet API Spec 6A material requirements including the special Annex K requirement that all Top Connector material meet 75 K strength regardless of working pressure.
WOODCO USA intends this supplement to communicate the design, material, and advantages of WOODCO USA Top Connectors as specified in the “informative” Annex K, of API Spec 6A, 20th Edition.
API Spec 16A 1.5 Material
Annex K specifies that Top Connectors utilize only the following material classes.
1.2 Application Top Connectors using the uppermost collar connection shown in API Spec 6A allow operators and service companies to use interchangeable equipment when making service equipment attachment to the top of well head Christmas Trees. 1.3 Specification
Flange / Body, Collar & Plug. DD-Sour Service a
Carbon or low alloy steel b
EE-Sour Service a
Carbon or low alloy steel b
FF-Sour Service a

1.4 Reference Standards
c
API Spec 6A API Spec 16A Note: API Spec 6A, 20th Edition provides “Informative” information about Top Connectors with a paragraph in Annex K, K.4 warning that specified Top Connector bores will not pass a drift or Backpressure Valve. WOODCO USA Top Connectors will pass both Drifts and Backpressure Valves and satisfy all API specified design requirements. See Section 1.7 of this catalog.
www.woodcousa.com
d
As defined by NACE Standard MR0175/ISO 15156. In compliance with NACE Standard MR-01-75/ISO 15156. CRA required on retained fluid wetted surfaces only; CRA cladding of low allow or stainless steel permitted. CRA as defined in API 6A latest edition. NACE MRO175/ISO 15156 definition of CRA does not apply.

1.6 Service Temperature API Spec 6A Annex K makes no mention of service temperature yet specifies the use of “FKM” (Viton) elastomer seal material. This material has a normal temperature service range of -20°F to 400°F. The following API 6A temperature classifications fall within -20°F to 350°F.
Temperature Classification * P R S T U V X**
Operating Range ( Degrees Fahrenheit [°F] ) Min. Max. -20 to 180 Room Temperature 0 to 140 0 to 180 0 to 250 35 to 250 0 to 350
* PURCHASER MAY COMBINE TEMPERATURE CLASSES e.g. PX, -20 TO 350 °F ** MAY REQUIRE DERATING
Operators may specify lower temperature ratings K (-75°F to 180°F), L (-50°F to 180°F) and N (-50°F to 140°F) using elastomer seals other than FKM.
www.woodcousa.com
1.7 Design WOODCO USA Top Connectors have lowermost connectors meeting API Spec 6A requirements for Flanges, and API Spec 16A requirements for (Clamp) Hub connections. Body diameters between lower and upper connections have maximum allowed diameters. Plugs have spiral retainer rings to keep them connected with nuts and help extract the plug when operators need to enter the well through the Christmas Tree. All WOODCO USA manufactured Top Connectors have API full bores allowing the normal installation of “Back Pressure Valves” through the Christmas Tree. 1.8 Quality WOODCO USA defines “Product Quality” as conformance to specified requirements. We select suppliers on the basis of their ability to provide materials, products and/or services which conform to WOODCO USA and API specifications. All individual units must pass inspections during and after production, and each unit receives a hydrostatic body test. Operators may specify API Spec 6A PSL levels. 1.9 Supplemental Requirements Buyers should clearly define, at the time of order, any requirements which exceed or differ from API Spec 6A.

3.0 Assembly 3.1 Assembly Details and Instructions Figure 4, WOODCO USA Top Connector W/ “Tommy Bars” The WOODCO USA Top Connector follows the API Spec 6A Annex K specifications, dimensions, and design. WOODCO USA has added the feature of “Tommy Bar” holes in the Collar to facilitate turning of the Collar to connect or disconnect the Collar connection.

All WOODCO USA made Top Connectors, have a gall resistant coating on all surfaces. During original assembly, WOODCO USA applies water-resistant grease on the plug and collar. When operators remove the Plug and Collar, WOODCO USA recommends the replacement of this lubricant. Seal rings and backup rings prove easier to install when lightly lubricated with water-resistant grease (applied by hand, brush application of lubricant may cause problems if the brush should lose a bristle that might end up behind or across a seal).
