What Socket Weld Cap Is Used For
Socket weld cap is a type of pipe fitting, usually liquid or gas-tight which covers the end of a pipe to protect the end. The functions of a cap are similar to a plug. They are mainly used for small pipe diameters.
ASTM A182 socket weld cap is used usually to seal the open end of a pipe. The ASME B16. 11 cap sizes range up to 4 inches in diameter. The caps are used commonly in small size pipes.
Socket weld caps are important components used in plumbing systems. They serve the purpose of sealing off the end of a pipe, preventing leakage and maintaining the integrity of the pipeline. In this guide, we will explore what cap pipe fittings are, how they work, and where they are commonly used.
ASTM A182 Standard
ASTM A182 steel is the standard specification for forged or rolled alloy and stainless-steel pipe flanges, as well as forged fittings and all types of parts and valves for high-temperature service. This standard applies to forged low-alloy steel and stainless-steel pipe parts that are used in pressure systems.
ASTM A182 Socket Weld Cap Specification
Size Range | 1/8" – 4" / DN6 - DN100 |
Pressure Rating | Class 3000lbs, 6000lbs, 9000lbs |
Standard | ASME B16.11, BS3799, EN 10241, MSS SP-83, MSS SP-97 |
Alloy Steel | ASTM A182 F11 / 12 / 5 / 9 / 91 / 92 / 22 |
Stainless Steel | ASTM A182 F304/304L/304H, 316/316L, 321, 310S, 317, 347, 904L，1.4404, 1.4437. |
Duplex Stainless Steel | ASTM A182 F51, F53, F44 |
ressure
There are three types pressure rate for the ASTM A182 socket weld cap, class 3000, 6000 and 9000.
The pressure rate means the pressure the cap can bear, such as class3000 socket weld cap can bear 3000LB pressure, and match with the same or lower pressure pipes and pipe fittings.

Inspection
PMI test
Dimension Test
Visual Test
Hydrostatic test
Flattening Test
We always inspect the goods when delivery. For the socket weld cap, we inspect OD, wall thickness, height.
For the stainless steel fittings, we will also make PMI inspection.
