Socket Weld Cap Manufacturer in India
Sawariya Metal Industries is a manufacturer, supplier, stockist and exporter of Socket Weld Cap in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, in a wide range of sizes and pressure ratings.
A socket weld cap closes the end of a small-bore pipe permanently with a fillet-welded joint.
Socket weld fittings are forged fittings with a socket bore into which the plain-end pipe is inserted and fillet welded. They are widely used for small-bore process, steam, instrument and hydraulic lines where a strong, leak-tight joint is needed.
Key Features of Socket Weld Cap
Pipe End Closure
Seals the end of a pipe.
Pressure Rated
Rated as per class.
Forged Strength
Dense forged structure for high-pressure duty.
Easy Alignment
Socket design keeps the pipe aligned during welding.

Socket Weld Reducer Insert
A socket weld reducer insert fits into a larger socket fitting to accept a smaller pipe, reducing the line size without a separate reducer.
Socket Weld 90 Degree Elbow
A socket weld 90° elbow makes a right-angle turn in small-bore piping; the pipe is inserted into the socket and fillet welded.
Socket Weld 45 Degree Elbow
A socket weld 45° elbow gives a 45° change of direction in small-bore lines with a strong fillet-welded joint.
Technical Note: Dimensions, pressure ratings and material properties should be verified against the applicable ASME / MSS / DIN / ISO standard, approved drawings, purchase order and Mill Test Certificate (MTC) before final use.
