Pipe End Caps Manufacturers, ASME B16.9 End Caps Manufacturers, Suppliers, Stockist – Buttweld End Caps

  • Metallica is a prominent manufacturer of pipe end cap fittings in India, with butt-welding ends. It is a type of buttweld fitting. Our products are quality certified, and are supplied with relevant test certificates. We specialise in producing custom size stainless steel end caps, carbon steel end caps and alloy steel end caps.
  • A pipe end cap, as its name suggests, is a cap that goes over the end of a pipe, creating a dead end. There are a good number of ways a cap can be applied to the pipe like soldering, glue, or threading depending on the material of the pipe.
  • In addition to buttweld pipe end caps, we also manufacture elbows, tees, bends, reducers, flanges and sockets. Our production range for buttweld end caps is 1/2″-48″. We have been in this line for about 40 years. Our products are exported to many countries and regions in Southeast Asia, the Middle East, Europe and America.
