Pipe cap, a type of pipe fittings, usually covers the end of a tube, and it has the similar function with a plug. Our pipe caps are made of carbon steel, stainless steel and alloy steel, etc. They feature high strength, good toughness, and high resistance to corrosion, and vibration.
BW Steel Cap
BW steel pipe cap is the butt weld type of fittings, connecting methods is to use butt welding. So BW cap ends in beveled or plain.
