API 5L Grade B Pipe Fittings

API 5L B is the material for seamless and welded pipe cap for gas, oil and water transportation, some pipe fittings are also made by this carbon steel such as pipe nipples.

API 5L pipe fittings usually are applied in high temperature and high pressure applications, they have good mechanical performance, excellent weldability and cost advantages. We offer PLS1 and PLS2 API 5L B pipe fittings for your selection.
