Information

Nipple 2 1/2'' NPT 150 mm A106 Steel is a single-threaded steel nipple designed for high-pressure industrial piping systems. It is manufactured from seamless A106 Grade B pipe and combines a tapered NPT male thread with a weldable plain end, making it suitable for pressure installations.

A106 Grade B Steel

A106 Grade B (also known as ASME SA106 Grade B) is a seamless carbon steel pipe grade widely used in oil and gas refineries, power plants, petrochemical facilities, boilers, and shipbuilding, where pipelines transport high-temperature and high-pressure liquids and gases.

The material is suitable for forming, bending, and welding.

NPT Thread

The NPT tapered thread creates a pressure-tight connection through its tapered profile, often eliminating the need for additional sealing components when installed correctly.
