]]> Stainless steel hex nipple is a special type of pipe fitting. It has a hexagonal structure, which gives it high strength. The male thread design can be easily connected to pipelines or equipment. Ensuring the tightness and stability,thereby preventing fluid or gas leakage. Therefore, hex nipples are often used in industrial pipelines and precision instruments. Hex nipples are generally produced according to GB/T 14383 and ASME 16.11 production standards, as well as BS3799 standards.

Specification of Stainless Steel Hex Nipple

Types	Equal and Reducing Hex Nipple
Thread	NPT, PT, BSPP, BSPT, PF
Stardard	ASME B16.11 / BS3799 / EN10241

How to Determine Pipe Thread Type

Usually, we use caliper to measure the first, fourth and final full thread. If the measurements are all the same, then it’s parallel. If the measurements decrease in size, then it’s tapered. NPT, NPTF, BSPT, and Metric Tapered are examples of tapered threads.

Common Thread Types of Stainless Steel Hex Nipple

BSPP: British Standard Pipe Parallel

BSPT: British Standard Pipe Tapered

NPT: American National Standard Pipe Tpaer

Dimension of ASME B16.11

ASME B16.11 hex nipple have hexagon shaped section in the middle and male thread on both ends to associate two other pipes or fittings. There are different types such as A105 hex nipple or stainless steel hex nipple.
