Information
Nipple 3/4'' NPT 50 mm A106 Steel is a double-threaded steel nipple used to connect two piping components. Plumbers and welders choose ready-made threaded nipples to save installation time, eliminating the need to cut threads directly onto the pipe. This significantly speeds up the assembly of central heating and industrial piping systems.
A steel nipple is also commonly referred to as a spigot, pipe nipple, threaded nipple, threaded pipe, or male × male nipple.
To order a steel nipple, simply specify:
- Required diameter
- Required nipple length
- Required material grade
A106 Steel
A106 Grade B (also known as ASME SA106) is a seamless carbon steel pipe grade widely used in oil and gas refineries, power plants, petrochemical plants, boilers, and shipbuilding, where pipelines transport high-temperature and high-pressure liquids and gases.
Nipple 3/4'' NPT 50 mm A106 Steel is manufactured from steel suitable for bending, forming, and welding.
NPT Thread
The NPT tapered thread forms a pressure-tight joint because the threads are cut on a tapered surface, allowing sealing without additional sealing compounds in many applications.
We also offer steel nipples in other sizes. If you have any questions, please contact us. Call +48 63 261 42 02 or send your enquiry to biuro@polberis.pl. We will prepare a quotation for you.
