Description

A Threaded Hex Nipple is a pipe fitting that is threaded at both ends and has a hexagonal center. It is typically made from materials such as stainless steel, carbon steel, brass, or other alloys. The thread diameter can vary depending on the requirements of the piping system. The hexagonal part makes it easy to use tools to tighten or loosen during installation or removal.

Applications

• Industrial piping systems: Used to connect pipe sections together in systems for supplying water, gas, oil and other liquids.
• Oil and gas industry: Used in oil and gas pipeline systems.
• Chemical industry: Used in chemical transport systems.
• Food and beverage industry: Used in liquid food and beverage conveying systems.

Standards 

ASME B16.11 is the standard for threaded and socket-weld fittings for high-pressure piping systems. This standard covers requirements for materials, design, dimensions, tolerances, testing, and inspection for pipe fittings.

• Size: Threaded Hex Nipples are manufactured in nominal sizes from 1/2 inch to 4 inches.
• Materials: Carbon steel, alloy steel, stainless steel, brass and other copper alloys
• Working Pressure and Temperature: ASME B16.11 threaded fittings are designed to withstand pressures up to 3000 psi (class 3000) and 6000 psi (class 6000) at working temperatures up to 1000°F (538°C), depending on the material and specific design. Lower pressure classes such as 2000 psi (class 2000) are also available for specific applications.
