Pipe Fittings

Steel tee is a T-shaped pipe fittings that has three branches, normally has two forms with Equal Tee and Reducing Tee (Tee reducer), both are used to divide (combine) the pipelines to adjust the flow rate and change the direction. Steel pipe tee has been be widely used in different industries, according to material types […]

Steel pipe elbows are critical fittings in piping systems, designed to change the direction of fluid flow while maintaining pressure integrity and system efficiency. As one of the most commonly used pipe fittings, elbows are available in a wide range of materials, dimensions, and connection types to meet the diverse needs of industrial and commercial […]

API Coupling refers to the steel couplings that used in connecting casing pipe and tubing. Also known by OCTG coupling, it is usually manufactured in seamless type, material grade same with the pipe body (API 5CT K55/J55, N80, L80, P110 etc), same PSL or providing higher grades than requested. Same heat treatment also applicable, except […]

As we know there are four connecting types for the pipe fittings: Socket weld, butt weld, threaded, and flanged. In terms of steel pipe fittings for pipeline projects, socket weld fittings and butt weld fittings are two popular options. At Octal Steel, socket weld pipe fittings are engineered as essential components for high-pressure piping networks […]

Butt weld fittings are one of the most popular connection types in pipeline systems. It has always been required in massive quantities in different industries, especially for the large diameter pipelines. What is Butt Weld Fittings Butt weld is used to connect pipe or fitting ends by welding. It is a weldable steel pipe fitting […]

ASTM A234 steel pipe fittings are among the most critical components used in welded piping systems, especially in high-temperature and corrosive service environments. These fittings—typically elbows, tees, reducers, and caps—are manufactured from carbon or alloy steel and designed to provide weldable joints that maintain high mechanical integrity under demanding conditions. The material specification ASTM A234 […]
