Cold Push vs. Hot Push: How We Manufacture Large-Diameter Stainless Steel Elbows

When specifying stainless steel elbows for high-pressure or corrosive service, one manufacturing detail can significantly affect long-term performance: how the elbow was formed.

RELATED PRODUCTS

90 Degree Elbow

Jinhang Pipeline supplies 90 degree butt weld elbows for industrial piping systems, providing a reliable solution for changing pipeline direction by 90 degrees.

45 Degree Elbow

45 degree elbow is a pipe fitting designed to change the direction of flow by 45 degrees in an industrial piping system. Compared with a 90 degree elbow, it provides a smaller change in direction and can be used where the piping layout requires a gradual directional transition.

180 Degree Elbow

180 degree elbow, also known as a 180° return bend, is a pipe fitting designed to reverse the direction of flow by 180 degrees.

High Pressure Elbows

High-pressure elbows are pipe fittings designed to change the flow direction in piping systems operating under specific pressure and temperature conditions.

Large Diameter Butt Weld Elbow

Large diameter butt weld elbows are pipe fittings used to change the flow direction in large-diameter piping systems. They are widely used in oil and gas transportation, petrochemical processing, power generation, and other industrial piping applications where reliable connections and dimensional accuracy are important.

Flanged Elbow Assembly

A Flanged Elbow Assembly is a prefabricated piping component consisting of an elbow fitted and welded with flanges at both ends in the factory.

Forged Elbow

Forged Elbows are high-strength pipe fittings designed to change the direction of fluid flow in industrial piping systems.

Alloy Elbow

Alloy steel elbows are pipe fittings designed to change flow direction in industrial piping systems.

Stainless Steel Elbow

Stainless Steel Elbows change flow direction in industrial piping systems and are available in 45°, 90° and 180° configurations. Common material grades include ASTM A403 WP304, WP304L, WP316 and WP316L.

Aluminum Elbow

Jinhang Pipeline provides aluminum elbows in 45°, 90° and 180° configurations for different piping layout requirements.

Cross Pipe Fitting

Cross pipe fittings connect four pipe sections at a single junction, allowing flow to be distributed or combined within industrial piping systems.

Socket Elbow

Socket Weld Elbows are forged pipe fittings designed to change flow direction in piping systems through socket-weld connections.
