Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip after crimping and welding, generally 6 meters. Welded steel pipe production process is simple, high production efficiency, variety specifications, less investment in equipment, but the general strength is lower than seamless steel pipe.

Seamless pipes are derived from solid steel that is in sheet or bar form and is formed into a solid round shape known as “billets” which are then heated and cast over a form such as a piercing rod to create a hollow tube or shell. From: Reliability and Maintainability of In-Service Pipelines.

Galvanized pipes are steel pipes that have been dipped in a protective zinc coating to prevent corrosion and rust. Galvanized piping was commonly installed in homes built before 1960. When it was invented, galvanized pipe was an alternative to lead pipe for water supply lines.

The ST 35 Steel Grade Pipe has minimum 480MPa tensile strength and 315MPa yield strength under normal conditions. The carbon steel has high toughness and is used for high wear and tear applications. There are different shapes of the pipes such as the Carbon Steel DIN 2391 ST35 Round Pipe and other shapes.

Carbon Steel Square Tube is made up of different grades of carbon steels and in square cross sections. These tubes are used in structural engineering to form structures. The Low-carbon Steel Square Tubes are used in applications where high ductility is expected.
