X60 pipeline seamless steel pipe is a steel grade specified by the American Petroleum Institute Standard (APL). Its chemical composition: C is less than or equal to 0.28, MN is les

L360 line pipe is the metric equivalent of API 5L X52, with a minimum yield strength of 360 MPa and a minimum tensile strength of 460 MPa. This article explains its chemistry, carb

X52 line pipe: It transports oil, gas or water pumped out of the ground to oil and natural gas industrial enterprises through line pipes.

Tempering is the heat-treatment step that turns quenched steel from hard and brittle into strong and tough. This article explains the three tempering temperature ranges, the micros

The manufacturing route of a steel pipe decides its dimensional accuracy, weld integrity and cost, and API SSAW Large Diameter Spiral Welded Steel Pipe is the process at the centre

API 5L X52 spiral welded pipe is a pipe used to transport fluids such as oil and gas.

3PE and 3PP external coating pipe use a fusion-bonded epoxy primer, a copolymer adhesive and an extruded polyolefin jacket to protect steel line pipe from corrosion. This article e

3PE anti-corrosion steel pipe base materials include seamless steel pipes, spiral steel pipes and straight seam steel pipes.

This article lists the characteristics of fake and shoddy thick-walled seamless pipes for easy identification.

Precision steel pipe is manufactured to machined-part tolerances rather than pipeline tolerances. That single difference - a few hundredths of a millimeter - drives every advantage

A modern heat treatment production line combines a walking-beam furnace, controlled quenching and a tempering furnace to give steel pipe the mechanical properties demanded by API a

Seamless steel pipes are made from steel ingots or solid tube blanks that are perforated into capillary tubes, and then hot rolled, cold rolled or cold drawn.
