ISO certified manufacturer of low temperature carbon steel pipe fittings attract client with our best quality, service and competitive price.

How much do you know about them? Today, we will introduce to you.

Low Temperature causes harmful impacts on ductility of carbon steels, making steels more brittle and prone to failure. Therefore, we need to use special steel type to handle such situations that is low temp carbon steel, also abridged as LTCS.

Low Temperature Carbon Steel Grade

There are some types and grades for low temperature carbon steel pipe fittings, pipe and flanges.

• ASTM A350 Forged Fittings and Flanges.
• ASTM A420 Butt Weld Fittings.
• A333 Seamless and Welded Pipes

Besides, A106 B often used in low temp pipeline applications. In fact, it is not a LTCS, but its working temperature can be lower according to a specific treatments.

Low Temperature Carbon Steel Pipe Fittings

A420 Carbon Steel Pipe Fittings

A420 is the standard specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Low-Temperature Service. They are chiefly used in low-temperature equipment and especially for welded pressure vessels.

ASTM 420 Butt Weld Fittings Dimensions

Butt Weld Bend provides a strong connection for pipeline, based on the large options of diameter and thickness, you can select freely to meet your needs. You can also choose seamless elbow or welded elbow in consider of your requirements.

LTCS ASTM A420 WPL6 Pipe Fittings

LTCS ASTM A420 WPL6 Pipe Fittings

WPL6 is the most common grade of A420 low temperature carbon steel pipe fittings. They are widely utilized in pressure piping and pressure vessel service. Therefore, our A420 WPL6 butt weld fittings are the preferred choice in the oil and crude petroleum wells as they can progress effortlessly between pipes. They readily allow the passage of toxic liquids.

We also take proper heat treatment for the fittings, generally it is quenching and tempering, so they could be tougher than normalized micro-structures at the same strength level.
