Manufacturer Prime Quality ERW Seamless Carbon Steel Pipe For Gas Black Pipe Tube Hot Dip Galvanized

Welders and piping experts prefer low carbon steel for things like boiler plates, wire products and seamless tubing and piping uses.

1. The surface of the steel tube is treated with bai anti-embroidery, which is more durable, not more than fast oxidation, and will not form white rust on the steel tube.

2. Comprehensively protect the steel pipe. After heating, each part of the steel pipe is coated with zinc, and the concave and convex parts are protected.

3. It is anticorrosive and wear-resistant, making the steel tube last longer;

Four, since the steel tube has been plated with zinc, which saves the time of painting or painting on the outside, the construction is more convenient;

Five, galvanized steel pipe is three or nine days will not freeze crack, especially suitable for the northern cold and frozen environment.low temperature steel pipe

A/SA-333 Grades allow for cold temperature service to minus 150°F. Material is always provided in the normalized condition at a minimum and Charpy Impact tested to a specific temperature range to assure compliance with the required service temperature.

Low Carbon Steel Contents and Use

Low carbon steel is composed of 0.04 – 0.30 percent carbon. Welders and piping experts prefer low carbon steel for things like boiler plates, wire products and seamless tubing and piping uses. Auto manufacturers typically prefer low carbon steel for vehicle body panels. If the low temperature carbon steel piping is seamless, it can be installed when processing or manufacture piping requires low temperatures to avoid negative impact on this type of piping. One example of use of low temperature carbon steel pipe would be in processes where refrigerants are required to be 50° F. If this is the case, choose ASTM A333 Grade 6 Low Temp Seamless Carbon Steel for pipes transporting refrigerated process materials through a system. This is a simple guide to new installations of low carbon steel pipes with chemical components that include:

. Carbon (max) 0.30
. Manganese at 0.29-1.06
. Phosphorus (max) 0.025
. Sulfur (max) 0.025
