Tubería de acero galvanizada SOLDADO ENROLLADO EN EL EJÉRCITO inconsútil de la aleación A106 GRB del TUV

Carbon Seamless Steel ASTM BS Black Tube GI Galvanized Steel Pipe A106 GRB Pipe

Carbon steel tubes are made of ingot or solid round steel through perforation into capillary tubes and then made by hot rolling, cold rolling or cold rolling.

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

Hot rolled carbon steel pipe is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipe

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
