ASTM A179 Gr.C Boiler Steel Tube is a kind of boiler tube, the manufacturing method is the same as that of seamless tube, but there are strict requirements for the steel used to manufacture the steel tube. Boiler seamless pipes are often used in high temperature and high pressure conditions, and the pipes will be oxidized and corroded under the action of high temperature flue gas and water vapor. The Steel Pipe is required to have high lasting strength, high oxidation corrosion resistance, and good organizational stability. Boiler seamless pipes are mainly used to manufacture high-pressure steam pipes, main steam pipes and other boiler seamless pipes. According to the temperature of use, it is divided into ordinary boiler tubes and high-pressure boiler tubes.
(1) Manufacturing method:
①The use temperature of seamless pipes for boilers is generally below 450 ℃, and domestic pipes are mainly made of No. 10 and No. 20 carbon steel hot-rolled pipes or cold-drawn pipes.
②Seamless pipes for high pressure boilers are often used in high temperature and high pressure conditions, and the pipes will be oxidized and corroded under the action of high temperature flue gas and water vapor. Steel pipes are required to have high lasting strength, high oxidation corrosion resistance and good organizational stability.
(2) Purpose:
①Universal boiler seamless pipes are mainly used to manufacture water wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes, arch brick pipes, etc.
②Seamless tubes for high-pressure boilers are mainly used to manufacture superheater tubes, reheater tubes, gas guide tubes, main steam tubes, etc. of high-pressure and ultra-high-pressure boilers.

1. The main production process of hot-rolled Seamless Steel Pipe (main inspection process):
Tube blank preparation and inspection→tube blank heating→piercing→tube rolling→steel reheating→fixed (reduced) diameter→heat treatment △→finished tube straightening→finishing→inspection (non-destructive, physical and chemical, Taiwan inspection)→warehousing
2. The main production process of cold-rolled (drawn) Seamless Steel Pipes:
Billet preparation→pickling lubrication→cold rolling (drawing)→heat treatment→straightening→finishing→inspection
Our products aye widely used in water engineering,petrochemical industry,chemical industry,electric power industry,agricultural irrigation,urban construction.
Used for liquid conveying:water supply and drainage.For gas transport:gas,steam,liquefier petroleum gas.
For structural use:as pile pipe,as a bridge;Pipes for wharves,roads and building structures.
