Boiler tubes of various types:
Seamless tubes of medium and low pressure boilers (GB3087-1999) are used to manufacture superheated steam pipes of various structures, boiling water pipes and superheated steam pipes of locomotive boilers, large smoke pipes, small smoke pipes and arch brick pipes. Hot-rolled and cold-drawn seamless steel tubes of high quality carbon structural steels.


High-pressure seamless pipe (GB6479-86) for chemical fertilizer equipment is a kind of high-quality carbon structural steel and alloy steel seamless pipe. It is suitable for chemical equipment and pipeline with working temperature ranging from - 40 to 400 degrees C and working pressure ranging from 10 to 10 degrees C. 30Ma.


Seamless tube of high pressure boiler (GB5310-1995) is a kind of high quality seamless tube of carbon steel, alloy steel and stainless steel, which is used for heating surface of high pressure and above water pipe boiler.


How to Classify High Pressure Boiler Tubes
Boiler tubes are widely used, mainly for high-pressure steam boilers and related pipes. They can be classified according to chemical composition, place of use and pipe diameter.
(1) Classified by chemical composition: carbon structural steel, alloy steel, stainless steel.
(2) According to the classification of steel, it can be divided into pearlite steel, bainite steel, martensite steel and austenitic steel.
(3) According to the use part, the steam pipe outside the furnace and the steam pipe inside the furnace are classified.
(4) Classified by pipe diameter: large caliber pipe and small caliber pipe.
