Kinds of boiler pipe
for low and medium pressure boilers (GB3087-1999) is used for the manufacture of superheated steam pipes, boiling water pipes and locomotive boiler superheated steam pipes, large smoke pipes, small smoke pipes and arch brick pipes for various structures. High-quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless steel tubes.
High-pressure seamless pipe for chemical fertilizer equipment (GB6479-86) is a high-quality carbon structural steel and alloy steel seamless steel pipe suitable for chemical equipment and pipelines with working temperature of -40~400 °C and working pressure of 10~30Ma.
High-pressure boiler seamless pipe (GB5310-1995) is a high-quality carbon steel, alloy steel and stainless steel heat-resistant steel seamless pipe used for the heating surface of water tube boilers for high pressure and above.
How to classify high pressure boiler tubes
Boiler tubes are used in a wide range of applications, mainly for high pressure steam boilers and related piping, and can be classified according to chemical composition, location of use and diameter of pipe.
(1) Classification by chemical composition: carbon structural steel, alloy steel, stainless steel.
(2) According to the classification of steel: divided into pearlitic steel, bainitic steel, martensitic steel, austenitic steel.
(3) Classification according to the part of use: steam pipe outside the furnace and steam pipe in the furnace.
(4) Classification by pipe diameter: divided into large diameter pipe and small diameter pipe.
