Boiler Tube Hardness

Boiler tube hardness is one very important factor to determine the quality of high pressure boiler tubes.

First, it must be considered to detect the mechanical properties of hardness high pressure boiler tubes, because it is the relationship between the performance and quality of deformation, punching, cutting and other processing problems. So first of its hardness testing should detect its mechanical properties. Detection methods generally tensile test and hardness test. Tensile test, that is, to the high-pressure boiler tube sample preparation, but also in a tensile testing machine will stretch until the specimen breaks, so you can measure the tensile strength of the high-pressure boiler tubes, yield strength, elongation after fracture and reduction. Tensile tests in the metallic material is often carried out detecting means, is not easy for many hardness test, tensile test must be carried out. There are several hardness test method: like scarification, pressed into law, power law, etc., the material hardness test is one of the easiest tests to compare and tensile test, etc. especially concerned.

Hardness performance requirements

① high hardness and wear resistance;

② high dimensional stability;

③ deformation after heat treatment;

④ In the course of storage or change the size and hardness does not occur.

What is High Pressure Boiler Tube?

 

High pressure boiler tube is one kind of seamless steel pipe. The manufacturing mehod of high pressure boiler tube is the same as other type of seamless steel pipe. However, the steel materials used for high pressure boiler tube has strict requirements. High pressure boiler tube often used in high temeprature and high pressure condition. The pipes is often under the condition of high temperature gas and water vapor, would oxidation and corrosion. Therefore, high pressure boiler tubes require durable steel with high strength, high oxidation resistance, and have good organizational stability. High pressure boiler tube is mainly used to manufacture high and ultra-high pressure boiler superheater tubes, reheater tube, airway, steam pipe etc.

When high pressure boiler seamlss steel tubes use hot rolled manufacturing process, and the outside diameter of the tubes ranges from 22m to 530mm, and the wall thickness of the tubes ranges from 20mm to 70mm. If the manufacturing process is cold drawn, the specification of outside diameter ranges from 10mm to 108mm, wall thickness ranges from 2.0mm to 13.0mm.
