Short circuit component

1、Resistance wire contact with steel pipe

1、Resistance wire should be annealed and wound tight

2、Resistance wire on the transition between two core tube

2、Adopting reasonable way of transition

3、Heat-resistant core tube or plate fracture

3、Choose good materials and pay attention not to the fracture

4、Pipe scale drop too much

4、At the end of tube brick was laid

5、Material size control scope

2

Core tube or porcelain tube rupture

1、Heat-resistant porcelain quality is bad

1、Attention to the quality porcelain

2、When welding flame contact porcelain

2、Avoid flame contact porcelain

3、Violent collision or vibration during installation

3、Avoid collision and vibration

4、Use when heated

4、Choose good material, improve the structure

3

Radiant tube cracking

1、Welding material is not good

1、Choose the right welding material

2、Improper operation of welding

2、According to the specification of welding

4

Radiant tube deformation

1、The material of the radiant tube is not good

1、Choose the right material

2、Sling the inappropriate or thermal stress deformation

2、Put it right, if there are any deformation, should take measures in time

3、Horizontal, improper stress

3、The horizontal, should have racks
