Product Description

product name:

ASTM A214 Carbon Steel For Boilers,Superheaters,Heat-Exchangers, Condensers Electric

Applications: for Boilers,Superheaters,Heat-Exchangers, Condensers


Size range: O.D.:6-76mm W.T.:0.9-19.0mm L: according to customer requirement

 

Manufacture:

Tubes are made by electric-resistance welding.

 

Surface Condition:

The finished tubes are free of scale., slight amount of oxidation is not considered as scale

 

Heat treatment:

After welding, all tubes are heat treated at a temperature of 1200℉(650℃) or higher and following by cooling in air or in a cooling chamber of a controlled atmosphere furnace.

Cold drawn tubes shall be heat treated after the final cold-draw pass at a temperature of 1200℉(650℃) or higher

QUALITY CONTROL

1~ Incoming Raw Material Inspection
2~ Raw Material Segregation to avoid steel grade mix-up
3~ Heating and Hammering End for Cold Drawing
4~ Cold Drawing and Cold Rolling, on line inspection
5~ Heat Treatment, +A, +SRA, +LC, +N, Q+T
6~ Straightening-Cutting to specified length-Finished Measuring Inspection
7~ Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc
8~ Packing and Stocking.

 

100% of our steel tubes are dimensionally checked
100% of our steel tubes are visually checked to assure they have a perfect surface condition and no surface defects.
100% eddy current test and ultrosonic test to eliminate longitudinal and transversal defects.
