zheheng steel Chemical assurance
1. Each lot of raw materials will be tested by spectrometer before
put in storage.
2. 100%PMI the mother pipe to ensure we put right material.
2. 100%PMI the finished pipe again to ensure we produced right
grade
Heat Treatment Assurance
A full-automatic natural gas furnace with 24 meters in length.The
real temperature tolerance could be within 10℃.
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
