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
