Applications:
1. Instrument
2. Offshore oil
3.Petrochemical
4. Electric appliance industries
Our advantages:
1. We can make it longer
2. No matter how long each coil tube is , there will be no leakag
3.100% inspection ,pressure restistant and more reliable
4. Internal and external clean , reach food grade(Customers shall give prior notice)
5.Complete specifications , products of some specifications in stock
6. Pass FDA test
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.
