2.Production of Stainless Steel 

1)Manufacturing Facility

Our company is equipped with a number of automatic ring welding machine, semi-automatic wave expansion machine,
bending machine,flaring machine, straightening machine Straightening machine, flat head machine, coil air pressure
machine and other equipment.Ensure customer custom size accurate, docking Neat, 100% pressure test 8kg 15s,
to ensure that customers use pipe without leakage, no porosity.

2)Main Process Requirements:

Our 2B raw materials are mainly from Zhangpu, TiSCO, Baoxin and other famous suppliers. The base materials and
weld seam of the pipe undergo the solid solution treatment integrally. The outer diameter tolerance and inner weld
residual height are strictly controlled to ensure no internal weld traps exist. Each piece is subjected to a 100%
one-by-one pressure detection at 15 kg pressure for 15 seconds.The entire length of the pipe measures 12 meters
with throw light on both inside and outside surfaces, followed by an 18-meter tube pressure test
                                 internal welding seam                                                                        after 30% flaring

3)Argon arc Welding & Plasma Welding


4)Stainless Steel Pipes Online Annealing


Advantages:

1. to reduce the hardness and Improve the Elongation of the Pipe
2. to prevent deformation and weld seam cracking when bending
3. to improve the properties of steel to prepare for later heat treatment

5)Surface Treatment of the Pipes

7) Inspect and Repair the pipe one by one

4.Stainless Steel Tube Packages

We help our customers to Insert the small tube into the large tube, by this way can load as
much as possible pipes into container to save the space and save freight.
