Stainless Steel Coiled Tube - JINGNING JINWEN TUBE CO.,LTD

Coiled Stainless Steel Seamless Tube

At present, our company can produce the longest seamless coiled pipe in China, max length 1,000meters per coil, we have gotten ISO9001, Lloyd’s and PED certificate. All tubes are bright annealling which guarantees the surface of tube is smooth.

Regarding the method of inside surface cleaning, we use “water washed by sponge”, as follows:
Insert the sponge into the tubing from one end. Then make sponge move in the tubing by the pressure of water current, which can remove the dust, reacted acid and fragment on the internal surface.

We clean tubes with this method for several times.
After cleaning, then the water in the tube is blown out by air. Then the tubing is put into the drying oven to be dried completely.
Our quality can totally meet customer requirements.
