Material: 304 304L 321 316 316L 310S 347h 2205 2507 904L etc.

Process size: regular diameters of 8~63mm are available from stock and can be customized according to requirements. According to different applications two processes cold drawing (annealing and pickling for soft industrial tubes) and cold rolling (uniform wall thickness hard and non-annealed bright inside and outside and annealing to become soft industrial tubes) can be used.

Testing: according to the requirements of customers we can do water pressure ultrasonic eddy current testing.

Features:1. Stainless steel boiler tube stainless steel heat exchange tube stainless steel condenser tube with high temperature steam resistance impact corrosion resistance ammonia corrosion   resistance

2. Anti scaling not easy to contaminate and anti-oxidation corrosion 

3. Long service life reduced maintenance time and cost saving

4. It has good pipe installation technology and can be replaced directly. The pipe wall is uniform safe and reliable. The overall thermal conductivity is better than that of copper pipe 

5. It is an ideal heat exchange product for the transformation of old units and the manufacture of new equipment
