The biggest advantage of anticorrosion of PTFE lined pipeline

1. High temperature resistance, the highest operating temperature is 260 degrees.

2. Resistant to strong acids and alkalis, with a pH value between 1 and 14.

3. Excellent adhesion, negative pressure can reach 0.09MPa, vacuum effect.

4. Long service life, it can be used for 8 to 10 years under normal conditions, and the warranty period is generally promised to be 1 year.

5. Strong resistance to permeation, various gases such as hydrofluoric acid, chlorine, bromofluoric acid, etc. have good permeation resistance.

Selection requirements for steel pipes and flanges lined with PTFE pipes and pipe fittings:

1. The pipeline adopts national standard steel pipe. Due to process requirements, the effective diameter of the lining pipe is smaller than the nominal diameter of the steel pipe. The designer and user determine the pipe diameter after making the necessary effective flow standards.

2. Flanges can be forged according to user needs according to national standards such as HG, GB, JB, ANSI, JIS, BS, DIN, etc., and can be forged or determined by contract. Due to the sealing surface processing technology, it is recommended to use plate flat welding flanges with neck Flat welding flange. The sealing surface is of flat sealing type. In order to facilitate the installation of the pipeline, the user can provide the user with a flat welding ring movable flange.
