Steel lined PTFE pipeline Steel lined PTFE pipeline Steel lined F4 pipeline

Although these types of pipelines have different names, they are all made of the same material, consisting of steel pipes, PTFE pipes, and flanges. First, weld the PTFE pipe to the length required by the customer according to the size, then cut and tighten the lining. After threading the pipe, cut both ends of the pipe mouth neatly and heat it up. Use a corresponding diameter grinding tool to turn it up, and then press it tightly. When flipping in the cold winter, pay attention to immediately flipping after flippingFlatten the pipe mouth with the plate or flange cover and tighten the bolts. Otherwise, the PTFE pipe will shrink due to thermal expansion and contraction, and the flange will be stretched due to shrinkage, which will affect the overall appearance and quality of the pipe. The pipe fittings are all molded and sintered, and can withstand a certain negative pressure.

Steel lined PTFE pipeline Steel lined F4 pipeline is composed of 20 # seamless steel pipe lined with F4 (PTFE), with F4 flanges and standard flanges on both sides for easy installation. The working temperature of the medium for steel lined polytetrafluoroethylene pipe (GSF. F4) is -100 ℃ to 250 ℃. It has the characteristics of corrosion resistance and is suitable for transporting strong acid, strong alkali, and high-temperature media in chemical and pharmaceutical plants.

Steel lined PTFE pipeline Steel lined PTFE pipeline Steel lined F4 pipeline Characteristics:

1. High operating temperature: can meet the operating temperature range of -100 ℃ to 250 ℃;

2. Steel lined PTFE pipeline can withstand high pressure: within the temperature range, it can withstand up to 3Mpa of operating pressure;

3. The overall molding and sintering process lining solves the problem of steel fluorine cold and hot expansion, enabling synchronous expansion and contraction.

4. Standardized size configuration is adopted, especially for the pipes and fittings used in chemical pipelines, which have strong interchangeability, providing great convenience for installation and spare parts.

5. Strong anti-corrosion performance, resistant to various liquids such as strong acids and alkalis.

Manufacturer of PTFE lined steel pipes and production of PTFE lined steel fittings

1. Make corresponding molds according to the diameter of the pipe fittings; The general material is rubber skin;

2. Add polytetrafluoroethylene powder between the pipe fittings and the grinding tool; The powder needs to be filled and compacted;

3. Apply pressure to the sealed pipe fittings and conduct a pressure test according to the design pressure;

4. Remove the mold and place it in a high-temperature electric furnace for calcination, controlling the temperature and sintering time inside the furnace;

5. After removal, perform a 10000 volt high-voltage ignition light test, and if there are no leaks, it is considered qualified;

6. After polishing and finishing, remove rust and paint after cooling.

Scope of application: Industrial sectors such as petroleum, chemical, pharmaceutical, power, pesticide, mining, papermaking, etc.

Process Introduction:

The processing technology of tight lining PTFE with PTFE tube inserted into seamless steel pipe is commonly used for straight pipes; For steel lined PTFE anisotropic parts, tees, and elbows, the process of molding PTFE is uniformly used. The use effect and service life of steel lined PTFE and steel lined PTFE products under two different processes are basically the same, except for the thickness of PTFE. The average thickness of products under tight PTFE lining process is 3-5mm, while the thickness of special-shaped parts under molded PTFE process is 5-10mm, which is related to the inner diameter of pipes and fittings.
