Product Description
1. Ptfe lined steel pipe has the following advantages:

1.1 High temperature resistant {highest applied temperature of 260 degrees.

1.2 Resistance to acid and alkali {pH value between 1 to 14.

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

1.4 Long life { under the generally conditions can be applied for 8 to 10 years, general commitment of warranty period for 1 year.

1.5 Strong resistance to penetration { good resistance to permeability to hydrofluoric acid, chlorine, various gas etc.

2. The requirements of selection for lined with PTFE pipes, pipe fittings, steel pipes, flange.

2.1 The pipeline adopts  the national standard seamless steel pipes. Due to the technological requirements, the effective diameter of lined pipe smaller than nominal diameter.The designers and users must determine the steel pipe size  after testing the necessary  effective flow standard .

2.2 Flange can be customized according to user needs that i HG, GB, JB, ANSI, JIS, BS, DIN national standard. Flange can be forged and also can be determined by the contract. Recommended selection of plate flat welding flange, with flat welding neck flange according to  the sealing surface processing technology. Sealing surface are all planar seal, in order to facilitate pipeline installation, can provide users with flat welding ring and active flange.

3. Ptfe lined steel pipe application range

3.1 Pipes and pipe fittings are tested under water pressure that is 1.5 times as high as the design pressure .

3.2 All the lined with PTFE lining layer after water pressure test has to check the integrity.The leak testing method using electric spark test.

3.3 Application range

3.3.1 Application temperature-20~200ºC

3.3.2 Application pressure ≤2.5Mpa

3.3.3 The allowance negative pressure DN≤250mm is -0.09Mpa,DN>250mm is -0.08Mpa

3.3.4 Can be delivery any concentration of medium such as strong acid, strong alkali, organic solvents, strong oxidizer, toxic, volatile, flammable chemical .

4. Ptfe lined steel pipe pipe propety

4.1 Propety: medium temperature -100ºC~-250ºC

4.2 Medium working pressure,positive pressure: -2.5MPa, Room temperature resistance to negative pressure of 70 kpa

4.3 Corrosion resistance: Ptfe lined steel pipe, In addition to the molten metal lithium, potassium, sodium, chlorine trifluoride, trifluoride oxygen under high temperature, high velocity of liquid fluorine, it can resist almost all chemical medium, including corrosion of nitric acid and aqua regia, It can work under 230 ºC -- 250 ºC temperature for a long time.The steel lined PVDFpipe and the steel pipe lined with other VDF both have the corrosion resistance to the halogen, halogenated hydrocarbon, strong oxidant, boiling acid, alkali and a variety of organic solvents. But not have the great resistance to fuming sulfuric acid, heat concentrated sulfuric acid and nitric acid, above 90 ºC, ketone, ester, amine, and high temperature corrosion of sulfonating agent.
