Product Description

Various Sizes Steel Lined PTFE Pipe Elbow Medium working temperature -50℃~180℃







PTFE elbow

Purpose: Mainly used to connect two pipes with the same or different nominal diameters to make the pipes turn at a certain angle

Applicable medium: suitable for various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia and various organic acids, strong acids, and strong oxygen Chemicals and other corrosive media


Nominal diameter: DN25-DN2000

Applicable temperature: ≤180℃ (different materials are used for different working conditions)

Applicable pressure: ≤3.0Mpa




Manufacturing process: molding process


The powder molding method lining process (isostatic pressing process) can also be made by winding process, but the shape of the pipe is diverse,Therefore, whether it is production efficiency or molding, it is now more processed by molding technology. Steel lined PTFE elbow can be processed 90° can also be processed into 45°, or according to the angle provided by the customer.


F4 powder molding method lining is a manufacturing process of equal volume, equal pressure and isothermal, which has gone through extruded tubes (loose lining, tight lining),PTFE tape winding, as well as the process evolution of PTFE winding with steel wire and steel mesh, so far F4 powder mold Pressure lining technology is the latest fifth-generation product of F4 lining, which can be used in higher positive and negative pressure, high temperature, and strong corrosion conditions.


It is used under the conditions of 200℃ and vacuum below 0.096MPa, and the operation of rapid cooling and rapid heating or alternating cooling and heating will not cause The polytetrafluoroethylene layer falls off, bulges and collapses, and expands and deforms, so as to integrate steel fluorine.

Performance: Medium working temperature: -50℃~180℃

Medium working pressure: positive pressure: 2.5MPa, negative pressure resistance 70KPa at room temperature

Corrosion resistance: steel PTFE composite pipe, in addition to molten metal lithium, potassium, sodium, chlorine trifluoride, three under high temperature

Except for oxygen fluoride and high-flow liquid fluorine, it can resist almost all chemical media.

Atmospheric aging resistance: radiation resistance and low permeability: long-term exposure to the atmosphere, the surface and performance remain unchanged.

Incombustibility: The oxygen limit index is below 90.

Acid and alkali resistance: insoluble in strong acids, strong alkalis and organic solvents.

Oxidation resistance: resistant to corrosion by strong oxidants.
