Pipe lining

Lining is used to protect heat transfer equipment, chemical equipment, pipelines, pickling baths, containers, tanks, vertical vessels, reactors and other equipment from thermal and chemical effects of corrosive mediums. Lining helps to extend the life of equipment and save money on replacement caused by wear. Fluoropolymers are widely used for lining. PTFE lining is popular in different industries as it has a high chemical resistance and the ability to operate at high temperatures.

Pipe lining is usually used to protect pipelines from the effects of corrosive mediums being transported. However, it is necessary to line even those pipes that transport water, as it causes the depassivation of metal surfaces.

We at Plastpolymer-Prom offer services in PTFE pipe lining to the specifications of the customer. PTFE pipe lining gives pipes the following features:

  • a large range of mechanical properties;

  • good dielectric properties;

  • a high dielectric strength;

  • a low coefficient of friction;

  • low wear rates;

  • resistance to a variety of corrosive mediums at room temperature and elevated temperatures;

  • durability and resistance to corrosion and radiation;

  • a low gas permeability;

  • zero flammability or self-extinguishing properties.

We produce lining for a number of products, such as:

  • steel pipes – when lined with PTFE, they can be used to transport any corrosive mediums (except for molten alkali metals, fluorine and chlorine trifluoride) at a pressure of up to 1.6 MPa;

  • tees, elbows, crosses, reducers, and steel flanges – when lined, they can be used to connect lined pipes to main pipelines transporting corrosive mediums;

  • steel bellows – when lined, they can be used to connect pipes transporting corrosive mediums and to compensate for changes in the linear dimensions of pipelines at various temperatures (from -60 °C to + 250 °C), and to reduce vibration load.

Pipes, tees, elbows and other products that the customer wants to line should be produced by the customer according to drawings that have been approved by our engineers.

Lined pipes and pipelines have operating temperatures ranging from -60 °C to + 230 °C.
