Line pipes

Fiberglass line pipes of The Scientific Industrial Enterprise «Fiberglass Pipe Plant», Ltd production successfully used in transportation of corrosion aggressive liquids. Application of Fiberglass Pipelines allows both to solve the problem of corrosion of pipes, deposits of salts and paraffin, to reduce the hydraulic losses in the pipelines, to reduce the cost of construction and erection works, costs of care and protection of pipelines. Fiberglass pipes do not have alternative in transportation of high-sulfur and paraffin oils, liquids active to corrosion, also used for technological pipelines and in preparations of oil and tech liquids. Application of Fiberglass Pipes significantly reduces operating and construction costs of pipelines and ensure safe working pipeline for more than 25 years. Fiberglass pipes of our manufacture used in companies such as ОАО «TATNEFT», ZAO «PECHORANEFTEGAZ», ОАО «RN –SEVERNAYA NEFT»,ОАО «RN-UDMURTNEFT», ОАО «ULYANOVSKNEFT», ОАО «TATNEFTEPROM», etc.

APPLICATION OF LINE PIPES

Oil piping systems;

- High waterways of maintaining reservoir pressure;
- Fault piping;
- Technological pipelines;
- Pipelines transporting chemically aggressive fluids;
- Fire waterways.

In addition, possible to use pipes in public services, housing and civil construction as:

- Piping systems, drinking and industrial water supply;
- Sewerage pipelines;
- District heating networks.

ANVANTAGES OF USING FIBERGLASS PIPELINES:

- Period of operation for transportation of corrosive liquids more than 25 years;
- Piping systems are not subject to corrosion(pipe material inert to acids, salts, alkalis, hydrogen sulfide and oxygen-containing compounds);
- A small mass of pipes, which provides a high strength (average weight of fiberglass products up to 5 times less than the mass of the same metal);
- Piping systems are not subject to deposits of paraffins, salts and solid precipitation;
- Provides a low hydraulic resistance, due to smooth inner surface;
-Low cost of maintenance;

APPLICATION OF FIBERGLASS PIPELINES WILL:

- Increase the period of accident-free operation of pipelines for oil and gas;
- Reduce the pressure on the height of the column or the length of the pipeline (It makes possible the use of fiberglass pipe of smaller diameter than the metal);
- Eliminate or reduce the deposition of salts and paraffins;
- Reduce accident risk of using pipelines;
- Eliminate the need for corrosion inhibitors;
- Reduce the number rises of columns;
- Investigate the status of operating columns of wells without a lift pipe tubing;
- Reduce the cost of maintenance and operation column tubing and pipes;
- Reduce the cost of installation and construction of pipelines due to no need for welding, pipe laying, etc.

где: Lt – длина трубы, D – наружный диаметр трубы, Dm – диаметр раструба, d – условный внутренний диаметр, t – толщина стенки трубы, L1, L2 – длина зон труб, на которых разрешена работа ключами

Lt - length of tube, D - outer diameter of the pipe, Dm - bell diameter, d - internal diameter of a conditional, t - thickness of pipe wall, L1, L2 - length of pipe zones, which enable the keys. Pipes and shaped products are manufactured with threaded connections. Integral fittings «nipple - clutch» threaded EUE 8rd API Long meets the requirements of API 5B, consistent with the thread size and thread profile of a triangular metal pump and compressor casing with a step of 8 threads per inch (GOST 632-80 and GOST 633-80) . The main difference is that the total length of the threads Fiberglass pipe is longer than a similar metal (photo thread). For the assembly line pipe is produced with all the necessary range of shapes of products:

- branches, 90º; 45º; 22,5º; 11,25º
- Tees;
- Flanges;
- Sleeve;
- Transitions

Work on installation of the pipelines are made by hand without the use of heavy equipment (welding machines, pipe layers, etc.)by brigade of installers (2 to 4 people). The pipes are mounted by means of chain and torque wrench (to control the time of screwing), using lubricant TF-15 (for mounting at sub-zero temperatures is supplied special winter lubricant TFW-15).

Specialists of The Scientific Industrial Enterprise «Fiberglass Pipe Plant» implement integrated order tracking: A survey of the site, assist in the integration, training, conduct supervision and construction works, providing technical assistance, after tracking.
