The centralized structure of the company SMIT Group allows us to perform the most complex work, large orders and shorten the delivery time of finished products.

Quality parameters exceed national standards.

Due to well-run logistics system we manufacture and deliver our products right on time. SMIT Group produces wide range of pipes, bends, branches and other components for preinsulated pipelines.. To guarantee reliability of the pipeline we constantly monitor all processes for quality. Our customers always get products that meet and exceed national
standards.

Our production sites occupy an area of more than

52 thousand sq. meters.


Our production

capacity is

1000 kilometers

of preinsulated pipes,


600 kilometers

of flexible preinsulated pipes


and

100 000 fittings

(pipe elbows, connectors etc.) a year.

State-of-the-art equipment.

We use world-class equipment, which is made in accordance with SMIT Group requirements. SMIT Group suppliers are: Krauss Maffei, Spiro, KWH Pipe,
Cincinnati, Canon, Widos, Bomar Transvers, EWM, Esab,
Lincoln Electric, OTECO, Lindab, ROCCIA etc.

We use our own railway branch to speed up shipment and delivery processes.

We use:

Purpose-built equipmentallows us to successfullyimplement modern technologies and compete with the leadingglobal manufacturersof preinsulated pipes.

Process of production includes following stages:

  • Incoming inspection of raw materials;
  • Shot blasting steel pipes;
  • Setting spacers on the steel pipe;
  • Remote control system cable drawing;
  • Placing the steel pipe into the pipe case (zinc or polyethylene);
  • Heating the construction in thermal stabilization camera;
  • Foaming the pipe with polyurethane;
  • Testing the operative remote control system;
  • Final check by quality control department.

When making bends, branches and other fittings additional operations are included:

  • Cutting pipes into sections;
  • Gas welding;
  • Ultrasonic control of welding joints;
  • Buttwelding of polyethylene.

We use advanced welding technology for galvanized steelsbased on the results of research of leadingspecialists working in welding production of SMIT Group.
We have achieved maximum corrosionresistance of fittings’ galvanizedsteel elements.

Reliability of the pipeline is ensured by the following conditions:

  1. Polyurethane foaming on cyclopentane basis;
  2. Implementing of 5 welding methods;
  3. высококачественная сварка металла,
  4. High-qualitymetalwelding;
  5. Ultrasonic control of welding joints;
  6. High quality butt-welding of polyethylene pipes up to ∅ 1 600 mm;
  7. Heat shrink sleeves stand 2000 test cycles over the European norm of 120.

5 welding methods are implemented in SMIT Group.

  1. 1.Manual metal arc welding;
  2. 2.Mechanized arc welding;
  3. 3.Automatic submerger arc welding;
  4. 4.Combined (mechanized& automatic) welding;
  5. 5.Flash-butt welding.

SMIT Group is Russia’s only company that mastered efficient cyclopentane foaming for pipe insulation. This technology is widely used among preinsulated pipelines manufacturers all around the world.

Cyclopentane provides stableinsulation properties of polyurethane foam for 30 years at constantheating media temperature of 160° C andincreases thermal insulation efficiency of thepipe up to 0,027 W/(m*K).

Use of cyclopentanein production keeps heat-conduction coefficient stable throughout the service life of pipeline.

This reduces costs and ensures ultimate service life of heating systems.

Polyurethane foaming based on cyclipentane meets internationalenvironmental safety requirements.
