Pipes

Hollow Sections

Square and rectangular section shaped pipes are produced by sectioning circular pipes on the electric-welding mill line. Application: building structures for different applications.

Weld shaped pipes are produced from St 1, St 2 St 3 carbon steel grades. 08.10 and 20 sleel grades, as well as from S235JRH. S355J0H S355J2H. E155. E190. E195, E220, E235. E260 grades.

Pipes are manufactured at the electric-weld pipe units by high-frequency induction welding.

General Purpose pipes

Water and gas pipes with small diameters from12.7 to 108mm (0,5-10,6″) are produced from carbon steel grades S185. S195T, S235JRH. P195TR1, P23STR1 (and other).

Pipes are produced by high-frequency welding with induction current lead.

Pipes are subjected to hydraulic and mechanical tests. Welds undergo non destructive testing.

Square and rectangular section pipes are shaped from round electric-welded pipes on the line of the electric welding mill.

At the consumer’s request pipes are packed in hexagonal and box bundles. Pipe bundles are provided with removable shipping straps for fixing in trans-shipment points and storage without additional pulling appliances.

    Oil and Gas Line Pipes

    ERW pipes are made by Vyksa Steel Works. Pipes fully comply with requirements of International standards.

    Oil and gas tine pipes are made with diameters from 114 to 530mm [4 1/2 – 20″) and wall thicknesses from 4.0 to 12.7mm (016-05″). Pipes are produced by high-frequency welding from carbon and low-alloy grades: up to X70.

    During production pipes undergo multi-stage non-destructive testing, acceptance mechanical tests of base metal and weld and 100% hydraulic pressure test.

    All pipes are supplied pte-treated; with local heat treatment of weld or bulk heat treatment.
    Pipes undergo multi-stage non-destructive testing using an eddy current flaw detector, automatic and manual ultrasonic flaw detector, mechanical and 100% hydraulic tests.

    Large Diameter Pipes

    Production of large diameter SAWL pipes

      longitudinal etectiic-weldod large diameter pipes are manufactured by submerged arc welding {SAW).
      At present targe diameter pipes can be manufactured by two Independent lines having different pipe foitmng processes- UOE and JC0.

    API Spec St. ISO 3183

    large-diameter-pipes

    • UOE and JCO process: pipes ore manufactured from B X42. X-46, X52. X56. X60. X65, X70. X8O (API Spec 51) and L245, L290, L360, L415, L450, L485, L555 (ISO 3183) grades
    • JCO process: pipes are manufactured from 8, X42, X46, X52, X56, X60, X65, X70, X80 (API Spec 5L) and L245, L290, L360 L415, L450, L485, L555 (ISO 3183) grades

    Basic Equipment

    Pipes are produced on two separate lines using different production methods – UOE Line and JCO Line. Pipes can be made with either one or two longitudinal welds.

    UOE Line

    Produces pipes with diameter of 508 -1067 mm (20-42″) and wall thickness from 8 to 32 mm (0.28-1.26*): strength grade X80. Design capacity is 1012 thousand tons of pipes per year.

    JCO Una

    Produces pipes with diameter of 508-1422 mm (20-56″) and wall thickness from 8 to 48 mm (0.28-L89″). strength grade up to XlOO. and working pressure up to 24.7 MPa (250 atm.). Design capacity is 950 thousand tons of pipes per year.
