SAW-Spiral/Helical Welded Pipes for Piling Works & Pipelines

Odelya® Spiral Submerged Arc Welded (SSAW) Carbon Steel Pipes are manufactured from hot rolled coils straightened in a strip, which are then formed in required angle to produce a cylindrical spiral shape of desired diameter. In submerged arc welding process an electric arc is produced in gas environment by applying electric current. The edges of a strip are carefully welded internally and externally by submerged arc welding process using single, tandem or triple techniques with continuously supervision to prevent possible defects. Quality and maximum performance of entire weld are assured by computerized inspection process, applied during and after HSAW welding.

Odelya® SAW Steel Pipes are widely used in various applications, such as pipeline construction for conveyance of natural gas, oil, water and other flammable & nonflammable liquids conveyance and distribution, water supply systems (high temperature water as well), sewage, liquid hydrocarbons conveyance and storage, irrigation, refineries, petrochemical and hydropower plants, crude oil loading terminals, piling purposes, piles industrial pipelines, foundation piles, pressure air pipelines, natural gas (LPG) installations, industrial pipe network, combi-wall construction, and in chemical industry.

Submerged arc welded steel pipes can support great weights and therefore are used in construction of ports, harbors and jetties, pierces, onshore and offshore platforms, bridges, steel structures, advertising billboards and main roof supporters of exhibition halls, stadiums.

Pipe End and Pipe Joints Details

Considering the utilization purpose and dimensions of steel line pipe, the following pipe ends or joint details can be selected (AWWA C 208, BS 534): plain, square cut / bevelled, welded joint, flanged joint, cylindrical socket and spigot joints, spherical (belled) spigot and socked joint plain end for special coupling, butt welded and threaded-end pipe.

Surface Conditions

Odelya® SAW pipes are delivered as bare (black), coated or lined (3LPE, 3LPP, PU, Epoxy, FBE, etc.).

For coating types and coating tests please refer to

Odelya® Project-oriented line pipes and piling pipes are manufactured under precise quality control, which starts from procurement of raw materials continues during manufacturing and welding process to prevent any flaw. Therefore, third part inspection is an essential part of our business flow. Quality assurance policies of Odelya® ensure high quality of used material, weld, coating and lining, superior mechanical and technological properties. Quality tests are applied to meet strict production standards’ specifications and customer requirements for any special project.

Material Chemical Analysis
Spectral analysis of the chemical composition

Non-Destructive Tests

Ultrasonic test: Automatic and manual ultrasonic testing precisely detects flows and monitors weld quality using high frequency sound waves. (Ultrasonic weld seam test, Ultrasonic lamination test). Radiological Inspection (Radiographic and Radioscopic tests): Evaluating quality and integrity of weld area of the entire pipe.

Visual & Dimensional Inspection
Accurate information about dimensions and quality of tubes is provided using tape, caliper, ultrasonic device, gauge and cord.

Hydrostatic Test
Leak Tightness test evaluates the density and firmness of entire pipe. Testing of leakage in the welded areas by high pressure water applies according to further application and requirements. Mechanical & Technological Properties

Tensile test: Determining mechanical properties, such as yield strength, tensile strength, Young’s module, deformation, elongation, strain hardening behavior, and reduction of sample.

Bending test: Evaluating ductility of the tubes and the welds to resist cracking or other surface irregularities during one continuous bend of the material. (Guided Bend Test)

Impact test: Determining a total energy required to break the test sample by fracturing impact at high velocity (Charpy V Notch Impact Test, Drop Weight test DWTT).

Macrographic and Metallographic Examination
Revealing the structure of metals and their alloys with light optical or scanning electron microscope.
