Odelya International Steel

ERW Water & Gas Pipes

Odelya® ERW Water and Gas carbon steel pipes are used in civil and industrial installations for water and gas distribution applications. 

Odelya® High Frequency Electric Welded Pipes are manufactured by cold-forming a steel sheet into a cylin- drical shape. The manufacturing process of Odelya® ERW tubes uses high frequency alternating current, which assures a higher quality weld. 

Due to high durability against  seam corrosion, hook cracks and strong seam bonding, demand for ERW (Electric Resistance Welded) steel tubing in fluid and gas conveyance applications has been increased by years. Odelya® offers  wide range of environment-friendly products with superior proper-ties for safe and healthy consumer usage to meet the global demand. 

Odelya® ERW Water & Gas Conveyance Tubes vary on their material types, surface conditions, processing types and are available as: carbon or stain- less, black (self-colour), surface-coated, galvanized, threaded and coupled, plain or bevelled end…

QUALITY TESTS

Hydrostatic Test
Testing of leakage in the welded areas by high pressure water applies according to further application and requirements (Leak Tightness).
Non-Destructive Tests
Eddy Current Test: Detection of the defects on the surface and testing quality of the weld and the material using electromagnetic device.
Ultrasonic Test: Automatic ultrasonic rotary plant precisely detects possible defects in the weld zone.

Visual & Dimensional Inspections
Accurate information about dimensions and quality of tubes is provided using tape, caliper, ultrasonic device, gauge and cord.
Chemical Analysis
Spectral analysis of the chemical composition
Mechanical & Technologıcal Properties
Tensile test, flattening test, bending test, impact test, drift expansion test, fracture toughness test
Metallographic Examination
Revealing the structure of metals and their alloys with light optical or scanning electron microscope
Surface Coating Tests (for coated pipes)
Coated ERW Steel Pipes are also tested to assure optimum impact resistance, peeling power, coating elongation, indentation hardness, adherence quality, bond strength, coating resistivity, film thickness etc., which are applicable according to the requirements of related standards and upon request.
