Odelya International Steel

Electric Resistance Welded (ERW) Boiler & Pressure Tubes

Odelya® ERW Boilers and Pressure Tubes are made of heat resisting carbon and low alloyed steels, therefore, can withstand the load at high pressure and high temperature. Odelya® carbon steel Pressure and Boiler Pipes are supplied as cold drawn or hot rolled with required surface protection, ensuring the long lifespan of steel pipes at the most hostile conditions. High quality and wide range of Odelya® Boilers and Pressure Tubes meets requirements of a rising demand in many industries and projects. 

Odelya® ERW Boiler & Pressure Tubes vary on their material types, surface conditions, processing types, and are available as: carbon or stainless, black (self-colour), surface-coated, galva- nized, plain or  bevelled end…


Odelya® Welded Pressure and Boiler steel tubes are used for heat exchangers, steam and marine boilers in boiler industry, steam superheaters, central (district) heating and cooling sistems, distribution of gas, high and low pressure liquid transmission, economisers, pressure equipment, refrigeration, water mains, sewage pipes, etc.

Surface Conditions

Black self colored/uncoated, surface protective coated (black varnished), hot-dip galvanized (zinc-coated).

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 (type TC2 mandatory)
Eddy Current Test: Detection of the defects on the surface and testing quality of the weld and the material using electromagnetic device (on-line). Testing by overpressure can be applied on request.

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 & Technological Properties
Tensile test, flttening test, flange test, drift expansion, bending test / weld bend test, iImpact test, fracture toughness test
Metallographic Examination
Revealing the structure of metals and their alloys with light optical or scanning electron microscope.

Note: Applied tests vary according to the related standard and application. Please refer to page 52 for more details about our Quality Assurance Policies.
