Product Detail

Large Diameter LONG WELDED ERW LINE PIPES

HIGH FREQUENCY WELDED HFW / ERW STEEL Line pipes are used to transport oil and gas, water, mineral slurry and other fluids. Our line pipes are manufactured in accordance with API Spec 5L.

Pipes are manufactured according to the requirements of the following standards:

• Council Directive 89/106/EEC,

• Council Directive 97/23/WE,

• PN-EN ISO 3183,

• PN-EN 10219-1/2,

• API Spec 5L,

• ASTM A53,

• PN-EN 10217-1,

• PN-EN 10217-2,

• PN-EN 10217-3,

• PN-EN 10224.




Pipes are manufactured in diameter range from 114,3 mm to 457.2mm, in production lengths from 6 m to 20 m. Pipes are supplied with plain or bevelled ends, after hydrostatic test and automatic non-destructive ultrasonic or eddy current tests.

During production process the heat treatment is performed to eliminate stresses generated in the seam as well as to guarantee both homogeneous steel structure and higher strength properties.

Upon the customer's needs pipes are supplied as: bare - without protection coating, or with external three-layer polyethylene (PE) or polypropylene (PP) anticorrosion coatings and with internal either cement or epoxy lining. Against agreement pipes may be supplied with other anticorrosion protection e.g. galvanized pipes.
