ERW Steel Pipe

HFW Steel Pipe

Specifications Range
Out Diameter up to 26inch
Wall Thickness up to 1inch
Length 3.0m-18m

Application Areas

HFW welded steel pipes are widely preferred in Oil, Natural Gas, Water and other liquids transportation and distribution lines, heating, cooling, ventilation piping and steel structures for construction and other general purposes by means of precise production tolerances and high capacity manufacturing method.

Pipe Length
Husteel is able to manufacture and supply high frequency welded pipes up to 16 m. in unit length.

Pipe Coating
Coating mills apply pipe coatings to protect the line pipe from corrosion. Often, the coating mill is located adjacent to the pipe mill, so line pipe moves directly from the pipe manufacturer to the coating facility.


Resource:
High frequency welding
testing facilities for fracture mechanics studies
corrosion & metallurgical test equipment
non-destructive testing
process advice & troubleshooting
tailored training courses


Salient Features
Capability to manufacture pipes as per API 5L Grade API X-80 or equivalent
All testing facilities in-house to meet International Standards


Based on the customers requirements we can manufacture erw pipes and tubes of different size and shape. We have a very large production capacity of erw pipes and tubes. ERW pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW pipe is available in lengths from single random to 120 feet depending on mill capability. ERW pipe is available with square ends or beveled for welding, threaded and coupled and victaulic grooved. Surface finish are available in black or bare, or with protective coatings. 

For pipes or tubes size 4 inch (10.2mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes. The electrodes are copper disks connected to the secondary of a revolving transformer assembly.
