Technical Support
Supplying ERW steel pipe & Tube

ERW steel pipes means Electric Resistance Welded Pipes. 
Sunny Steel Enterprise Ltd. can provide the full range of ERW steel pipe to meet your requirements.

ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. 
ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes. 

All of the products we are supplying can reach the international standard like: ASTM, JIS, DIN, EN, API, BS , 
Our company's production is carried out in accordance with TS EN ISO 9001:2000, API5 L, ISO 14001:2004 
and ISO9001,SGS Integrated Management(quality) Systems. 
Production in our facilities is also realized in accordance with the international standards such as TS, DIN, AWWA, ASTM, BS, UNI, JIS, GOST, ANSI, ISO. 

Our product finds its usage for Agricultural purposes, Drinking Water for housings, in collieries for extraction of Water,
Thermal Powers, Transports- for all kind of pipeline usage . 

Hand pumps for deep boring wells, as a strong protection for cables by Telecom Department, Structural Purposes etc. 

ASTM A 53 straight seam steel pipe can be used in transferring water, air and heating steam, etc., 

in accordance to the GB/T 3091-2008 standard, which is applicable to welded steel pipes for low pressure liquid delivery 

The raw materials of the same width of the API 5L black steel pipe can be processed in different molding angles to manufacture steel pipe in various diameters which are in accordance with the standards. The API 5L black steel pipe is extensively used in transferring corrosive matters such as petroleum and natural gas. 

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. The pipe internal stress is very small and uniformly distributed after the full- length expansion. 
The corrosion and cracking of the pipe owing to stress can be effectively prevented. 
The application of welding on site is very easy because of the high dimension precision;
The inside and outside welding are performed after the tack welding , so the welding process is very stable with good weld quality; 

The NDT is easy to perform on the weld during production and field operation as well;
The length of the weld is shorter than that of the non-longitudinal seam pipe, so the probability of defects occurrence is very low; The coverage of the pipe specification is very wide. The pipe can be either in large diameter with thick wall or in small diameter with thick wall. 

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.

The technical delivery conditions for the non-alloy and alloy electrically welded steel pipe with circular cross section, which has a rise in temperature in both the TR1 and TR2 experiments, are defined.
