Weld steel pipes

Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding.

Sunny Steel produce an extensive selection of welded steel pipe including ERW, HFI, EFW, LSAW, DSAW and UOE type carbon steel pipe along with their respective flanges and fittings.

J-ing, C-ing and O-ing pipes
The mill adopts continuous axis contorting J-C-O(J-ing, C-ing and O-ing)process with characteristics of high forming accuracy and efficiency as well as balanced distribution of forming stress.
Special Welded Tubes
Special Welded Tubes
Stainless steel oval tube offered in grades 304 and 316 in a wide choice of sizes.

Steel surface treatment is mainly anti rust, the following is anti rust process:
First step is to clean, use cleaning solvent emulsion cleaning the steel surface, in order to achieve the removal of oil, grease, dust, lubricants and similar organic matter, but it can not remove the steel surface rust, oxide, solder medicine.
