Product  Type: Seamless boiler pipe, Boiler Seamless Tube, Seamless Boiler Tube, Boiler Pipe. Fire-tube boiler is a type of boiler in which hot gas passes from the fire through one or more pipes that pass through a sealed water container. The heat of the gas is transferred through the wall of the tube through heat conduction, heating the water and eventually generating steam. Fire tube boilers are the third of the four historical types of boilers: low-pressure tank or “haystack” boilers, flue boilers with one or two large flues, fire tube boilers and high-pressure boilers with many small tubes. Application: Used for superheated pipelines, steam pipeline, boiling water tube.

Line pipe is a tube made of high strength carbon steel. It is typically manufactured according to the API 5L metallurgical specification developed by the American Petroleum Institute (API). The raw material can be either seamless or welded carbon steel or stainless steel piping. This product can be used to build pipelines that transport a variety of resources including natural gas, oil, petroleum, and water. API 5L line pipe is available in various diameters ranging from two inches to 48 inches. Its size and diameter required for a pipeline vary according to the amount of gas or liquid that it intended to carry and the pressures it must withstand.

Application: Oil and gas pipeline, water transmission, liquid transportation, Building construction, Steel structure construction,  Offshore/Onshore construction, Piling works, Electricity, Heating power and etc.

The UOE mill features the most advanced technology and process, achieves high production efficiency, stable product quality and is equipped with complete inspection equipments. UOE mill adopts U & O forming, the formed pipes are welded inside through five internal welding stations with three wires, and welded outside through four external welding stations with three wires. In accordance with different requirements of the customers, the welded pipe can be expanded either by mechanical or hydrostatic expander to improve dimensional accuracy, and eliminate residual stress.

Test: Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation), Technical Properties (Flattening Test, Bending Test,  Hardness Test, Impact Test), Exterior Size Inspection, Hydrostatic Test, NDT TEST ( ET TEST, RT TEST, UT TEST).
