Home > Company Introduction
Hunan Yige Special Steel Technology Co.,Ltd was founded in August 2015.It’s a high-teach enterprise specialized in the production, R&D and sales of the high-performance and high-precision of special-shaped steel pipes, seamless pipes and other cold drawn materials.we are passed ISO9001, 14001, 18001 ,450001,CE and other system certification. The company has several sets of chain drawbench machine and hydraulic drawbench machine, one roller bottom type natural gas heat treatment furnace, several sets of head making, straightening, sawing, surface treatment and machining equipment, and equipped with a full set of physical and chemical testing equipment.
Annual output more than 20,000 tons of seamless square pipe, special-shaped steel pipe, round pipe and other products with various materials, perimeter of 40-1800mm and wall thickness of 1-30mm. Our products are characterized by “high, precision, special and different” (high strength, high precision, special materials and special-shaped section). Various special-shaped steel pipes can be developed, designed and produced according to the different requirements of customized to meet the high-quality and high-performance, high strength, high toughness, easy welding, impact resistance, fatigue resistance, wear resistance and corrosion resistance. Our company developed The low carbon, low alloy and ultra-high strength seamless rectangular pipe has a yield strength of up to 1000 MPa, excellent comprehensive properties such as toughness, low temperature impact and fatigue life, and good application effect.
Now our factory products have been widely served high-end equipment manufacturing industries at home and abroad, such as aviation, military industry, nuclear power, marine industry, shipbuilding, high-speed rail, engineering machinery, construction machinery, steel structure, petrochemical industry, agricultural machinery, textile machinery, passenger cars, special vehicles, vehicle axle, water conservancy and hydropower, communication towers, pressure vessels and other industries. We have cooperated with many well-known enterprises in many industries, such as China Hi-tech, China Railway Construction Heavy Industry, Zoomlion, Sany Heavy Industry, Sunward Intelligence, Yutong Heavy Industry, Dongfeng Motor, Chery Automobile, China Yto, Modern Agricultural Equipment, and have won the trust and praise of customers.

Three keys to quality control of YIGE:
Good billet is the basis of good pipe. We strictly control the incoming inspection, all our products are from the brand steel mill (The series of low alloy and high strength customized products mainly use Valin Hengsteel billets) and strict physical, chemical, appearance size inspection of incoming materials, to prevent unqualified products flowing into the production link.
Develop scientific and complete work instructions, process inspection specifications and related standards; The combination of self-inspection, mutual inspection and special inspection; The inspection of Process quality is strict to prevent unqualified products flowing into the next process; Quality records are timely, true, complete, clear and traceable.
we have professional testing equipment and testing personnel, the laboratory is equipped with 18 elements of Japan Shimadzu direct reading spectrometer, 60 tons of universal material testing machine, -60 degree impact meter, hardness tester and other equipment. The appearance and size of the steel pipe are tested one by one, and the mechanical test of the finished steel pipe is carried out according to the batch, and the record is stored in the file and sealed sample.
