About us

Established on September 4, 2019, Hunan Youqin Iron and Steel Trading Co., Ltd. is supported by Youfa Group Hunan Office and Youfa Steel Pipe Sales Company. We are a dynamic and innovative team focused on serving end-use customers. Adhering to Youfa’s core values of win-win cooperation, integrity, and morality, we mainly promote a full range of Youfa brand products, including: hot-dip galvanized steel pipes, galvanized seamless steel pipes, plastic-lined composite steel pipes, plastic-coated composite steel pipes, high-frequency welded pipes, spiral submerged-arc welded pipes, stainless steel pipes, as well as grooved fittings, malleable iron fittings, plastic-lined pipe fittings and stainless steel pipe fittings. We also provide sales and consulting services for angle steel, sleeves, channel steel and other supporting products. The company’s operation is supervised by Youfa Group and its Hunan provincial sales company. With professional supply chain management, we integrate spot resources from Youfa’s major production bases in Tianjin, Handan, Tangshan, Hancheng, Liyang and branches in Hunan. We have supplied key materials for many provincial key projects, including Changsha IFS, Hunan Provincial Department Building, Changsha Xinhualian Tongguanyao Tourist Resort, Yuetang International Trade City, Jinqiao International Trade City, Changsha IKEA, Gan-Xiang Industrial Park, as well as numerous commercial complexes and residential projects across Hunan Province.

Quality Control

We implement a full-cycle quality management system covering raw material incoming inspection, production process monitoring, finished product performance testing and factory inspection. Equipped with a full set of advanced testing equipment, we strictly control chemical composition, mechanical properties, corrosion resistance, pressure resistance and safety performance of each product, to ensure stable and reliable quality that fully meets international standards and customer requirements.

Universal Testing Machine(UTM)

The electronic universal testing machine is a new generation of dual-space microcomputer-controlled instrument. It features an elegant appearance, easy operation, stable and reliable performance, no pollution, low noise and high efficiency, and can meet relevant national and international standards.

Salt Fog Test

The salt spray test simulates the damage caused to products by the coastal marine climate, and inspects the corrosion resistance of products.

Drop Weight Tester

The drop weight impact tester has functions such as automatic hammer suction, automatic zeroing, automatic lifting, and prevention of secondary impact. This equipment adopts a double-tube structure, digitally displays the impact height, and is safe and reliable in operation.

ARL 3460 OES

Based on the atomic emission principle, the ARL 3460 direct-reading spectrometer is mostly used in industrial analysis. It features fast analysis speed and reliable analysis results, and is an instrument for quantitatively analyzing the content of chemical elements.

Flue Gas Analyzer

The smoke and flue gas tester adopts the Pitot tube parallel isokinetic sampling method to collect particulate matter in the exhaust gas of fixed pollution sources, determines the mass via the filter gravimetric method, and performs qualitative and quantitative analysis of flue gas components using the potentiometric electrolysis method.By measuring the concentration values of smoke and flue gas, we can conduct self-supervision to ensure that the waste gas emission of the plant meets the national emission limit requirements.

Atomic Absorption Spectrometer (AAS)

Also known as atomic absorption spectrophotometer, the atomic absorption spectrometer analyzes metal elements based on the absorption of characteristic radiation by ground-state atomic vapor. It can sensitively and reliably determine trace or ultra-trace elements.

Impact Testing Machine

The impact testing machine is used to determine the impact resistance of metal materials under dynamic loads, so as to judge the properties of materials under dynamic loads. This machine has a large impact energy and is suitable for ferrous metals with high impact toughness. The testing machine is semi-automatically controlled, with lifting, pendulum setting, impact, and pendulum release all electrically controlled. It can automatically swing the pendulum using the remaining energy after the impact test to prepare for the next test.

Thermo Fisher iCAP RQ ICP-MS

The Thermo Fisher iCAP RQ ICP-MS inductively coupled plasma mass spectrometer is the smallest benchtop model in the world, featuring a compact design and easy maintenance. The real-time working status of the plasma can be observed on the controller's computer display via the Plasma TV function. With a patented chip design, it meets two different application requirements: high salt tolerance and high sensitivity analysis. It is suitable for elemental analysis, isotope analysis, and elemental speciation analysis of various samples in a wide range of application fields, including environmental protection, food, geology, metals, biological samples, and chemical material analysis.

Thermo Fisher Trace 1300GC-ISQ 7000MS

The Thermo Fisher Trace 1300GC-ISQ 7000MS gas chromatography-mass spectrometer adopts a wireless assembled ion source with an integrated design. The pusher, ion box, source lens, and RF lens are integrated in a single sleeve, facilitating quick disassembly and cleaning of the ion source in daily maintenance. The S-type ion channel must adopt a high-axis optical design to improve the low-concentration detection limit. The S-type ion channel can simultaneously protect the four poles from contamination. It is used for qualitative and quantitative analysis of trace or ultra-trace volatile and semi-volatile organic compounds in gas, liquid, and solid samples, and can be used for the confirmation of organic substances.
