Yanshan Yahui Pipe Industry Co., Ltd. is a new force established on the basis of a time-honored pipe industry group founded in the 1980s. Relying on the group's accumulated core technologies and production experience, together with strict quality control and physical and chemical testing, we manufacture professional pipe fittings in strict accordance with all applicable standards. Our products are widely used in petroleum, petrochemical, chemical, thermal power, boiler, main steam piping, fertilizer, aviation and nuclear power, metallurgy, shipbuilding, machinery and military industries.
The company attaches great importance to its talent strategy and actively attracts young people with new technologies and new ideas. Backed by the strength of the time-honored group, the company funds further training for its managers every year to improve management, optimize management concepts and train mid- and high-level technical workers, so as to secure the production process and improve product quality, and firmly adheres to the production philosophy of "never making the most expensive product, only making the best product".

Testing equipment includes a full-element direct reading spectrometer, portable direct reading spectrometer, qualitative spectrometer, magnetic particle, ultrasonic and metallographic testing equipment, a multi-functional tensile testing machine, a pendulum impact testing machine and a -65 Deg C low-temperature chamber. Our products mainly include elbows, pipe bends, tees, reducers, pipe caps, sharp elbows, flanges, socket weld fittings, forged fittings and special fittings.
All products are manufactured to national standards GB, DL695, GD87, GD2000, SH, HG as well as American standard ASME (ANSI), German standard DIN and Japanese standard JIS. We solemnly promise that every fitting we produce is inspected piece by piece for geometric dimensions and appearance, ultrasonic thickness measurement, ultrasonic nondestructive testing, magnetic particle and dye penetrant testing. At the same time we are firmly market-oriented: for customer-specific customized and difficult fittings we apply the same relentless pursuit of perfection. Over the years we have been highly praised by customers at home and abroad and have established a solid reputation in the industry. Today our products sell steadily not only in China but also in North America, Central America, Europe, Japan, Singapore, Russia and other concentrated customer regions.
