After looking at the above diagram API fastener production process, do you think that the production of API screws is not so simple?!It's not easy, every process has to be controlled.In particular, raw materials and heat treatment pass, the two gateways for an important process.Unqualified raw materials, the follow-up process is not qualified products.The rest of the heat treatment process is the core process, only high has 2 advanced heat treatment production lines, in 24 hours non-stop for high-quality fasteners escort!

Key words: API screw, API bolt, API stud, API nut, API stud bolt, API full thread stud, API double-headed stud, API hexagon bolt, API bolt and nut, API stud and nut.

HIGH-QUALITY CUSTOMER GROUPS：

At the early stage, with the help of Suzhou Valve Factory of China Nuclear Industry Group, in 1995, the company started to provide high pressure fasteners that were fully compliant with ASTM standard series for Suzhou Kaifu Valve Factory, a joint venture of the United States company CIRCOR and Suzhou Valve factory. Since then, the company has embarked on a path of cooperation with internationally renowned companies. The well-known manufacturers we are serving are: Neways Valves, KITZ, LARSON & TOUBRO LIMITED (Chinese factory), THEWM POWEU COMPANY (Chinese factory), NEWCO-NEWMANS DIV (Chinese factory), China Huanqiu Engineering Co., Ltd., Yitai Coal Industry, Sinopec, China Founder, and other well-known domestic and international high-quality companies.

To produce high-quality fasteners is our commitment to customer. Pure-minded, we are concentrated on our specialized field. Over the past decades, we have been consistently sticking to the operation idea of conscientious operation, whole-hearted service, and the pursuit of perfection, striving to build a high quality image of fasteners bearing the “Y” sign in the industry.
