Zhejiang Pump Valve Quality Inspection Center cooperates with international certification agencies

Recently, Zhejiang Pump Valve Quality Inspection Center successfully cooperated with two international authoritative certification companies, TUV and DNV, and completed the fire test and certification of the first batch of 29 valve products.

The industry believes that this cooperation has solved the two major problems in the Wenzhou local fire resistance test and export of valve products require foreign fire authority certification authority certification. At present, there are 1,000 valve manufacturing enterprises in Wenzhou City, and the products are exported to Europe, America, Middle East, Southeast Asia, Russia, Africa and other regions.

According to reports, in recent years, API6D oil pipeline valves and API6A wellhead equipment and tree valve products have been increasing year by year. Compliance with fire test and certification is a prerequisite for the smooth export of these valves. In previous years, the fire resistance test of valve products in Wenzhou area was only sent to the national valve and valve product quality supervision and inspection center in Hefei, Anhui Province. This has brought a lot of disadvantages to the export of the company's products, virtually extending the period of the product's fire test and certification. Affect delivery date.

In order to meet the urgent need of the company to conduct valve fire test and certification in Wenzhou, the Zhejiang Valve & Valve Center invested more than RMB 1 million in 2009 to establish a valve refractory laboratory. In July 2010, it obtained the National Laboratory CNAS accreditation certificate. The cooperation with TUV and DNV will further facilitate the local valve companies in Wenzhou.

Electrofusion Machine

Electrofusion welding is the name given to resistive implant welding of thermoplastic pipes. It is one of two main techniques used for the joining of polyethylene gas and water pipes. Electrofusion welding employs fittings that are placed around the joint to be welded. Metal coils are implanted into the fittings, and electric current is run through the coils to generate heat and melt part of the pipes, forming a joint upon solidification. There are two possible fittings used in electro fusion welding: couplers and tapping tees (electrofusion saddles). Electrofusion Machines/Electrofusion Welders are used for electrofusion fittings welding. Electrofusion Fittings are a heat treatment method compared to butt fusion methods and are used to generate heat. Electrofusion welding is a type of pipe welding and polyethylene fittings, in which there are special connections that have electrical resistance wire to create welding melting temperatures. The electric current is transmitted through the electrofusion welding eequipment and through the control box to the two ends of the connection. Yuda offers a fulll range of EF315 HDPE Electrofusion Welders, EF500 poly pipe electrofusion welding machine, EF630 HDPE Fitting Electrofusion Equipments and EF800 Electrofusion hdpe fittings machines
