| Our company is produces the high, middle and low compressed steel pipe fittings, the flange series product specialized factory.After the surrounding area symbolized the authentication group limited company does authenticate, who manages the system to conform to GB/T19001-2000 idt ISO90001:2000 sign to request, and obtains the People's Republic of China country quality surveillance to examine the quarantine bureau pressure piping special equipment manufacture permit.This company produces fitting: 1997 to 2005 after Country Engineering supervision Bureau, the Ministry of Labor boiler pressure test center, the Hebei Province product quality supervises unit's and so on examination center surveillance spot-checks, the qualified rate 100%.φ25-φ426mm the cold draw Three Contacts self-restraint formation, in 1994 is evaluated the North China third session of technology trade fair gold medal.φ25-426 the stainless steel pushes the system bend, in December, 1993 is designed by the Chinese Petrochemistry Main corporation tubing the central station inspection examination to have to recommend for Chinese Petroleum Chemical industry Main corporation Project Ministry of construction the product; Pushes the system bend, the cold draw Three Contacts, the tapered pipe, the flange, the big aperture butt welding bend, for the Chinese petroleum natural gas (group) the main corporation level supply network member, and is integrated by the national electric power fitting center the network member unit.This company φ820 hydraulic pressure intermediate frequency pushes the system φ820×60 alloy bend, the hydraulic pressure intermediate frequency pipe bending machine may simmer makes the 1020mm elbow piece.
In order to fill the domestic stainless steel narrow tube and the swan neck endophragm throws the none remaining difficult blank, in 2000 our company has introduced the liquid buffing machine equipment and the advanced technology from Europe, Daqing builds up the decompose company in 2004 to gather in the splendid alkene project, our company throws the endophragm none remaining stainless tube one batch for it, in which thinnest endophragm only then 8mm, precision RMS63, the project begins for more than a year, in the pipeline gathers the splendid alkene to stick the material movement to be extremely unimpeded, has not had one time the phenomenon which shuts down because of the pipeline jamming, creates the very big benefit for the country.In 2006 our company gathers the splendid thin project for Dalian Petrochemistry Subsidiary company to throw the none remaining stainless steel pipe one batch, precision RMS125, RMS63, causes the operation to move the disposable success, for many years our company's fine polishing technology obtained user's praise and the high praise.
