Large-diameter flange manufacturer rolled 7 * 24-hour technical advice hotline, you still choose a large-diameter flange manufacturer and worry about it, Hebei Province in North China and Thailand Billiton is a large professional manufacturer of carbon steel flanges, the company for many years has always insisted: anxious customers, clients would like to think of philosophy to get the majority of customers praise and recognition, has signed a long-term supply agreements with a number of large-scale projects, hand-Thai Tinto let us create grand Albert Give drainage of large diameter flange rolled plate cut into planks, then roll into a circle. reprocessing waterline, bolt holes, etc. This is generally large diameter flange roll, maximum 8 meters can be done. Such rolled flanges have a good quality assurance. Because the raw material is in the board, good density. Materials are carbon steel, stainless steel, alloy steel. In the machinery industry, many manufacturers use rolled flange (also can be said to strengthen the ring) is connected to or supporting role, and so as, so you can use steel (flat) directly on the roll flange roll device directly into needed to ring, this provincial labor and materials processing methods, significant savings flange costs. Rolled carbon steel flange theoretical weight algorithm: 1. first with (OD - ID) divided by 2 get out results. 2. then (OD - results above), after multiplying the result X0.02466X thickness above 3. After the above two steps, you come to the theoretical weight of the flange rolled carbon steel. If the situation with the production segment, you can do 12 meters -15 meters or larger size. Such flanges have a good quality assurance. Because the raw material is in the board, good density. Rolled flange welding process at the interface is the most important, to do X-ray film detection processing. Interface well, the entire flange material would be no problem. During machining the bolt holes, is not allowed to have the weld bolt hit the place. Such flanges are made of carbon steel, stainless steel, alloy steel. Production bases in Hebei Mengcun County area. Pipe Co., Ltd. Hebei Wanrun which can produce products to seven meters. 3 m above the rolled flange at the signing of the contract, we should first take into account the problem of transportation. Because of the highway overpass height limit is 4.5 meters. The height of the transport car trunk is about 1.5 meters, plus the height of the flange on the ultra-high. The ultra wide flange rolled to the local traffic management departments can apply for large transport. But large transport costs are too high, it is recommended that the production segment, to the site to install.
