With neck flat welding flange specifications Applications | Wan Hai brand pipe fittings (certified) | Luwan District flange

Wan Hai Hebei Mengcun pipe factory is the leading enterprises, the main variety, many types of flat, butt, loose, with neck flange, improved throughout the country and large flange surface construction method of product sales Remedy: Pressure Testing techniques commonly employed Pigging, the specific method is to use compressed air to drive the pig to make it run in the pipe, in order to achieve remove dirt and weld slag and other debris purposes, general This operation need to be 4-5 times. After the pressure test, due to the water in the pipeline is not easy to clean, it can only increase the cleaning frequency. In addition, the use of repeated soldering head in the ball at the close method is also problematic, while increasing the labor intensity of the workers, on the other hand repeat welding head also leads to much higher consumption of materials and construction costs. In response, the industry technician presents a quick and easy method of flat welding flange construction, this method uses a quick opening flange, this flange can achieve fast start fast on or off from the cylinder flange hook ring, ring cover, safety interlock mechanism, opening and closing mechanism, the boom and the short section and other components constituted by field tests in a number of gas pipeline projects, the ratio of repeated soldering head method can greatly improve efficiency , but also significantly reduce the construction costs of large flange. Large flange surface treatment is a necessary step, regardless of whether the customer requires RF welded flange 1.0MPA, we usually have in the flange surfaces coated with anti-rust oil to prevent rust and damage the product. But sometimes the thick steel welded flange machining, large flange surface need to do some very special treatment. For example, some customers have asked for a large flange surface spray, spray colors and strict requirements for the purpose of this requirement is beautiful, because this flange is generally used in public places, in addition to strong, Also on the appearance of a very high demand. Indeed, the flange spray after treatment looks very nice touch what felt very delicate, indeed greatly enhance the image of the product. But similar special handling large flange surface are rare, the most commonly used anti-rust treatment or just said. Hebei Wan Hai diameter plant location and convenient transportation in particular, the main plate flange, welded carbon steel flanges forging with neck, with neck, loose flange, I plant a number of production lines, the main national standard, American Standard, the subject of all kinds of flanges, product range, reasonable price, selling all over the country. Large flange means is beyond the state departments under the flange dimensions. Generally refers to more than the size of the flange DN2000. Such products are all welded product, no threading, threaded product specifications are frequently used to DN15-DN100 in. National flange standards GB maximum size / T9119-2010 standard among 0.25MPa to 1.6Mpa pressure is among the DN2000. 2.5MPa pressure to the standard that is the biggest of the DN800. Tall transmission tower is a vital lifeline quantity and power engineering facilities. Transmission tower in a variety of materials, the steel tower because of its superiority and more widely adopted. Currently there have been more than a dozen more than 100m across the rivers and lakes of the towering steel transmission towers. Thus, the study of the steel tower is becoming increasingly important. Large flange node is a very important steel tower is the main form of connection nodes. Mechanical properties and calculation methods by flange node has been an important research topic. Since rivers and lakes across the towering steel transmission tower height and large, load, and traditional forms of flange increasingly unable to meet the engineering needs. As the main structure of transmission towers, power transmission project is an important lifeline engineering. Its security is the basis for a large-scale regional power system reliability. The transmission tower of the node, as a guarantee of peace transmission force structure, force the situation is very complicated, key parts of the transmission tower structure. Tall transmission tower is usually divided into angle steel tower and steel tower, whose nodes with different forms of the rod cross-section presented different characteristics. For angle steel tower, its use of the gusset plate connecting node, the node board through the rod connected to each other in order to achieve the purpose of force transmission, so with neck flat welding flange specifications Applications | Wan Hai brand pipe fittings (certified) | Luwan District Flange Cangzhou Mengcun County, 000 by sea pipe factory.
