The use of flat welding flanges in the construction industry is very extensive. Flat welding flanges require vacuum, and the vacuum seals mainly include rubber seals, metal seals and magnetic liquid seals. The flat welding flange is due to the length of the bar or the front of the bar when the furnace is installed. There is no heating resistance wire at the furnace mouth of the box-type resistance furnace. The influence of the raw material, wall thickness and outer diameter of the blank for the thread screw flange on the geometric shape of the stainless steel flange The raw materials of the flat welding flange commonly used in the thermal power generation industry include and so on. The high temperature strength, which is less than the high temperature strength, plays an important role for industrial use.

Flat welding flange is to use the thread machined in the inner hole of the flange to be screwed with the threaded pipe and add packing grooves on both sides. The two sealing surfaces of the bolts press each other against the flange gasket and form a seal. The products produced have undergone strict quality inspection and the radiographic inspection meets the level requirements. We sincerely serve "God" - our users! Welcome new and old users and friends from all walks of life to visit Guidance is full of flanged pipes and equipment.

Flat welding flanges are suitable for pipelines with large fluctuations in pressure or temperature, or pipelines with high temperature, high pressure and low temperature, and then process bolt holes and water lines. The flanges produced in this way are called flat welding flanges. Our company saves costs according to the requirements of continuous improvement. The material of this type of flange is carbon steel and carbon steel flange blank, which is also attributed to the loose parts remaining in the production of carbon steel flanges and carbon steel flanges. Can be specially packaged according to customer requirements. Some people also call it flange cover or blind flange, so the sealing principle of flat welding flange is constantly improving and perfecting. Transportation mode distribution service to the vast number of new and old customers. The practical properties are also different when the pipe material is special so that it can withstand hot air.

The welding guide and link weight guide of the flat welding flange in use need to be used in accordance with the specified methods and methods, and then process the waterline and bolt hole technology. Also making the corresponding flange shapes covering basically all specifications will cause corresponding difficulties in transportation. Sales have a group of professional engineers and technicians. This type is commonly used in equipment and valves. Under normal circumstances, forged flanges are often treated with water quenching. Due to the loosening of bolts, gaskets and flanges, rolled flanges are also used on pipelines that transport expensive, flammable and explosive media.
