It is a flange without a hole in the center, and the effect is the same as that of the welded head and the threaded cap, except that the blind flange and the threaded cap can be removed at any time, while the welded head cannot. The sealing surface of the stainless steel flange should be flat and clean, and the stainless steel flange will not produce corrosion, pitting, rust, and is not easy to be worn. Standard: There are many kinds, depending on what you need; Surface appearance: Generally, it is smoothed and smoothed after being wrapped with glue; the new mixing tank is generally translucent, if there are special requirements, add glue The starch changes the color of the appearance. Therefore, customers usually require cast flanges, because the material has been forged to increase the structure density and also enhance its pressure bearing capacity. Steam traps should be installed on the inlet side of the steam solenoid valve, and the nozzles should be inclined.

The abbreviation of flange is but this connection is only a part of the equipment, Such as the text between the flange and the water pump, it is not easy to call the water pump a flange part. It also has the disadvantages of working hours and high cost of auxiliary materials; scratches are difficult to remove: all pickling passivation, chemical corrosion or electrochemical corrosion will occur in the presence of corrosive media and rust, and cannot be removed because Scratch, welding spatter and carbon steel, spatter and other impurities adhering to the surface of stainless steel; then how to deal with the problem of stainless steel flange processing? Select blanking, after completion, enter the next process, and different workpieces of stainless steel enter the corresponding process according to the processing requirements. What are the characteristics of carbon steel elbows? Carbon steel elbows are connected by carbon steel elbows. The horizontal flange blind plate is a kind of blind plate cover that is open to the surrounding surface, and is used for installation in the open installation where the surrounding surface of the installation needs to be frequently opened.

There are many types of sealing surfaces, including full plane, protruding surface, surface, tenon and groove surface, and ring connection surface. So how to improve the welding quality of large-diameter flanges? The technical points to pay attention to include top calcining speed, top calcining pressure, and preheating time. Flange connections have tensile, compressive, torsional, and shear strengths, and should be used in accordance with certain specifications and methods for sealing pipe plugs. The abbreviation of the flange, the abbreviation of the flange, is just a general term, and usually refers to opening several holes for fixing on the periphery of a disc-like metal body for connecting other things. Stainless steel flange manufacturers must use 308LSi welding wire for bottoming, and stainless steel flange manufacturers must use 308LSi welding wire for bottoming, and use low current welding. Smaller ones such as valves Wait, are called flange parts.

In domestic and international standards, there are clear grade requirements for the compression resistance of stainless steel flanges, and stainless steel flanges are generally divided into. High pressure flanges are usually directional and cannot be reversed. The horizontal flange blind plate is a kind of clamp flange blind plate. The clamp flange blind plate is divided into two types: horizontal flange blind plate and vertical flange blind plate (vertical flange blind plate is A kind of blind cover that opens vertically upwards and is used for open installations that need to be frequently opened at the top of the installation. When installing a forged flange, we need to use a torque wrench to pre-tighten the bolts on it. The bolts are under tension. Under the conditions of stress and shear stress, the load it bears will be greatly reduced.

Because the welded elbow has many welds, its performance is not as good as that of the stamped elbow, and it is easy to be corroded and leaked. The flow direction of the medium is usually marked on the valve body, and the direction indicated by the sign should be consistent with the direction indicated by the sign. Among them, two kinds are commonly used. Strictly follow the welding technology welding. The main area of production is in the area. This thing is widely used in machinery, so it looks strange, as long as it looks like a flange, its name comes from English. Stainless steel flange manufacturers have a large number of non-metallic inclusions in the forging billet for manufacturing flanges. During the forging process, the volume-type inclusions are repeatedly forged and become area-type inclusions, which causes the forging along the inclusions to occur inside the material. Make cracks. After investigation, it was found that the intersection of Hongxia Street and Tongjiang Street, and the intersection of Zhenjiang Street and Chongjian Street were all in shallow water. Flanges processed by forged flanges and their gaskets and fasteners are collectively referred to as flange joints. My SH clamp flange blind plate products have been widely used in petroleum, chemical, natural gas and other industries.
