High neck flangeProducts used in boilers and pressure vessels, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbows, food and other industriesHigh neck flange refers to the high neck height, which improves the stiffness and bearing capacity of the flange.High neck flange: Compared with butt welding flange, the welding workload is large, the electrode consumption is high, and it cannot withstand high temperature and high pressure and repeated bending and temperature fluctuations, but it is more convenient to install on site, and the process of weld film flaw

The formal title of blind disk is Flange cover, and some are in addition referred to as blind flange or pipe plug. It is a flange barring a hole in the core and is used to seal the pipe opening. The attribute is the equal as that of the head and cap, barring that the blind seal is a detachable sealing device, and the seal of the head is now now now now no longer geared up to be opened again. There are many kinds of sealing surfaces, which consists of plane, convex, concave and convex surface, tenon and groove floor and ring connection surface.

Alloy flangesMetals for pipes and pipelines with special characteristicsAlloy flanges are also a material type for flanges.Different from ordinary 20#, Q235 and other carbon steel flanges, it is mainly used for pipes and pipelines with special characteristics, and is mostly used in high-temperature and high-pressure positions.

The butt welding flange is not easy to deform, seals well, is widely used, has the corresponding rigid and elastic requirements and reasonable butt welding thinning transition, the welding joint is far from the joint surface, and the joint surface is protected from welding temperature deformation, it adopts a more complex cough flare structure, which is suitable for pipelines with large fluctuations in pressure or temperature or pipelines with high temperature, high pressure and low temperature, and is generally used for the connection of pipelines and valves with PN greater than 2.5MPa, and i

Metal flanges are a common pipe connection component, usually made of metal materials, and their benefits and features include:High strength: The metal flange is made of metal material, which has high strength and pressure resistance, and is suitable for high pressure and high temperature environments.Corrosion resistance: Metal flanges usually have good corrosion resistance, which can resist the erosion of some corrosive media and prolong the service life.High temperature resistance: The metal flange can withstand the working conditions in a high-temperature environment and is not easy to def

There are two main systems of international pipe flange standards, namely the European pipe flange system represented by the German DIN (including the former Soviet Union) and the American pipe flange system represented by the American ANSI pipe flange. In addition to this, there are Japanese JIS pipe flanges, but they are generally only used for public works in petrochemical plants and have little international influence. The flanges of various countries are briefly introduced as follows:1. The European system represented by Germany and the former Soviet Union is flanged2.

Alloy flangesMetals for pipes and pipelines with specific characteristicsAlloy flanges are additionally a fabric kind for flanges.Different from everyday 20#, Q235 and different carbon metal flanges, it is usually used for pipes and pipelines with unique characteristics, and is usually used in high-temperature and high-pressure positions.

The butt welding flange is now no longer typical to deform, seals well, is especially used, has the corresponding rigid and elastic necessities and precise butt welding thinning transition, the welding joint is a extended way from the joint surface, and the joint flooring is blanketed from welding temperature deformation, it adopts a accelerated difficult cough flare structure, which is gorgeous for pipelines with huge fluctuations in stress or temperature or pipelines with immoderate 

Welded flangesParts the regional tubes are linked to every and each and each and each and each otherThe welded flange is the nearby the neighborhood the pipe is linked to every and each and every and each and every one-of-a-kind and is linked to the pipe end. There are holes on the welded flange, and the bolts make the two flanges tightly connected. Sealed with intermittent gaskets.

Socket welded flange is a commonly used pipe connection method, and its features and advantages include:Good fastening: The socket welding flange connects the pipe by welding, the weld is firm, the connection is tight, and it has good sealing performance.Strong compressive capacity: The welded connection method makes the socket welded flange can withstand large pressure, which is suitable for high-pressure pipeline system.Corrosion resistance: Reduced risk of corrosion and improved corrosion resistance of piping systems due to the elimination of contact parts such as threads due to welded conn

Socket welding flange refers to the flange that is inserted into the flange ring ladder at the end of the pipe and welded on the outside of the pipe. There are two types: with and without a neck. The flange with neck tube has good rigidity, small welding deformation and good sealing, and can be used for occasions with pressure of 1.0~10.0MPa. Type B flanges for containers are also socket welded flanges, which are used in situations with high sealing requirements.

1. Loose flanges can be divided into three forms: flat welded steel ring free flanges, plate flanging free flanges, and butt welded ring free flanges.2. The free flange is to use flanging, metal rings, etc. to put the flange on the pipe end, and the flange can go on the pipe end. The metallic ring or flange is the sealing surface, and the attribute of the flange is to compress them.

Socket welding flange refers to the flange that is inserted into the flange ring ladder at the furnish up of the pipe and welded on the out of doorways of the pipe. There are two types: with and barring a neck. The flange with neck tube has awesome rigidity, small welding deformation and applicable sealing, and can be used for things to do with stress of 1.0~10.0MPa. Type B flanges for containers are in addition socket welded flanges, which are used in stipulations with excessive sealing requirements.

Threaded flange refers to a flange that is linked to a pipe with the simply beneficial recommended beneficial useful resource of thread. When designing, it can be dealt with with free flanges. The accumulate is that no welding is required and the improved torque on the cylinder or pipe is very small when the flange is deformed. The draw limit decrease lower back is that the flange thickness is huge and the fee is higher.

Socket welded flange is a in many instances used pipe connection method, and its points and blessings include:Good fastening: The socket welding flange connects the pipe by means of welding, the weld is firm, the connection is tight, and it has desirable sealing performance.Strong compressive capacity: The welded connection technique makes the socket welded flange can face up to giant pressure, which is appropriate for high-pressure pipeline system.Corrosion resistance: Reduced danger of corrosion an
