The Spring Festival, the lunar new year, is the beginning of the year and the traditional festival. It is commonly known as new year, new year, new year’s day and so on. The Spring Festival has a long history, which evolved from the worship of praying for new year in ancient times. All things are

Welding flange   Welding flange is a very common flange, which is usually used under high pressure or some extreme environment. So this requires welding flange has very good performance, so as to ensure the reliability of the pipeline. The metal near the flange joint will produce some turbulence and corrosion, which needs to be

According to the connection form, butterfly valve can be divided into clip butterfly valve and flange butterfly valve. The difference between them is that the flange butterfly valve has its own flange. When it is installed, the flange at both ends of the valve and pipeline can be connected by bolts. The clip on butterfly

Butt welding flange: for flange and pipe welding, its structure is reasonable, the strength and rigidity are large, can withstand high temperature and high pressure and repeated bending and temperature fluctuation, the seal is reliable, the nominal pressure of 0.25 ~ 2.5MPa of the concave and convex sealing face of the flange. Butt welding flanges

1. standard GB/T14383–93, GB/T14383–2008, ASME B16.11, petrochemical standard SH3410, Ministry of chemical industry standard HG/T21634. According to the form, it can be divided into 45 degree socket elbow and 90 degree socket elbow. According to the form of pipe, it can be divided into socket elbow and threaded elbow. According to the standard, the specifications

Carbon steel elbow is resistant to air, steam, water and other weak corrosive media and acid, alkali, salt and other corrosive corrosive medium steel, also known as stainless acid resistant steel. In the power, mine, metallurgy and other industries of carbon steel, the delivery and output of materials are transported by close range and high pressure. The

In twenty-first Century, large flange is one of the main equipment in chemical and oil refining field. The carbon steel flange interface of pressure vessel is a necessary channel for huff and puff material, and is the interface for docking other facilities. The tightness of the sealing interface of the pressure vessel is guaranteed by every flange

When the flange is in use due to improper flange connection or excessive leaking in use, users do not panic. First of all, to check the leak location, the leakage area is usually very small due to the small gap between the stainless steel flange joints, so it is impossible to seal the leak by sealing the gap.

The integrity of flange connections is very important for conveying fluid piping systems. Whether it is the pipeline system transporting chemical medium (such as hydrocarbons) or the water supply pipeline, the leakage of the flange connection will cause serious environmental and economic effects, and may even bring huge potential safety hazards. If flanges are not
