Gasket standards are the following: to the left to the right, | gasket standard GB/T 4622.1 - 2003 GB/T 4622.2 - Classification of spiral wound gasket 2003 spiral wound gaskets for pipe flanges size GB/T 4622.3 - 1993 GB/T 9126 specifications of spiral wound gaskets for pipe flanges - 2003 non metallic flat gasket size GB/T 9128 - 2003 steel preparation of metallic ring gasket for pipe flange size GB/T 9129 - 2003 non metallic flat gaskets for pipe flanges technical conditions of GB/T 9130 - 1988 steel pipe flange connection metallic ring gasket for technical conditions of GB/T 13403 - 1992 large diameter carbon steel pipe flanges with a gasket GB/T 13404 - 1992 pipe flanges polytetrafluoroethylene envelope gaskets for GB/T 14180 - 1993 winding the type of gasket testing method of GB/T 15601 - 1995 pipe flanges with metal cladding gasket GB/T 19066.1 - 2003 flexible graphite corrugated metal gasket branch GB/T 19066.2 - 2003 flexible graphite metal gaskets for pipe flange gasket size GB/T 19066.3 - 2003 flexible graphite metal gaskets specification GB/T 19675.1 - 2005 pipe flanges with metal punching plate flexible graphite composite gasket size GB/T 19675.2 - 2005 pipe flanges with metal punching plate flexible graphite composite gasket technology JB/T 87 - 1994 pipe flanges for asbestos rubber gaskets for JB/T 88 - 1994 pipeline flanges with metal serrated gasket JB/T 89 - 1994 pipe flange metallic ring gasket for JB/T 90 - 1994 pipe flange Spiralwound gasket for JB/T 6628 - 1993 flexible graphite composite (plate) pad JB/T 8559 - 1997 JB/T 4718 - 1992 metal gasket pipe shell type heat exchanger with metal gasket JB/T 4719 - 1992 for shell and tube heat exchangers gasket

Q:Installation requirements for gaskets

4, when sealing gasket is pressed, it is better to use torque wrench. For large bolts and high strength bolts, it is better to use hydraulic tightening devices. The tightening torque shall be calculated by calculation according to the given gasket. The size of the hydraulic pressure of the hydraulic tightening device shall also be determined by calculation.5. When installing the gasket, tighten the nut in sequence. However, the design value should not be screwed once. Generally should be recycled at least 2~3 times so that the gasket can be evenly distributed.6, the flammable and explosive medium pressure vessel and piping, replacing gasket should be used to avoid security tools, tool and flange bolts or collide, sparks, causing a fire or explosion accident.7, if there is leakage of the pipeline, it is necessary to reduce the pressure, then replace or adjust the installation of gasket, strictly prohibited with pressure operation.

Q:Can gb/t97.1 be used for sealing?

Can not. This is the washer used for the nut, not the gasket used for sealing.GB/T 97.1-2002 flat washer level aThis standard specifies the nominal specifications (thread diameter) for 1.6 ~ 64mm, standard series, hardness class 200HV and 300HV grade, product level is a class of flat washers.

Q:What is the function of the washer between the end cap and the case?

Buffer, the amount of thermal deformation reserved.

Q:Can the metal gasket face seal reach 100MPa?

The gasket standard is mainly the following: first, the standard GB/T 4622.1 - 2003 gasket spiral wound gasket classification GB/T 4622.2 - 2003 spiral wound gaskets for pipe flanges size GB/T 4622.3 - 1993 GB/T 9126 specifications of spiral wound gaskets for pipe flanges - 2003 non metallic flat gaskets size GB /T 9128 - 2003 steel pipe flanges with metal.

Q:Is there any prospect? Promising, which company in China to do this more professional?

Therefore, asbestos free products are very promising and promising. You can take a look at this company, Shanghai cord sealing materials Co., ltd..

Q:Are gaskets and gaskets the same thing?

The gasket, as its name suggests, is the gasket and has the function of sealing. Generally plastic or paper based.I hope this will help you

Q:Why don't gaskets use metal gaskets in general?

Gasket is a kind of machinery, equipment, pipes, as long as there is a fluid, that is, the use of sealed spare parts, the use of internal and external parts, sealing material.

Q:What is the function of the belt gasket in the water heater?

Widely used in fluid transport equipment, pumps, valves, pipes, containers and other seals.
