GB/T 4622.2-2003 Dimensions of gaskets for spiral wound gasket pipe flanges
Some standard content:
GB/T4622-2003 has made some changes to the standard name and changed the original name " The "small series of quick-release gaskets" was modified to "small series of quick-release gaskets", and the "size of quick-release gaskets for use in pipes" was added in the "IS7005 pipe method" and the "size of quick-release gaskets for use in pipes" was expanded to "size of quick-release gaskets for use in pipes" in the first chapter. This part was implemented on the same day. The warning G/T4122.1993 was issued. This part was proposed by the China Machinery Industry Federation. This part is the National Technical Committee for Standardization of International Parts. Drafting units of this part: Mechanical Science Research Institute, Gonghai Xinfumi Technology Co., Ltd., Wuxi City General Chemical Co., Ltd., Dongguan University of Technology, Jianghua Hongwei Sealing Components Factory,
This part is drafted by: Ben Chuanying, Liu Zhengtan, Li Zhongyun, Xie Suting, Zhang Tongcheng, Chen Lin. This part was first issued in 1998: the first revision in 1991; the second subscription in 2003. 1 Specifications
Wound gaskets
Gasket dimensions for pipe flanges
This part specifies the types and dimensions of cable-wound gaskets for pipe flanges. This part applies to flanges with a nominal pressure of TN1.0--PN26.CMPa. 2 Normative references

The clauses in the following documents become clauses of this Part through reference in GT/T4522. However, they are valid references. All subsequent amendments (excluding errors) shall not apply to this Part. The parties to the conclusion or agreement of this Part shall study whether the latest versions of these documents can be used. For any undated referenced documents, the latest versions shall apply to this Part.
GB/T4622.1 Classification of gaskets
GB/T4622.3 Technical conditions for single-piece gaskets 3 Whole piece type
The gasket should be one of the following types:
a) Basic type
b) Inner ring
C) With positioning ring:
Inner ring and positioning ring are also included.
Figure 1 shows the type of gasket. Typical structure of the gasket. For flat or wide face flanges, the design should be modified to meet the requirements of the fixed ring specified in Table 3. The spacing between the sealing element and the locating ring should ensure that the element will not fall off the gasket during normal operation. Method: The shape of the gasket strip can be selected by the manufacturer. Note 2. The gasket material can be used as a universal component. The manufacturer is responsible for the detailed description of the gasket material in the price list/order form. 1. Working conditions, plastics manufacturer diameter Www.bzxZ.net

4 and flange rate sealing Applicable wall type 4.1 For flat (ET type) or raised face (RF type) flanges, the flanges for flat or raised face methods should be equipped with locating rings as much as possible. The flanges for PN6.?MPa and PN5.4MPa and above can be modified with PTFE (PTFE) material. The two types of gaskets applicable to flat (FF type) and raised face (RF type) methods are shown in Figure 2. Note: For flanges of PN3.C.PV3.5, P4.C and P5.VP, the flanges with internal rings V1, nN1, FMI can only be equipped with internal pressure, and the flanges with internal pressure and internal pressure are equipped with locating seals. Figure 2 Gaskets for flat and raised face flanges 4.2 For flanges with concave and convex faces (MF type) The flanges with internal pressure should be equipped with internal rings. 4.3 For use in the world (TG type 1 flange
