The previous versions of this document and its superseded documents are as follows. ---First published in 1984 as GB 4662-1984; ---The first revision in.1993 was divided into parts and published, namely GB/T 4622.1-1993, GB/T 4622.2-1993, GB/T 4622.3-1993; the second revision in.2003; the third revision in.2009; ---This is the fourth revision.IntroductionSpiral wound gasket is a kind of sealing gasket commonly used in flange joints. Related GB/T 4622.1-2009 "Wound Gasket Classification", GB/T 4622.2-2008 "Wound Gasket Pipe Flange Gasket Dimensions", GB/T 4622.3-2007 "Wound Gasket Technology" The three standards of "Conditions for Operation" have been published for a long time. In the meantime, with the introduction of new materials for winding, some process quality requirements of gaskets are no longer available. To meet market demand, and the applicable pipe flange standards GB/T 9124.1 and GB/T 9124.2 have been revised twice, so the above three standard is necessary. In order to be compatible with the pipe flange standards GB/T 9124.1 and GB/T 9124.2, which are written in PN and Class series respectively, also To avoid the length of the document being too large, the standards for spiral wound gaskets are correspondingly written into two series, PN and Class. GB/T 4622 aims to establish the necessary requirements for the design, manufacture, performance and selection of spiral wound gaskets for pipe flanges. It is planned to be divided into two parts. composition. --- Part 1.PN series. Establish the classification, size and technical requirements of spiral wound gaskets for PN series pipe flanges. --- Part 2.Class series. Establish the classification, size and technical requirements of spiral wound gaskets for Class series pipe flanges. Spiral wound gasket for pipe flange Part 1.PN Series1 ScopeThis document specifies the type, code, size and technical requirements of spiral wound gaskets for pipe flanges marked with PN (hereinafter referred to as "gaskets"). requirements, inspection methods, inspection rules, markings, signs, ordering information, packaging and storage.
