Spiral wound gasket is a type of semi-metallic gasket, rationally
designed to provide a high performance in use at high temperature
and pressure. It is equipped with an ample compressibility and an
increased demand has been seen in these years because of the merit
that a gasket seating stress can be controlled by an optimum
cmpression thickness. It tis widely used at process line and lines
handling heating medium in oil refineries and petrochmical plants
as well as steam processing lines in thermal power stations, atomic
power stations and vessels of steam turbined engines. It is made of
V,W preformed thin metal strip and a selected filler material which
are tightly and spirally wound together with only metal strip wound
in several folds and spot-welded at the beginning and the end of
winding.
1.No skill required when installing the gasket because a perfect
sealing can be assured only stressing
it to a certain sealing thickness(exampleL original
4.5mm thick gasket may be compressed 3.2~3.4
mm)
2. It withstands concident high temperature and high pressure and
stable sealability can be assured
even if the operating conditions should suddenly
be changed. It would not be broken nor cause
leakage even if it should receive heat
andpressure cycles or thermal stress.
3.No leakage has been experienced even at very low temperature.
4.It can be used not only on piping flanges but also on joints of
various machinery and equipments
by changing material of metal winding and filler or
adding centering device and ribs.
5. Machinery cost can be minimized by using the gasket because it
does not require fine surface finish
of flange.
6. It does not stick to flange faces and cleaning or exchange of
gasket is quite easy.
