Metal ring gasket is sealed pressure pipe flange ,an applied to oil
and gas pressure vessel, submarine, high-speed joint surface, high
temperature and high pressure valve cover joint.There are a variety
of materials and in a form suitable for the different design and
operational requirements, completely compliance with ANSI B16.20.
In the new flat type grooved flange, the common black iron,
stainless steel elliptical(Oval) and the octagonal can be used
interchangeably. the company can in the most short period of
delivery.
Note: the metal ring material hardness selected should be lower
than 15~20 HB flange, and the old product is not recommended for
repeated use, because the material hardening and damage may occur
and the flange or the sealing performance.
Hollow metal O - ring is made of high temperature resistant and no
corrosion of stainless steel tube production. It could make holes
in the inner or outer of the hollow metal o ring, when the pressure
goes up,that self sealing function will work. The o ring with the
small holes of the ring, especially the application of pressure
over 70kgf/cm ², it can handle more pressure than the basic O type
ring. The hollow metal ring based on customer needs, as PTFE plated
or silver plating and surface.

Corrugated metal is covered with graphite, ceramic or PTFE layer's. An additional finishing layer is applied depending on the requirements of the medium to be sealed. Such gaskets are used on uneven or distorted sealing surfaces, where more elastic materials with better sealing performance are needed.
Note: The metal is 0.5 mm thick and the corrugation pitch is 3mm, 4mm or 6mm depending on the width of the gaskets. The thickness of corrugation is approx. 1mm to 1,5mm, depending on gasket size. Corrugated metal can be covered with graphite, ceramic or PTFE layers in thickness 0.5mm, 1mm or 1,5mm.
