In the technique scheme, described metal pipe crimping is the stainless steel pipe crimping.It is good to have heat resisting and pressure resisting, the characteristics of long service life.
In the technique scheme, described metal pipe crimping is an individual layer.
In the technique scheme, described metal pipe crimping is double-deck.
In the technique scheme, the wall thickness of described metal pipe crimping is 0.1~1.5mm, and different wall thickness is applicable to different pressure ranges.
In the technique scheme, the outer wall of described metal pipe crimping is provided with soft metal coating or soft metal paper tinsel layer.
In the technique scheme, the material of described coating or paper tinsel layer is silver or nickel.
Adopt soft metal materials such as silver or nickel to handle and form coating or paper tinsel layer, make seal ring have the advantage that microcosmic extends, compensates the microcosmic gully, can remedy the roughness on flanged surface surface etc., effectively prevent the generation that microcosmic leaks at the metallic coil tube-surface.
In the technique scheme, described metal pipe crimping is that metal layer rolls and forms, and rolls the equidistant spot welding of seam and connects.
In the technique scheme, described metal pipe crimping is that metal layer rolls and forms, and rolls seam and is positioned at a side that contacts with medium on the transversal median plane.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
(1) the utility model metallic packing ring adopts the structure of metal pipe crimping clad metal silk screen, and heat resisting and pressure resisting, compensation and rebound elasticity are better, and be safe in utilization, and can adjust elasticity more easily.
(2) the utility model metallic seal ring outer surface is formed with soft metal coating or paper tinsel layer, has the advantage that microcosmic extends, compensates the microcosmic gully, can remedy the roughness on flanged surface surface etc., effectively prevent the generation that microcosmic leaks, further optimize sealing of the present utility model.
(3) full in the metal pipe crimping of the utility model metallic packing ring have sealing medium, further optimizes heat resisting and pressure resisting of the present utility model and elasticity.
(4) the utility model processing technology is simple, and function admirable can be widely used in the sealing of pipeline pressure containers such as nuclear power generating equipment, air equipment, boats and ships, Petro-Chemical Machinery equipment or other kinds equipment, flange connections.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Referring to accompanying drawing 1~9, a kind of metallic packing ring comprises the metal pipe crimping 1 of hollow ring, is provided with wire gaze 2 in the metal pipe crimping cavity.
Metal pipe crimping 1 can be individual layer or bilayer, and its material can be the corrosion-resistant metal materials that cooperate the sealed medium chemical characteristics, to satisfy different medium usage requirements.In the present embodiment, the stainless steel that described metal pipe crimping 1 employing wall thickness is 0.1~1.5mm rolls and forms, and different wall thickness is applicable to different pressure ranges.
As preferably, the seam 4 that rolls of described metal pipe crimping 1 is positioned at a side that contacts with medium on the transversal median plane, and making fullly in the metal pipe crimping has sealing medium, further optimizes heat resisting and pressure resisting of the present utility model and elasticity.Seam crossing can connect by equidistant spot welding, certainly, also can connect or not connect by other modes.
Fig. 1~Fig. 8 has provided four kinds of embodiments' structural representation respectively.
Wherein, Fig. 1~Fig. 2 is embodiment one a structural representation, is illustrated as the internal diameter metallic packing ring, metal pipe crimping 1 roll the inboard that seam 4 is positioned at transversal median plane, seam crossing does not connect.
