For achieving the above object, the technical solution adopted in the utility model is: a kind of stainless steel ring expansion formula connection pipe fitting of stamped, comprise body, flanged plate and seal ring, described flanged plate is inserted in body, described ring set on body, seal ring supported flange plate, described connection pipe fitting two ends are provided with identical connection pipe fitting, be provided with bending body, weld ell between described connection pipe fitting and the bending body in the middle of the connection pipe fitting of two ends.
The stainless steel ring expansion formula connection pipe fitting of described a kind of stamped, its flanged plate one end are provided with joint socket in the lower flange.
The stainless steel ring expansion formula connection pipe fitting of described a kind of stamped, its connection pipe fitting is provided with circular weld.
The stainless steel ring expansion formula connection pipe fitting of described a kind of stamped, its connection pipe fitting one end is provided with the pipe bell end.
The stainless steel ring expansion formula connection pipe fitting of described a kind of stamped, its flanged plate fixing device is a hex head bolt.
The method of making this stainless steel connection pipe fitting is:
Step 1: get a stainless-steel pipe, size is cut out pipe according to the rules.
Step 2: will cut out good stainless-steel pipe and be put on the peculiar fixed mould, stainless-steel pipe is fixed.
Step 3: the stainless-steel pipe that fixes on peculiar fixed mould is at specific special device extrusion moulding.
Step 4: again to the stainless-steel pipe deep processing finished product of extrusion moulding.Specifically, be exactly to utilize existing tubular body, force material deformation through peculiar (different specifications) mould and special device, the process of distortion reaches specific shape.
The method advantage of making this stainless steel connection pipe fitting is: shorten manufacturing a finished product the cycle, enhance productivity, reduce toxic emission, environmental protection standard improves; Improve product percent of pass, reduce reject rate; Reduce cost of production, meet the need of market.
This stainless steel ring expansion formula connection pipe fitting can guarantee sealability, seal ring supported flange plate, make this stainless steel connection pipe fitting sealing effect highly significant, the inwall engaging surface that connection pipe fitting is close in the seal ring expansion forms flexible sealing, because of sealing material has plasticity, under the external force effect of distortion back, also can keep good sealing effect.
This stainless steel ring expansion formula connection pipe fitting body portion becomes the bending structure, helps the raising of the sealability of connection pipe fitting like this.
