For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise body, the Stainless Steel Band that described body is rolled by spiral, hot rolled strip or cold-rolled strip form, the outer wall at Stainless Steel Band, hot rolled strip or the cold-rolled strip place of rolling is the perpendicular muscle of spiral, the perpendicular muscle of spiral place is provided with welding node, and the perpendicular muscle snap fastener of spiral place is provided with Sealing.
Its additional technical feature is: the thickness of described Stainless Steel Band, hot rolled strip or cold-rolled strip is 0.5---3.5mm;
The inside and outside surface of the body that described cold-rolled strip forms is provided with zinc coat;
the inside and outside surface of the body that described cold-rolled strip forms is provided with coating layer.
Spiral bar provided by the utility model strengthens stainless steel gas pipe, the Stainless Steel Band that body is rolled by spiral, hot rolled strip or cold-rolled strip form, the outer wall at Stainless Steel Band, hot rolled strip or the cold-rolled strip place of rolling is the perpendicular muscle of spiral, the perpendicular muscle of spiral place is provided with welding node, and the perpendicular muscle snap fastener of spiral place is provided with Sealing.During manufacture Stainless Steel Band, hot rolled strip or cold-rolled strip in advance rolling-forming are to be U-shaped limit on one side, be the shape of right angle side on one side, then by Stainless Steel Band, hot rolled strip or cold-rolled strip spiral roll, make right angle side snap in U-shaped limit, Stamping Steel Ribbon is placed in to the knuckle place on U-shaped limit simultaneously, and utilize and to roll wheel and be molded into and be integrated, be shaped to after tubing, Stainless Steel Band, the right angle side of the outer wall at hot rolled strip or the cold-rolled strip place of rolling snaps in U-shaped limit becomes the perpendicular muscle of spiral, for the perpendicular muscle of spiral, by welding, form welding node, form spiral and strengthen the perpendicular muscle of welding, welding node has also played the effect that strengthens muscle, Stamping Steel Ribbon compacting under the effect of mold pressing wheel, reach the effect of sealing.
spiral bar provided by the utility model strengthens stainless steel gas pipe and compares compared to common larger caliber seamless steel pipe, spiral welded pipe, ERW on market, body wall thickness obviously reduces, effectively saved material resources, the body wall thickness of this structural type is generally 0.5---3.5mm, existence due to the perpendicular muscle of outer wall spiral, greatly improved ring stiffness and the bearing strength of body, due to the existence of Sealing, the sealing effect of tubing has been improved.Spiral bar provided by the utility model strengthens stainless steel gas pipe and is made into after body with Stainless Steel Band, can meet the requirement of Corrosion Protection; With non-stainless steel materials such as hot rolled strip, cold-rolled strip, copper strips, aluminium strips, be made into after body, then carry out after antiseptic wearable coat processing, can meet requirement anticorrosion to body, wear-resisting property.
spiral bar provided by the utility model strengthens stainless steel gas pipe owing to adopting steel material as housing construction, has improved the intensity of tubing itself; Because thin-wall steel tube has adopted the structural type of structural walls stiffening rib, further increased ring stiffness and the burst strength of pipeline; The pipeline of this structural type is after plastic-coated is processed, improved Corrosion Protection, effectively saved material resources, can carry for lower pressure the media such as water and corrosive fluid, also can be for negative pressure line, be particularly suitable for the underground mine use pipeline that draws out methane; Structural walls thin-wall steel tube inwall adopts spray polyurea material, can carry the media such as slurry, lotion of variable grain diameter.Cost performance is largely increased.Spiral bar provided by the utility model strengthens stainless steel gas pipe and is specially adapted to negative pressure line and the lower malleation liquid line of bearing capacity, also can be used for barotropic gas delivery line.
