Abstract
A thin-wall stainless steel spiral welded pipe with large diameter mainly solves the problem that the current stainless steel pipe is expensive and the nominal diameter is limited. The utility model is characterized in that: a stainless steel plate (1) is coiled into a pipe shape; the wall thickness of the stainless steel plate (1) and the nominal diameter of the coiled pipe are respectively 0.3-2.0 mm and 250-3000 mm. The utility model has the advantages of low price and non-limitation of nominal diameter.
Description
Technical field:
The utility model relates to used welded tube in gas, the liquid transfer line field, especially large-caliber thin-walled stainless steel spiral welded pipe.
Background technique:
In industrial production, because good, the long service life of stainless steel pipe antiseptic property particularly applies to drinking-water and transports on the pipeline, there is not secondary pollution, meet modern environmental requirement and generally adopted, but because heavy wall stainless steel pipe price height, make that it popularizes to use to be restricted; In addition, owing to be subjected to the restriction of stainless steel materials width, the nominal diameter of the thin-wall stainless steel tubing of vertical masonry joint moulding can't satisfy user's needs.
The model utility content:
In order to overcome the deficiency that existing stainless steel pipe price height and nominal diameter are restricted, the utility model provides a kind of large-caliber thin-walled stainless steel spiral welded pipe, this large-caliber thin-walled stainless steel spiral welded pipe is that stainless steel composite pipe has been widened application, has the low and unrestricted characteristics of nominal diameter of price.
The technical solution of the utility model is: this large-caliber thin-walled stainless steel spiral welded pipe comprises stainless steel materials, the stainless steel materials helix-coil is a tubulose, and the wall thickness of stainless steel materials and the nominal diameter that is rolled into Guan Houguan are respectively 0.3-2.0 millimeter and 250--3000 millimeter.
The utlity model has following beneficial effect: owing to take the stainless steel materials helix-coil in the such scheme is tubulose, its helix seam fills silk with argon arc and welds, because stainless steel materials is that helix-coil becomes tubulose, the nominal diameter that is processed to Guan Houguan is not limited by the raw material Dimensions; The wall thickness of stainless steel materials and nominal diameter are respectively 0.3-2.0 millimeter and 250--3000 millimeter, have saved raw material, and light being easy to installed, be easy to the processing of curling, processing cost is low, and Dimensions is suitable for producing needs, has also widened application for stainless steel composite pipe simultaneously.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model.
1-stainless steel materials among the figure, the 2-weld seam.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this large-caliber thin-walled stainless steel spiral welded pipe comprises stainless steel materials 1, stainless steel materials 1 helix-coil is a tubulose, its helix seam fills silk with argon arc and welds, because stainless steel materials 1 becomes tubulose for helix-coil, the nominal diameter that stainless steel materials 1 is processed to Guan Houguan is not limited by the raw material Dimensions, the weld seam 2 of stainless steel materials 1 fills silk by argon arc and is welded, rate of cooling is even during the joint close welding, reduce thermal stress, be out of shape very for a short time, guaranteed the regular of weld seam, strengthened weld strength, good corrosion resistance; The wall thickness of stainless steel materials 1 is the 0.3-2.0 millimeter, has saved raw material, and light being easy to installed, and is easy to the processing of curling, and processing cost is low; The nominal diameter of the pipe that stainless steel materials 1 is rolled into is the 250--3000 millimeter, and Dimensions is suitable for producing needs, has also widened application for stainless steel composite pipe simultaneously, is worth of widely use.
Claims (1)
