The utility model discloses a stainless steel tube structural strength is high, not easy slipping roll when placing, and corrosion resistance is good simultaneously.
Description
Technical field
This utility model is related to pipe fitting technical field, more particularly, to a kind of stainless steel tube.
Background technology
Existing stainless steel tube can be divided into pipe and special pipe by transverse shape.Special pipe has rectangular tube, rhumbatron, ellipse
Pipe, from all directions six square tubes, pipe and the asymmetric pipe of various sections etc..Compared with pipe, special pipe typically has larger inertia
Square and modulus of section, have larger bending resistance, anti-twisting property.And the wall thickness more and more thinner of existing stainless steel tube, structure is strong
Degree declines, and security performance causes anxiety；Pipe easily skids in laying or placement rolling, brings inconvenience to construction；Daily life
Stainless steel tube, can very due to the presence of chloride ion in use environment, such as Sal, antiperspirant mark, sea water, Caulis Piperis Kadsurae, soil etc.
Fast to corrode, corrosion rate is even more than common mild steel, need to improve.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of stainless steel tube, structural strength
Height, being difficult to skid during placement rolls, while good corrosion resistance.
To reach above-mentioned purpose, the technical solution of the utility model is：A kind of stainless steel tube, including the section of both ends open
For circular body, the two ends of the body are equipped with external screw thread and female thread, and the outer wall of body is located at the external screw thread at two ends
Between it is circumferential uniform multiple along its axially extending raised line, two neighboring raised line is respectively from the external screw thread at two ends in body
Between place extend and beyond the middle of body, the inwall of the body is provided with nicr layer, and the outer wall of body is provided with antirust coat.
The section of the raised line is to clip a part of circle, and the center of circle of raised line is located on the outer wall of body, the half of raised line
Footpath is equal to the wall thickness of body.
The section of the raised line is to clip a part of ellipse, and the center of circle of raised line is located on the outer wall of body, raised line
2 times for the wall thickness of body of the length of major axis, the length of the short axle of raised line is equal with the wall thickness of body, the peak of raised line
For one of end points of major axis.
The beneficial effects of the utility model are：By the raised line being in staggered distribution between the external screw thread at two ends, greatly reinforce
Structural strength of the present utility model, while can play a part of to prevent from skidding in laying or placement；Nicr layer and antirust are applied
Layer can improve decay resistance of the present utility model.
Description of the drawings
Fig. 1 is the axonometric chart of embodiment of the present utility model 1；
Side views of the Fig. 2 for embodiment 1；
Side views of the Fig. 3 for embodiment 2.
In figure：Body 1, raised line 2, external screw thread 3, female thread 4.
Specific embodiment
Below by embodiment, and accompanying drawing is combined, the technical solution of the utility model is described in further detail.
Embodiment 1：
As shown in Figure 1 and Figure 2, a kind of section of stainless steel tube, including both ends open is circular body 1, the body
1 two ends are equipped with external screw thread 3 and female thread 4, i.e. the outer wall end of body 1 sets external screw thread 3, and the inwall end of body 1 sets interior
Screw thread 4 so that this utility model has inside and outside two kinds different installations to select.
The outer wall of body 1 is located at circumferential uniform multiple along its axially extending raised line 2, this reality between the external screw thread 3 at two ends
Be 16 with the quantity of the raised line 2 in new, two neighboring raised line 2 respectively from middle from the external screw thread 3 at two ends to body 1
Extend and beyond the middle of body 1, it can also be seen that really one raised line 2 is near one end of body 1 from Fig. 1
Start to extend to the middle part more than body 1 at external screw thread 3, another adjacent raised line 2 is near the another of body 1
Start to extend to the middle part more than body 1 at the external screw thread 3 at end, two neighboring raised line 2 is in the middle part of body 1
Locate some to be oppositely arranged, can play a part of to prevent from skidding in laying or placement, while material is saved, significantly
Structural strength of the present utility model is strengthened, has larger bending resistance, anti-twisting property, raised line 2 and body 1 to be formed in one.
The inwall of the body 1 is provided with nicr layer, and the outer wall of body 1 is provided with antirust coat.Nicr layer can using spraying plating,
The method such as deposition or High temperature diffusion is coated in 1 inwall of body and plays erosion-resisting effect, and antirust coat adopts iron oxide red antirusting paint,
Adhesive force is good, can form the paint film of densification to prevent the intrusion of corrosive substance, antirust coat from being also coated with simultaneously in 1 outer wall of body
On raised line 2.
The section of the raised line 2 is to clip a part of circle, and the center of circle of raised line 2 is located on the outer wall of body 1, raised line 2
Radius be equal to the wall thickness of body 1, the raised line 2 of the design will not be damaged to workmen, the circular cross-section of raised line 2
Truncated part is substantially and is overlapped with body 1, and the raised line 2 is reasonable in design so that overall structure is protected, using smoothly.
Embodiment 2：
As shown in figure 3, the cross sectional shape for differing only in raised line 2 with embodiment 1, the section of the raised line 2 is to clip
The ellipse of a part, the center of circle of raised line 2 are located on the outer wall of body 1, and the length of the major axis of raised line 2 is the wall thickness of body 1
2 times, the length of the short axle of raised line 2 is equal with the wall thickness of body 1, the one of end points of the peak of raised line 2 for major axis,
The raised line 2 of oval transition will not be damaged to workmen, the truncated part of the elliptic cross-section of raised line 2 be substantially with
Body 1 overlaps, and the raised line 2 is reasonable in design so that overall construction intensity is high, and workmen is difficult to skid in construction usage.
The foregoing is only this utility model preferably specific embodiment, but protection domain of the present utility model not office
It is limited to this, any those familiar with the art can be readily occurred in the technical scope that this utility model is disclosed
Change or replacement, should all cover within protection domain of the present utility model.
