Abstract
The utility model relates to a stainless steel tube, and specifically relates to a duplex stainless steel tube, which comprises a hollow stainless steel tube body, wherein the inner wall of the tube body is coated with a zirconium oxide layer, and a skidproof groove array is arranged on the outer wall of the tube body along the length direction of the tube body. The duplex stainless steel tube provided by the utility model has the characteristics of high heat dissipation efficiency, skid resistance, good rigidity, corrosion resistance, high mechanical strength and the like.
Description
Technical field
The utility model relates to a kind of Stainless Steel Tube, specifically is a kind of duplex phase stainless tube.
Background technique
Understand according to the claimant, stainless steel pipe is the common engineering original paper of every profession and trade extensive use, be mainly used in the transmission of the flowing medium of various media, existing stainless steel tube wall is too thin, at some special flowing medium environment, under the etching condition as various acid, alkali, salt, the material of metal pipe element there is higher requirement, and at the bottom of its rigidity, bad mechanical strength; And be the aesthetic property of trying to achieve the Stainless Steel Tube appearance, can carry out polishing treatment usually, this is unfavorable for interfixing between the assembly when commercial Application.
The model utility content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of anti-skidding, corrosion-resistant, the duplex phase stainless tube of good rigidly.
In order to solve above technical problem, the utility model provides a kind of duplex phase stainless tube, comprise body, body is the duplex phase stainless tube of hollow, the inwall of body is provided with zirconia layer, and the body length direction is provided with for anti-skidding groove array in the outer wall upper edge of body, and this groove is in order to increase the body surface area, improve radiating efficiency and increase frictional force, can play good anti-slip effect.
The technological scheme that the utility model further limits is:
Further, aforesaid duplex phase stainless tube, each groove in the groove array are square, and evenly distribute.
Further, aforesaid duplex phase stainless tube, the wall thickness of body are 3.0～5.0mm.
Further, aforesaid duplex phase stainless tube, the thickness of zirconia layer are 0.01-0.03mm.
Further, aforesaid duplex phase stainless tube, body is the S32900 duplex phase stainless tube, the S32900 duplex phase stainless tube has comparatively excellent decay resistance and anticorrosion stress-resistant performance, is widely used in methanol synthesis reactor, the ammonium acrylate crystallizer, soda ash is produced in the POLYPROPYLENE GLYCOL cooling, be used for the seawater heat exchanger, systems such as oil carrier heating coil are the important component parts that guarantees and prolong equipment safety operation.
The beneficial effects of the utility model are: the utlity model has characteristics such as radiating efficiency height, anti-skidding, good rigidly, corrosion-resistant and mechanical strength height.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of duplex phase stainless tube that present embodiment provides, structure as shown in Figure 1, the two phase stainless steel body 1 that comprises hollow, body 1 is the S32900 duplex phase stainless tube, the wall thickness of body 1 is 3.0～5.0mm, and coating thickness on the inwall of body 1 is the zirconia layer 2 of 0.01-0.03mm, is provided with for anti-skidding groove battle array 3 at the outer wall upper edge of body 1 body length direction, each groove in the groove array 3 is square, and evenly distributes.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
