Abstract
The utility model provides a carbon steel and stainless steel composite pipe, which is characterized in that the composite pipe is composed of a common carbon steel pipe and an inner lining stainless steel pipe. The utility model is suitable for the pipe below 273 mm. In order to satisfy the basic dynamic requirements, the total wall thickness of the composite pipe can be the standard size or nonstandard size and the wall thickness of the inner lining stainless steel pipe can be 1.0 to 2.5 mm. The common carbon steel pipe sheathed on the outer part can be a steel pipe without seams or a steel pipe with seams. The inner lining stainless steel pipe can also be the steel pipe without seams or the stainless steel pipe with seams. Under the condition that the utility model satisfies the basic dynamics requirements, the utility model has good corrosion resistance and low cost.
Description
The utility model relates to metal pipe, and a kind of carbon steel and stainless composite pipe are provided especially.
Metal pipe element is the common engineering element of industry extensive uses such as chemical industry, oil, be mainly used in the transmission of various flowing mediums, at some special flowing medium environment, under the etching condition as various acid, alkali, salt, material to metal pipe element has higher requirement, can adapt to the Stainless Steel Tube of varying environment as needs, thereby improve cost greatly.
The purpose of this utility model is to provide a kind of carbon steel and stainless steel composite pipe, and it is satisfying under the situation that basic mechanical requires, good corrosion resistance, and with low cost.
The utility model provides a kind of carbon steel and stainless steel composite pipe, it is characterized in that: this composite pipe is made of Ordinary Steel pipe (1) inner liner stainless steel pipe (2).
The utility model is applicable to the tubing that 273mm is following.In order to satisfy basic mechanics requirement, total wall thickness of composite pipe can be a size any standard or off-gauge, and the wall thickness of inner liner stainless steel pipe (2) should be between 1.0～2.5mm.
In the utility model, the Ordinary Steel pipe of overcoat can be that seamless steel pipe also can be a seamed steel pipe, and material can be 20# steel, 45# steel, A3 steel etc.
The Stainless Steel Tube of liner also can be gapless stainless steel tube or the seam Stainless Steel Tube is arranged in the utility model, and material can be selected the stainless steel of the trades mark such as 304,302,306 according to the different needs of aggressive medium for use.
Below by embodiment in detail the utility model is described in detail.
Accompanying drawing 1 is the cut-away view of carbon steel and stainless steel composite pipe.
Embodiment 1
