Abstract
The invention discloses a stainless steel-based connecting method of an epoxy resin steel-plastic clad pipe, and belongs to the technical field of pipe connection. The stainless steel-based connecting method of an epoxy resin steel-plastic clad pipe is a simple and corrosion-resistant pipe connecting method suitable for various pipe sizes. The stainless steel-based connecting method of an epoxy resin steel-plastic clad pipe comprises the following steps of 1, welding a stainless steel pipe on at least one end of a common carbon steel pipe, wherein diameters of the stainless steel pipe and the common carbon steel pipe are same, 2, orderly carrying out abrasive blasting, heating, coating, solidification and cooling to obtain an epoxy resin steel-plastic clad pipe. 3, conveying the epoxy resin steel-plastic clad pipe to a construction site, 4, welding two ends of the stainless steel pipes of the two epoxy resin steel-plastic clad pipes by a stainless steel welding rod so that the two epoxy resin steel-plastic clad pipes are connected together, and 5, repeating the steps 4 until the total length of the connected epoxy resin steel-plastic clad pipes reaches the requirement. The stainless steel-based connecting method of the epoxy resin steel-plastic clad pipe has simple operation processes, is convenient for construction and is suitable for being popularized in the anti-corrosion pipe connection field.
Description
Technical field
Epoxy resin steel-plastics composite pipe stainless steel connection method of the present invention belongs to pipe fitting interconnection technique field.
Background technology
Progress at full speed along with China's economy; Aseptic technic has played irreplaceable effect in every field such as oil, electric power, chemical industry, environmental protection, pharmacy, is bringing into play more and more important effect as a lateral of anticorrosion industry is anticorrosion in industrial or agricultural especially industrial circle.Outside connecting except traditional flange on the connected mode of anti-corrosion pipeline (comprising polyethylene coated steel pipe, polypropylene coating steel pipes, modified epoxy powder coating steel pipes); Welding manner is because withstand voltage height, advantage such as convenient, fast are the first-selections of each designing unit, construction team always; But two kinds of settling modes have appearred in the easy fragile corrosion-inhibiting coating of high temperature that welding is produced in view of the situation accordingly.
One, pipe ends is respectively reserved the welding protection section in anticorrosion process; Pipeline is transported to the job site; After welder's welding finishes; Get into pipeline by manual work the inwall after welding is carried out the preventing corrosion of repaired mouth coating, but this kind method has many limitation: 1, this kind technology only is applicable to the pipeline (DN450 following personnel can't get into pipe interior preventing corrosion of repaired mouth) of caliber more than DN450.Even 2 calibers get into also dangerous property DN450 the above persons,, very easily cause construction safety hidden danger because inner-walls of duct is narrow, sluggish in air circulation.
Two, use pipeline enlarging connector (applying for a patent by other companies); So owing to be to use cost high in the patented product engineering; And installation process is complicated, and this kind connector only is applicable to the pipeline of caliber below DN450, so can receive a lot of restrictions in the reality field of using.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical problem to be solved provides a kind of simple, anticorrosion, method of attachment of being applicable to various calibers.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: epoxy resin steel-plastics composite pipe stainless steel connection method, carry out according to following steps:
The first step is at least one port welding of ordinary carbon steel pipe stainless steel tube with diameter;
Second step, the weld of ordinary carbon steel pipe, ordinary carbon steel pipe and stainless steel tube is carried out sandblast, heating, coating, curing, process for cooling successively, process the epoxy resin steel-plastics composite pipe;
In the 3rd step, make a plurality of epoxy resin steel-plastics composite pipes by the method in the first two step, and transport the epoxy resin steel-plastics composite pipe that makes to job site;
In the 4th step, the port with the stainless steel tube of two sections described epoxy resin steel-plastics composite pipes of stainless steel electrode welding couples together two sections epoxy resin steel-plastics composite pipes;
The 5th step repeated for the 4th step, reached Len req up to the epoxy resin steel-plastics composite pipe that couples together.
The pipe range scope of described stainless steel tube is 50mm-800mm.
Described epoxy resin steel-plastics composite pipe available polyethylene coating steel pipes or polypropylene coating steel pipes substitute.
The present invention compares the beneficial effect that is had with prior art: through behind the soldering stainless steel connector of ordinary carbon steel pipe two ends, carrying out sandblast, heating, coating, curing, process for cooling more successively; Process the epoxy resin steel-plastics composite pipe; When connecting two sections epoxy resin steel-plastics composite pipes, directly use the port of the stainless steel tube of two sections epoxy resin steel-plastics composite pipes of stainless steel electrode welding to get final product; This connected mode is installed simple; Cost is low, favorable anti-corrosion effect, and can be applied in the pipeline of various calibers.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is the structural representation of an epoxy resin steel-plastics composite pipe among the present invention.
Fig. 2 is the connection sketch map of two epoxy resin steel-plastics composite pipes among the present invention.
Among the figure, 1 is the ordinary carbon steel pipe, and 2 is stainless steel tube.
The specific embodiment
