Problems solved by technology

In addition, due to the separation or gaps between the single-layer metal pipes, this kind of metal composite pipe is prone to wrinkles when the metal composite pipe is bent; during welding, quality problems such as warping deformation are likely to occur near the weld seam, so that The application range of metal composite pipe is limited

Embodiment 1

[0014] A kind of manufacturing method of brazed composite pipe of the present invention, can be in seamless carbon steel base pipe 1 inner composite stainless steel pipe 2; also can be in seamless carbon steel base pipe outer jacket composite stainless steel pipe; also can be in seamless A method for manufacturing a composite stainless steel tube inside a carbon steel base tube, and a composite stainless steel tube outside a seamless carbon steel base tube. The above stainless steel tube can also be a titanium alloy tube, and the manufacturing process is basically the same.

[0015] This embodiment is a method for manufacturing a brazed composite pipe with a stainless steel pipe 2 inside a seamless carbon steel base pipe 1, which is carried out in sequence as follows:

[0016] 1. The seamless carbon steel base pipe 1 and the stainless steel pipe 2 are respectively cut to length.

[0017] 2. Degrease, pickle and dry the seamless carbon steel base pipe and stainless steel pipe r...

Abstract

A soldering technology for manufacturing the composite metallic pipe includes coating the solder on the surface of each single metallic pipe, sleeving them together, drawing to swell them for closing to each other tightly, heating to 1100-1200 deg.c to smelt the solder, holding the temp for 2-10 min, and cooling. Its advantages are tight closing between pipe layers, no corrosion of residual dregs, dirt, air, water, etc. long service life and high bendability.

Description

technical field [0001] The invention relates to a method for manufacturing a metal pipe, especially a method for manufacturing a metal composite pipe. Background technique [0002] Existing metal composite pipes include double-layer metal composite pipes and multilayer metal composite pipes. The manufacturing method of the metal composite pipe adopts the mechanical composite method, firstly, the single-layer metal pipes are fitted together, and then the inner and outer walls of the metal pipes of each layer are bonded together by a mechanical drawing method. The metal composite pipe manufactured by the mechanical composite method is not tightly bonded between the single-layer metal pipes, and there are gaps, which form the separation of the single-layer metal pipes and generate interlayer spaces. When there is slag and dirt in the interlayer space, the slag and dirt will accelerate the corrosion of the metal composite pipe. Especially when the metal composite pipe is used ...
