Abstract
A novel copper and steel composite pipe, a manufacturing method, application and a welded structure body is described herein. The novel copper and steel composite pipe includes a copper pipe and a steel pipe. The steel pipe includes a first end, a second end and a middle part. The copper pipe includes a first end and a second end. The length of the copper pipe is less than that of the steel pipe. The copper pipe and the steel pipe are sleeved. The distance from an end surface of the first end of the copper pipe to an end surface of the first end of the steel pipe is less than 10 mm. The second end of the copper pipe is positioned at the middle part of the steel pipe, and the copper pipe and the steel pipe are welded and connected in a way of melting base materials.
Claims9
A novel copper and steel composite pipe, comprising:
- a steel pipe comprising a first end, a second end, and a middle part;
- and
- a copper pipe comprising a first end and a second end, wherein the length of the copper pipe is less than that of the steel pipe, the copper pipe is partially or totally sleeved on the steel pipe, when the copper pipe is partially sleeved on the steel pipe, the distance from an end surface of the first end of the copper pipe to an end surface of the first end of the steel pipe is less than 10 mm, and the second end of the copper pipe is positioned at the middle part of the steel pipe;
- when the copper pipe is totally sleeved on the steel pipe, both the first end and the second end of the copper pipe are positioned at the middle part of the steel pipe;
- and the copper pipe and the steel pipe are welded and connected in a way of melting base materials,
- wherein the cooper pipe has a plurality of through slots or through holes in a sleeve joint region corresponding to the steel pipe, and the through slots or through holes are distributed along a circumferential direction of the copper pipe.
A welded structure body, comprising two novel copper and steel composite pipes, each of the novel copper and steel composite pipe, comprising:
- a steel pipe comprising a first end, a second end, and a middle part;
- and
- a copper pipe comprising a first end and a second end, wherein the length of the copper pipe is less than that of the steel pipe, the copper pipe is partially or totally sleeved on the steel pipe, when the copper pipe is partially sleeved on the steel pipe, the distance from an end surface of the first end of the copper pipe to an end surface of the first end of the steel pipe is less than 10 mm, and the second end of the copper pipe is positioned at the middle part of the steel pipe;
- when the copper pipe is totally sleeved on the steel pipe, both the first end and the second end of the copper pipe are positioned at the middle part of the steel pipe;
- and the copper pipe and the steel pipe are welded and connected in a way of melting base materials,
- wherein the copper pipe in one novel copper and steel composite pipe is partially or totally sleeved outside the steel pipe, the copper pipe in the other novel copper and steel composite pipe is partially or totally sleeved inside the steel pipe, the two novel copper and steel composite pipes are sleeved to enable the copper pipes in the two novel copper and steel composite pipes to correspond to each other, and the copper pipes in the two novel copper and steel composite pipes are welded and connected.
