CN202032282U - Circular-cutting capillary copper tube - Google Patents

Abstract

The utility model relates to a circular-cutting capillary copper tube. The circular-cutting capillary copper tube is characterized in that tube ports at the two ends are flattened and sealed; and the rear end is flattened, and then a circular-cutting technology is utilized for cutting the outer tube wall to form a circular-cutting port, wherein the depth of the circular-cutting port is 1/4-1/2 of the tube wall, and the length of the circular-cutting port is more than 3/4 of the circumference of the tube. In the circular-cutting capillary copper tube, the tube ports at the two ends are flattened and sealed, the oxidation of the inner wall of the copper tube is effectively avoided, the phenomenon that the cleanness is over the standard is reduced, especially for tubes needing to be conveyed by a long distance, the two ends of the tube are provided with circular-cutting ports, the flattened tube ports can be easily broken off in the use process of the circular-cutting capillary copper tube, the tube wall is not deformed, and the diameters of the tube ports are not reduced, so that the use is greatly facilitated.

Description

The ring cutting capillary brass pipe

Technical field

The utility model relates to a kind of copper pipe, and particularly a kind of two ends mouth of pipe flattens sealing, makes things convenient for the user to block to be crushed the ring cutting capillary brass pipe of the mouth of pipe.

Background technique

Copper pipe is a building, one of field common used materials such as heat supply, and existing capillary brass pipe is subjected to humid air and effect of dust easily in long-distance transport, cause the copper pipe inner wall oxide, and turbidity test exceed standard.In addition, not too easy when blocking because of all there are the characteristics of the little thickness of pipe wall of caliber in capillary tube, can cause mouth of pipe undergauge and burr phenomena when blocking with capillary pipe wrench or cutting machine, the user must carry out secondary operations for this reason.

The model utility content

It is identical that the technical problem that the utility model solved provides a kind of and existing capillary brass pipe usability, but the ring cutting capillary brass pipe that its inner tube wall corrosion resistance and client's usability improve greatly.

The utlity model has following structure for solving above technical problem: described ring cutting capillary brass pipe comprises pipe shaft, flattens the mouth of pipe, rings cut.The pipe shaft two ends mouth of pipe flattens sealing and is processed into the flattening mouth of pipe, flattens mouth of pipe rear end and utilizes ring cutting technology cutting tube wall, forms rings cut, and the rings cut degree of depth is 1/4 to 1/2 of a pipe thickness, and the rings cut girth is more than 3/4 of girth of pipe.

Good effect of the present utility model is: take the two ends mouths of pipe to flatten sealing, avoided the copper pipe inner wall oxide effectively, alleviate the turbidity test phenomenon that exceeds standard, particularly need the tubing of long-distance transport; Its two ends are provided with rings cut, in use can get rid of flattening the mouth of pipe easily, and tube wall do not have distortion, the mouth of pipe does not have undergauge greatly convenient the use.

Embodiment

As shown in Figure 1 and Figure 2, described ring cutting capillary brass pipe comprises pipe shaft 1, rings cut 2, flattens the mouth of pipe 3.The pipe shaft 1 two ends mouth of pipe flattens sealing and is processed into the flattening mouth of pipe 3, utilizes the cutting of ring cutting technology to flatten the mouth of pipe 3 rear end tube walls 4, is processed into rings cut 2, and its degree of depth is 1/4 to 1/2 of tube wall 4 thickness, and rings cut 2 girths are more than 3/4 of pipe shaft 1 girth.

Claims (1)

1. ring cutting capillary brass pipe, it is characterized in that: structure comprises pipe shaft, flatten the mouth of pipe, rings cut, the described pipe shaft two ends mouth of pipe flattens sealing and is processed into the flattening mouth of pipe, flatten mouth of pipe rear end and have rings cut, the rings cut degree of depth is 1/4 to 1/2 of a pipe thickness, and rings cut length is more than 3/4 of girth of pipe.
