Abstract
The utility model discloses a PP-R (polypropylene random copolymer) copper tube which is composed of a copper inner tube and a PP-R outer tube arranged concentrically. A high temperature hot melt glue layer is arranged between the copper inner tube and the PP-R outer tube. The PP-R copper tube disclosed by the utility model adopts the one-step forming production technology, namely, the copper inner tube forming and PP-R outer tube extruding are carried out on the same production line, and the copper inner tube and the PP-R outer tube are bonded by using the high temperature hot melt glue. Compared with other composite copper tubes produced by using the secondary production technology, the PP-R copper tube has the advantages of high composite strength, difficult joint leakage and the like. The inner-layer coppers of the PP-R copper tube are connected in an argon arc welding manner, so that the welding strength is high; and an outer-layer plastic is better connected with a copper layer by using the water film lubricating technology before being extruded. In an application, as the inner tube of the PP-R copper tube is welded in a butting manner, the PP-R copper tube has the properties of high temperature resistance and high pressure resistance of a butt welding composite tube and is suitable for the heating demand of the existing high temperature heat radiator.
Description
Technical field
The utility model relates to the pipe technology field, particularly a kind of PP-R copper pipe.
Background technique
Traditional copper pipe has characteristics such as firm, corrosion-resistant, high temperature resistant, and owing to copperly itself have advantages such as antibiotic, and the pliability that has of copper pipe is fine in addition, so can be used in various heating and the water supply system.In the process of using copper pipe, also have very big defective, like the copper pipe selling at exorbitant prices, installation process intensity is big in addition, and copper pipe employing mechanical connection manner, the easy seepage in joint, thus limited being widely used of copper pipe.
The PP-R pipe adopts hot melt to connect on Placement, and attachment security is reliable, has good mounting characteristics.But PP-R in use can not satisfy the requirement of antibiotic pipeline, and also can't reach the level of metal tube in resistance to high temperature, and the intensity of tubing self does not reach the intensity of metallic conduit or composite pipe yet.
The model utility content
The utility model technical problem to be solved is existing copper pipe is managed existing problem with PP-R and provided a kind of and have that copper pipe is antibiotic, the high temperature high voltage resistant characteristic has the PP-R copper pipe that PP-R pipe ability hot melt is connected advantage.
The utility model technical problem to be solved can realize through following technological scheme:
A kind of PP-R copper pipe is made up of pipe and PP-R outer tube in the copper of concentric setting, is provided with the high temperature heat-fusing glue layer between pipe and the said PP-R outer tube in the said copper.
The PP-R copper pipe of the utility model adopts one-shot forming production technology, i.e. copper interior pipe moulding and PP-R outer tube are extruded on same production line and carried out, and it is bonding that interior pipe of copper and PP-R outer tube utilize the elevated temperature heat melten gel to carry out.Other complex class copper pipes that adopt secondary production technologies to produce of comparing, PP-R copper pipe have not advantage such as easy to leak of combined strength bination height, joint.PP-R copper pipe internal layer copper adopts inferior arc-welding to connect, and weld strength is high, before outer layer plastic is extruded, adopts the moisture film lubrication technology, and outer layer plastic and copper layer are better combined.In the use, because pipe adopts the docking mode welding in the PP-R copper pipe,, be fit to the demand of present high temperature heat sink heating so have the characteristic of butt welding composite pipe high temperature high voltage resistant.
Description of drawings
Fig. 1 is the axial sectional schematic diagram of the utility model PP-R copper pipe.
Fig. 2 is a radially sectional schematic diagram of the utility model PP-R copper pipe.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Referring to Fig. 1 and Fig. 2, a kind of PP-R copper pipe is made up of with PP-R outer tube 2 pipe 1 in the copper of concentric setting, is provided with high temperature heat-fusing glue layer 3 between pipe 1 and the PP-R outer tube 2 in the copper.
The PP-R copper pipe employing one-shot forming production technology of the utility model, i.e. copper interior pipe 1 moulding and PP-R outer tube 2 are extruded on same production line and are carried out, and it is bonding that interior pipe 1 of copper and PP-R outer tube 2 utilize elevated temperature heat melten gel 3 to carry out.Other complex class copper pipes that adopt secondary production technologies to produce of comparing, PP-R copper pipe have not advantage such as easy to leak of combined strength bination height, joint.PP-R copper pipe internal layer copper adopts inferior arc-welding to connect, and weld strength is high, before outer layer plastic is extruded, adopts the moisture film lubrication technology, and outer layer plastic and copper layer are better combined.In the use, because pipe adopts the docking mode welding in the PP-R copper pipe,, be fit to the demand of present high temperature heat sink heating so have the characteristic of butt welding composite pipe high temperature high voltage resistant.
