Abstract
The utility model relates to a water supply plastic -lined composite galvanized steel pipe, including galvanized steel pipe, its characterized in that: still include the inside lining plastic tubing even system has the trachytic texture rather than integrated into one piece on the outer wall of inside lining plastic tubing, the inner wall of inside lining plastic tubing through wrap -around hot melt adhesive on its outer wall and galvanized steel pipe glue together and be connected, the hot melt adhesive fill between the trachytic texture of inside lining plastic tubing and galvanized steel pipe's inner wall. The utility model discloses structural design scientific and reasonable has anticorrosive, long service life, can guarantees the drinking water quality, carries advantage smooth and easy, that the hot and cold water homoenergetic uses, is a water supply plastic -lined composite galvanized steel pipe who has higher novelty.
Description
Technical field
This utility model relates to a kind of water supply steel tube, and particularly a kind of feedwater lining moulds compound coating steel pipe.
Background technology
Coating steel pipe is because its outer surface is corrosion-resistant, service life is long, therefore is widely used in the field such as plumbing, conveying gas.For feedwater field, owing to drinking water to be carried by the pipeline that this coating steel pipe is formed, drinking water directly contacts with tube wall, and long-time tube wall can get rusty, corrode, and shortens its service life；And, anvil cinder is mixed in drinking water the quality that also can affect drinking water.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of has that design science is reasonable, anticorrosive, length in service life, ensure that the feedwater lining of quality of drinking water moulds compound coating steel pipe.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of feedwater lining moulds compound coating steel pipe, including coating steel pipe, it is characterized in that: also include inner lining plastic tube, the outer wall of described inner lining plastic tube is uniformly shaped with trachytic texture integrated with it, described inner lining plastic tube is connected with the inwall gluing of coating steel pipe by the PUR of cladding on its outer wall, and described PUR is filled between the trachytic texture of inner lining plastic tube and the inwall of coating steel pipe.
And, described trachytic texture is the decorative pattern or groove arranged on the outer wall of inner lining plastic tube or protruding or that transverse and longitudinal is staggered muscle.
And, described coating steel pipe is hot galvanized steel pipe.
And, described inner lining plastic tube is polythene material or refractory polyethylene material.
Advantage of the present utility model and good effect be:
1. this feedwater lining moulds compound coating steel pipe, by increasing by a plastic tube on the inwall of original coating steel pipe, this plastic tube is fitted tightly by the inwall of PUR with coating steel pipe, owing to the outer wall of inner lining plastic tube is matsurface, in the gap that its inwall with coating steel pipe is formed after filling PUR, resistance between matsurface and PUR increases, make that the two combines is more firm, avoid inner lining plastic tube to separate with PUR, the whole steel pipe that meets is made to have connection fastening, resistance to corrosion is strong, extend pipeline service life, the advantage that ensure that quality of drinking water；Further, the inner wall smooth of vinyl tube, it is possible to reduce the drinking water resistance when conveying, reduce power consumption.
2. this feedwater lining moulds compound coating steel pipe, is damaged by the burn into selecting hot galvanized steel pipe to avoid outer surface of steel tube, it is ensured that its service life.
3. this feedwater lining is moulded compound coating steel pipe and is divided into cold water pipe and hot-water line, meets the different demands of user.The liner of cold water pipe uses polyethylene (PE) material, and the plastic tube of this material can carry the fluid of less than 60 DEG C；The liner of hot-water line uses refractory polyethylene (PE-RT) material, and the plastic tube of this material can carry the fluid between 90 DEG C-95 DEG C.
4. this utility model scientific structure design is reasonable, has anticorrosive, length in service life, ensure that quality of drinking water, carries the advantage that smooth and easy, hot and cold water all can use, and is that a kind of feedwater with higher innovation serves as a contrast and moulds compound coating steel pipe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1-coating steel pipe, 2-PUR, 3-trachytic texture, 4-inner lining plastic tube.
Detailed description of the invention
Below in conjunction with the accompanying drawings, by specific embodiment, the utility model is described in further detail.Following example are illustrative, are not determinate, it is impossible to limit protection domain of the present utility model with this.
A kind of feedwater lining moulds compound coating steel pipe, including hot galvanized steel pipe 1, its innovation is: also include inner lining plastic tube 4, the outer wall of described inner lining plastic tube is uniformly shaped with trachytic texture 3 integrated with it, described inner lining plastic tube is connected with the inwall gluing of coating steel pipe by the PUR 2 of cladding on its outer wall, and described PUR is filled between the trachytic texture of inner lining plastic tube and the inwall of coating steel pipe.Described trachytic texture is the muscle that the transverse and longitudinal arranged on the outer wall of inner lining plastic tube is staggered.
Described inner lining plastic tube is polyethylene (PE) material or refractory polyethylene (PE-RT) material.
This feedwater lining moulds the production technology of compound coating steel pipe:
1. (1) polyethylene pellet and color masterbatch are stirred colour mixture by plastic drying blending machine by the production that lining is moulded；(2) the extrusion that the raw material of colour mixture carries out tubing by single screw extrusion machine being processed, now, due to the effect of different decorative pattern extruder heads, the outer surface at tubing forms the matsurface of different structure；(3) the tubing of extrusion is coated with PUR by PUR coating machine on the matsurface of tubing；(4) cool down molding.
2. (1) the coating steel pipe bought is carried out defluxing muscle process on continuous way steel pipe inner wall datatron by the process of coating steel pipe；(2) utilize machine for cleaning inner wall of steel tube the cleaning waste slag that upper not operation produces to be fallen.
3. molded (1) utilization of steel is moulded pipe and is drawn in machine and moulded by the lining processed inside the coating steel pipe just installing to handle well；(2) being heated and mould lining to suppress by steel pipe makes it expand, and the lining of expansion is moulded and made its surface coated PUR melt after running into the heat of steel pipe, is cooled to sizing after lining is moulded and is connected with steel pipe gluing.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: without departing from this utility model and spirit and scope of the appended claims, various replacements, to change and modifications be all possible, therefore, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
