Abstract
The utility model relates to a pipe joint whose surface is provided with a coating, which is applicable for pipes with path dimension of 15-200 mm. according to the technical scheme adopted by the utility model, a carbon steel pressurized pipe joint comprises a pipe body and a pipe orifice arranged on the end portion of the pipe body, wherein the pipe body and the pipe orifice are provided with channels. The pipe joint is characterized in that the inner surface and the outer surface of the pipe body and/or the pipe orifice are provided with coatings, wherein an expansion section which extends outwards is arranged in the pipe orifice, one end of the extension section is connected with the pipe body through an arc section in transition, and the other end thereof is an arc retractable section which shrinks inwards. The pipe joint can be convenient for installation and construction.
Description
Technical field
The utility model relates to the coated pipe joint in a kind of surface.Applicable scope is the pipe fitting of latus rectum size 15～200mm.
Background technique
Existing carbon steel tubing and joint (being commonly called as galvanized pipe and zinc-plated joint) are very wide in the application of aspects such as fire-fighting, water supply, conveying.Because the installation of this tubing is by being threaded, therefore, the wall thickness of carbon steel tubing and pipe joint will reach certain requirement could machining screw; The operation of tubing and pipe joint machining screw is finished in the erecting bed in addition, therefore needs certain space, so that machining screw, installation rate is slow, takes time and effort; Can meet the influence that some are subjected to installation environment in installation process, must replace being threaded with field welding, usually field welding is referred to as to get angry in project installation, getting angry exists potential safety hazard, and inconvenience is installed, so reality should be avoided in installing as far as possible.Typical tubing and joint are as described in the ZL99208089.4, and the surface of this tubing and joint does not have anticorrosive coat, in use is corroded easily; And, there is not changeover portion between the U-groove bevel of body end and body, mechanical property is poor.
Summary of the invention
The utility model purpose is the coated pipe joint in a kind of surface of design, to make things convenient for installation.
According to the technological scheme that the utility model provides, described carbon steel sealing pressure type pipe joint comprises body and is positioned at the mouth of pipe of body end that in the body and the mouth of pipe passage is arranged, it is characterized in that: the inner and outer surface at the described body and/or the mouth of pipe all is provided with coating.
One section extending section that expands outwardly extension is arranged in the described mouth of pipe, and an end of described extending section utilizes the arcuate segment transition to be connected with described body; The other end of described extending section is the arc contraction section that inwardly shrinks.
The minimum diameter of described arc contraction section approaches the internal diameter of body.
The enlarged portion of one section internal diameter greater than the internal diameter of body is set between the body and the mouth of pipe, and an end of described enlarged portion is connected with described arcuate segment, is the arc enlarged portion of one section expansion that stretches out between the other end of described enlarged portion and the body.
The utility model has the advantages that: 1, the tube wall thickness that is connected with pipe joint of the wall thickness of pipe joint all is that original wall thickness is over half; 2, the erecting bed is not required, install simple; 3, need not field welding, avoid getting angry; 4, energy-conservation, material-saving, environmental protection.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is installment state figure of the present utility model.
Embodiment
The coated pipe joint in described surface comprises body 3 and is positioned at the mouth of pipe of body 3 ends, and passage 2 is arranged in the body 3 and the mouth of pipe, at the inner and outer surface of the described body 3 and/or the mouth of pipe coating is set all.Coating 7 and serving 8 in described coating comprises, described coating all covers all surface of the body 3 and the mouth of pipe.Coating 7 is to prevent that pipe joint from getting rusty with the main effect of serving 8 in described.The main component of coating has a variety of, and general main component is a zinc.With zinc-plated is example, and its method has cold galvanizing, and hot galvanizing, vacuum are zinc-plated, vacuum zincizing, Dacroment or the like; Its composition has zinc chrome coating, Zinc-Nickel coating layer or the like.The composition thickness of interior coating 7 and serving 8 is determining the usability of pipe joint.The material of main part of pipe joint can be used 15#, 20#, Q235 etc.
For ease of processing and manufacturing, one section trumpet-shaped extending section 5 that expands outwardly extension can be arranged in the described mouth of pipe, an end of described extending section 5 utilizes arcuate segment 4 transition to be connected with described body 3; The other end of described extending section 5 is the arc contraction section 6 that inwardly shrinks; This structure can be improved the mechanical property of pipe joint simultaneously, reduces stress and concentrates.The minimum diameter of described arc contraction section 6 approaches the internal diameter of body 3.The enlarged portion 9 of one section internal diameter greater than the internal diameter of body 3 is set between the body 3 and the mouth of pipe, and an end of described enlarged portion 9 is connected with described arcuate segment 4, is the arc enlarged portion 1 of one section expansion that stretches out between the other end of described enlarged portion 9 and the body 3.So that being connected and installation of pipe joint and other pipe fitting.
10 is card compression moulds among Fig. 2, the 11st, and sealing ring, the 12nd, pipe fitting.
Claims (4)
