Abstract
The utility model discloses an interior porcelain enamel steel butt welding pipe fitting, which comprises a pipe fitting body. The port of the pipe fitting body is provided with a stainless steel pipe. The inner surfaces of the pipe fitting body and the stainless steel pipe are provided with a porcelain enamel layer. The pipe fitting body and the stainless steel pipe are connected into one body in a butt welding manner. The external surfaces of the pipe fitting body and the stainless steel pipe are provided with an antisepsis layer. The porcelain enamel layer is formed by sintering glaze slip. The antisepsis layer is a PE antisepsis layer and is a radiation cross linking PE hot shrinkable tape. The utility model has the advantages of simple structure and convenient implement. The utility model not only ensures the antisepsis performance of the butt welding pipe fitting but also makes the best of the resources and effectively reduces the manufacture cost of products.
Description
Technical field
The utility model relates to a kind of butt welding pipe fitting.
Background technique
In the prior art, the two-sided line plastic-steel tube of butt joint type is by at one section Stainless Steel Tube of carbon steel tube end welding, then a kind of novel environment friendly tubing that is composited through special process with the internal and external layer plastic tube.Because Stainless Steel Tube has excellent Corrosion Protection and does not need the plastic lining protection, the inside and outside layer of a part on the stainless steel pipeline section of tubing end plastics can be divested when pipeline connects, the connection of tubing or pipe fitting is carried out in the stainless steel pipeline section butt welding that will divest inside and outside layer plastics then.
In the two-sided line plastic-steel tube water supply piping system of butt joint type, invar system butt welding plastic-coated or the inside and outside corrosion-inhibiting coating that soaks plastic pipe are the macromolecular materials of non-refractory, can wreck under the high temperature of welding and lose the antiseptic property of pipe fitting; In order to guarantee the corrosion protection and the sanitation performance of steel butt welding pipe fitting, in the two-sided line plastic-steel tube water supply piping system of butt joint type, generally adopt stainless steel butt welding pipe fitting and its supporting connection at present.Because stainless steel butt welding pipe fitting price is expensive, and capability and performance is superfluous relatively in water supply system, has caused the great wasting of resources, and increases burden for users.
The model utility content
The purpose of this utility model is to provide a kind of enamel steel butt welding pipe fitting, solves problems of the prior art, under the prerequisite that guarantees Corrosion Protection, realizes utilization of resources, reduces production cost of products.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Enamel steel butt welding pipe fitting in a kind of comprises the pipe fitting body, and described pipe fitting body port is provided with Stainless Steel Tube, is provided with enamel layer on described pipe fitting body and stainless steel pipe inner surface.
Described pipe fitting body and Stainless Steel Tube connect as one structure by butt welding.
The outer surface of described pipe fitting body and Stainless Steel Tube also is provided with anticorrosive coat.
Described enamel layer is made by glaze slip.
Described anticorrosive coat is the PE anticorrosive coat.
Described anticorrosive coat is a crosslinking with radiation PE shrink belt.
Also be provided with on the described Stainless Steel Tube with Stainless Steel Tube with treat the crosslinking with radiation PE heat-contraction sleeve that butt welding tubing end Stainless Steel Tube covers fully.
The beneficial effects of the utility model: since adopt respectively on the inside and outside surface of carbon steel pipe fitting in the enamel technology and outside coating PE contraction bands carry out anti-corrosion treatment, pipe fitting port Stainless Steel Tube has excellent decay resistance and sanitation performance, and can be directly with treat that butt welding tubing carries out butt welding and is connected, therefore, the utility model is not only simple in structure, enforcement is convenient, and its performance is suitable with stainless steel butt welding pipe fitting, and cost performance is then excellent than stainless steel butt welding pipe fitting.
The utility model is mainly used in the water supply piping system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model-embodiment's a structural representation.
Embodiment
As shown in Figure 1, on the port of pipe fitting body 1, be welded with one section Stainless Steel Tube 2, thereby be shaped to steel butt welding pipe fitting, steel butt welding pipe fitting internal surface top-pour last layer glaze slip after moulding, drying, sintering form enamel layer 3, and coat formation anticorrosive coat 4 with crosslinking with radiation PE shrink belt on the steel butt welding outer surface of pipe fittings behind the interior enamel.Before glazing and the coating shrink belt, enamel position and outer surface in the pipe fitting are coated the shrink belt position carry out the sand blast oxide layer.
Implementation process of the present utility model: as shown in Figure 2, crosslinking with radiation PE heat-contraction sleeve 5 is contained in advance treats on the butt joint type tubing 6, again 2 groups of the Stainless Steel Tubes of tubing end Stainless Steel Tube 7 and interior enamel steel butt welding pipe fitting port are connected carrying out butt welding, then crosslinking with radiation PE heat-contraction sleeve 5 is covered the Stainless Steel Tube 2 butt welding connection parts of tubing end Stainless Steel Tube 7 and pipe fitting body port, heating crosslinking with radiation PE heat-contraction sleeve 5, make it shrink this welding part of bonding covering, and with anticorrosive coat 4 overlap joint of tubing outer layer plastic anticorrosive coat 8 and this external surface of pipe fitting.
