A composite pipe of stainless steel and plastic that can be used for hot-melt connection is composed of an outer layer (1) of a welded stainless steel pipe, a middle layer (2) of a plastic pipe and an inner layer (3) of a welded stainless steel pipe. The outer layer of the welded stainless steel pipe (1) is connected to the inner layer of the welded stainless steel pipe (3) through the middle layer of the plastic pipe (2), and the connection between the stainless steel and the plastic composite pipe is to peel off a section of the welded stainless steel pipe from the end of the stainless steel and plastic composite pipe. Layers are inserted into the joint cavity of the plastic pipe fitting (4) for hot-melt connection to form a stainless steel and plastic composite pipe as a whole. It has beautiful appearance, anti-ultraviolet, strong anti-aging ability, high surface hardness, increased rigidity, heat resistance and pressure resistance.
Description
One, technical field
The utility model relates to a kind of stainless steel and plastic composite pipe that hot melt connects that can be used for, and belongs to plastics and metal composite shaping operation field.
Two, background technique
Polymer is as the increasingly extensive fields such as building supply, oil transportation gas transmission that are applied to of pipeline material at present.For example PVC, polyethylene, polypropylene, chlorinated polynvinyl chloride (CPVC), crosslinked polyethylene pipe etc.The pipeline of these kinds has easy construction, connects simple advantage, and transporting water does not produce corrosion.But, compare with metallic conduit, pure plastic pipe withstand voltage, resistance to heat is relatively poor, if working more than 70 ℃, its working pressure just needs to descend significantly, could keep the working life than length, some in addition can not bear such serviceability temperature fully.More outstanding is that uvioresistant, ageing resistance are poor.Along with science and technology development, people are more and more higher to the requirement of life and industrial process waters pipe, and aluminium-plastic composite pipe is used widely in the building supply field.The working pressure that this class is born fluid with metal tube as framework material, at the metal inner and outer surface in conjunction with two layers of plastic as protective layer, this structure has been given full play to the advantage of metallic material and plastic materials, and the heat-resisting withstand voltage properties of pipeline all is improved.Chinese patent 0221531.X and 02222702.4 existing report, it connects aluminium-plastic composite pipe and exists comparatively serious leakage and done some improvement, however hidden danger such as aluminium-plastic composite pipe still has aluminium and plastics are compound not closely, plastics and metal easily come off.
Three, summary of the invention
The purpose of this utility model is that a kind of stainless steel and plastic composite pipe that hot melt connects that can be used for is provided at the deficiencies in the prior art, and it has, and beautiful shape, uvioresistant, ageing resistance are strong, rigidity and resistance to pressure are strong, be convenient to high rise building water supply and oil, the use of gas conveying etc.
The purpose of this utility model is realized by following technical measures.
The stainless steel and the plastic composite pipe that can be used for the hot melt connection are made up of soldering stainless steel outer tube layer, plastic tube middle level and soldering stainless steel inner tube layer, the soldering stainless steel outer tube layer is connected with the soldering stainless steel inner tube layer by the plastic tube middle level, and being connected between stainless steel and the plastic composite pipe is to peel off by stainless steel and plastic composite pipe termination that hot melt connects and composes stainless steel and plastic composite pipe integral body in the joint cavity that one section soldering stainless steel outer tube layer inserts plastic pipe.
The plastic tube middle level is any in the foam material of polyethylene, polypropylene, PVC or this different materials.The thickness of plastic pipe layer is outer field 0.5～10.0 times of welded stainless steel pipe.
The welded stainless steel pipe inner layer outer surface is provided with recessed road or roller flower.
The utlity model has following advantage:
1, the utility model beautiful shape, uvioresistant, ageing resistance is strong, surface hardness is high, increase its rigidity, heat-resisting, resistance to pressure.
2, with short production cycle, cost is low, in light weight, fitting operation convenient.
3, quality is good, and the reliability height is used for and plastic pipe sweat soldering ne-leakage, good sealing effect.
Four, description of drawings
Stainless steel and plastic composite pipe structural representation that Fig. 1 connects for hot melt.
1 soldering stainless steel outer tube layer, 2 plastic tube middle levels, 3 soldering stainless steel inner tube layers, 4 plastic pipes.
Fig. 2 is a welded stainless steel pipe inner layer outer surface roller flower schematic representation.
Five, embodiment
Below by embodiment the utility model is specifically described, but can not be with present embodiment as the restriction to the utility model protection domain.
Embodiment
The stainless steel and the plastic composite pipe that can be used for the hot melt connection are made up of soldering stainless steel outer tube layer 1, plastic tube middle level 2 and soldering stainless steel inner tube layer 3, soldering stainless steel outer tube layer 1 is connected with soldering stainless steel inner tube layer 3 by plastic tube middle level 2, and being connected between stainless steel and the plastic composite pipe is to peel off by stainless steel and plastic composite pipe termination that hot melt connects and composes stainless steel and plastic composite pipe integral body in the joint cavity that one section soldering stainless steel outer tube layer inserts plastic pipe 4.The plastic tube middle level is any in the foam material of polyethylene, polypropylene, PVC or this different materials.The thickness of plastic pipe layer is outer field 0.5～10.0 times of welded stainless steel pipe.The outer surface of soldering stainless steel inner tube layer 3 is provided with recessed road or roller flower, increases compound surface of contact and Adhesion force, to improve stainless steel and plastics composite effect.
