Abstract
The utility model discloses an enhancing type spiral continuous welding coating composite steel tube for an underground coal mine. The enhancing type spiral continuous welding coating composite steel tube comprises a flange disc (1) and a tube body (2), wherein the tube body (2) is formed by one edges of steel belts and the corresponding edges of the steel belts being connected in a spiral, mechanical, meshing and encircling mode, and a spiral reinforcing rib (3) is formed at the mechanical meshing position, and the end portion of the tube body (2) is fixedly connected with the flange disc (1). The enhancing type spiral continuous welding coating composite steel tube is characterized in that the connecting position between the spiral reinforcing rib (3) and the outer wall of the tube body (2) is provided with a spiral continuous welding joint (4). The flange disc (1) is fixedly connected with a circumferential welding joint B (6) through a circumferential welding joint A (5) at the connecting position of the outer wall of the tube body (2) and the inner wall of the tube body (2). The enhancing type spiral continuous welding coating composite steel tube for the underground coal mine has the advantages of being high in strength, good in sealing performance, and capable of preventing corrosion, flame and static.
Description
Technical field
The utility model belongs to mining gas discharging Manifold technology field, relates in particular to a kind of underground mine use enhancement mode spiral continuous welding coating composite steel tube.
Background technique
Underground mine use generally has steel welded tube, seamless steel pipe, Glass Steel Tube, volute in the airduct of gas extraction.The steel welded tube requires high to the welding quality of steel pipe, in wet environment, and the corrosion that gets rusty easily, lack working life, and the tube wall of steel welded tube is thicker, and production, carrying, difficulty of construction are big, the cost height.Glass tube intensity is big, but in carrying, work progress fracture or crack takes place easily, and Glass Steel Tube easily produces static in addition, and downhole safety is threatened.Volute has higher intensity and corrosion resistance, and it is in light weight, and carrying, construction is more convenient, difficulty is low, and can not produce static, can the safety of down-hole not threatened.In the prior art, China model utility ZL200420010588.0 discloses a kind of fire damp extraction volute, comprise body, flange plate, its body is formed on one side to enclose to connect with its corresponding sides spiral interlock by Galvanized Steel Strip, and this structure is airtight, be difficult for burn into does not have static.But this structure is bited into body by steel band corresponding sides spiral, and its intensity and sealing are good inadequately.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of intensity height, good airproof performance, the uncorruptible underground mine use enhancement mode spiral continuous welding coating composite steel tube that provide.
The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions:
Underground mine use enhancement mode spiral continuous welding coating composite steel tube of the present utility model comprises body, flange plate, this body by steel band with on one side and its corresponding sides screw machine interlock enclose connect form, its interlock place forms spiral reinforcing rod; Fixedly connected with flange plate in the body end, wherein: described spiral reinforcing rod and tube wall joint are provided with spiral continuous weld.
Above-mentioned underground mine use enhancement mode spiral continuous welding coating composite steel tube, wherein: described flange plate is fixedlyed connected by welding with circumferential weld B with the circumferential weld A of tube wall and inwall joint.
Above-mentioned underground mine use enhancement mode spiral continuous welding coating composite steel tube, wherein: scribble polyethylene layer or epoxy resin layer on the inside and outside surface of described body and flange plate.
The utility model compared with prior art, has tangible beneficial effect, as can be known from the above technical solutions: this body by steel band with on one side and its corresponding sides screw machine interlock enclose connect form, its interlock place forms spiral reinforcing rod, spiral reinforcing rod and tube wall joint are provided with spiral continuous weld, spiral reinforcing rod and spiral continuous weld have improved thickness and the intensity of tube wall, and spiral continuous weld has further been strengthened intensity and the sealability of body.Flange plate is fixedlyed connected the join strength height by welding with circumferential weld B with the circumferential weld A of tube wall and inwall joint.Scribble polyethylene layer or epoxy resin layer on the inside and outside surface of body and flange plate, can play anticorrosion, fire-retardant, anlistatig function.In a word, the utility model intensity height, good seal performance and anticorrosion, fire-retardant, antistatic.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
