Description
Technical field
The present invention relates to a kind of molded steel-plastics composite pipe of screw-button, belong to ventilation, supplying drainage design field.
Background technology
The air circulation that spiral duct is mainly used between UNICOM two places, plays ventilated effect.Spiral duct mainly has at present: zinc-coated spiral airduct, rustless steel spiral duct, and it is mainly used in cleaning system and sends airduct, central air-conditioning ventilation duct, industry supply and exhaust ventilation duct, environment friendly system suction airduct, mining drainage gas pipe etc. back to.It is big, yielding that the existing spiral duct being made up of cold-rolled steel coils overcomes original inorganic glass-fiber reinforced plastic poor toughness, fragility, the shortcoming such as damp suction surface halide accumulation, poor water resistance, and the shortcoming such as seamless steel pipe weight is big, installation difficulty is high, poor water resistance, corrosion-resistant, wall unevenness are even.
Existing spiral duct be by cold-rolled steel coils, rustless steel with it while enclosing to connect with another corresponding sides screw occlusion and forming.But being susceptible to chemical reaction due to iron sheet in some environments, cause burn into get rusty, and zinc changes in dry air hardly, as in malaria, zinc surface can generate the basic zinc carbonate film of densification.Therefore zinc-coated spiral airduct is mainly plating last layer zinc on airduct iron sheet, and iron sheet plays the effect of protection.But above-mentioned zinc-plated operation is complex loaded down with trivial details, as there is the iron sheet careless mistake in zinc-plated operation, then easily causes the quality problems of ventilation duct.
Owing to spiral duct is applied at special dimensions such as industry, down-hole gas sucking releasings, its air-tightness is required the highest, such as relating to the field of Embedment and installation, then the ring stiffness of tubing is required the strictest, the most easily occur in the problem causing tube wall deformation, rupturing and come off under the pressure of outside.
Secondly, for drain pipe field, currently mainly based on steel band reinforced polyethylene spiral ripple pipe, but, as DN >=1000mm, the ring stiffness of tubing reduces the biggest, and to ensure that it has higher ring stiffness and is necessary for reaching to design requirement by increasing the base material such as polythene material, thickness of strips, the cost of tubing strengthens the most therewith simultaneously, and along with the increase of thickness of strips specification, steel band turns to moulding process to be consequently increased difficulty；
Further, because steel band reinforced polyethylene spiral ripple pipe is applied in drainage system, be primarily subjected to is the pressure that brings of outside, therefore, for manufacturer, in tubing designs, the ring stiffness to tubing requires more strict, and often have ignored the design bearing pressure inside tubing, cannot the breakthrough of acquisition of technology in terms of pressure pipeline, therefore also limit the application of steel band reinforced polyethylene spiral ripple pipe.
