Steel strip reinforced PVC pipe

Abstract

The invention relates to the technical field of PVC pipes, in particular to a steel strip reinforced PVC pipe. An inner layer PVC pipe body, an outer layer PVC pipe body and a steel strip ring arranged between the inner layer PVC pipe body and the outer layer PVC pipe body are included; a first screw sleeve is installed on the top of the outer surface wall of the inner layer PVC pipe body; the position, located below the first screw sleeve, of the outer surface wall of the inner layer PVC pipe body is sleeved with the steel strip ring; the bottom of the outer surface wall of the inner layer PVC pipe body is provided with a second external thread; and the outer layer PVC pipe body is arranged on the outer side of the inner layer PVC pipe body. According to the steel strip reinforced PVC pipe, a combined rotary connection type structure is adopted, the structure facilitates assembling and fixing treatment of the steel strip reinforced PVC pipe, the workload for assembling the steel stripreinforced PVC pipe is lowered, meanwhile the stability of the overall structure of the steel strip reinforced PVC pipe is improved; and besides, a liquid filtering structure is arranged inside, a solution entering the PVC pipe is subjected to filtering treatment, the abrasion of the interior of the pipeline is lowered, and meanwhile the liquid circulating stability is improved.

Description

technical field [0001] The invention relates to the technical field of PVC pipes, in particular to a steel belt reinforced PVC pipe. Background technique [0002] The main component of PVC pipe is polyvinyl chloride, adding appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., extruded by plastic extruder and injection molded by injection molding machine, through cooling, curing, shaping, inspection, packaging, etc. Process to complete the production of pipes and fittings. The top layer of PVC pipe is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a synthetic material that is loved, popular and widely used in the world today. [0003] PVC pipe technology and design principles: [0004] 1. The resin should be PVC-SC5 resin or PVC-SG4 resin, that is, polyvinyl chloride resin with a polymerization degree of 1200-1000. [0005] 2. Add heat stabilization system. Choose according to the ac...
