Embodiment Construction

[0034] 1. Prepare the water supply pipeline

[0035] According to the specific fluid medium to be transported, select the appropriate water supply pipeline, and factors such as pressure, flow rate, heat resistance, and corrosion resistance should be considered when selecting. Commonly used water supply pipes are: plastic water supply pipes, such as chlorinated polyvinyl chloride (CPVC) water supply pipes, polyvinyl chloride (UPVC) water supply pipes, random copolymerized polypropylene (PPR) water supply pipes, polyethylene (PE) water supply pipes, etc. ; and metal water supply pipes, such as copper water supply pipes, stainless steel water supply pipes, galvanized water supply pipes or steel-plastic composite water supply pipes, etc.

[0036] 2. Preparation of rubber-plastic foam insulation pipe

[0037] According to the temperature of the fluid medium to be transported, the ambient temperature, the fire protection coefficient and other factors, the thickness of the rubber-pl...

Abstract

The invention discloses a preparation method of a rubber and plastic heat preservation pipeline system. The assembly of the rubber and plastic heat preservation pipeline system is finished under the action of pressure through adopting a negative pressure guiding pipe assembly and an air pressure balance guiding head. The preparation method provided by the invention has the advantages that the installation is simple, convenient and rapid, the degree of mechanization is high and the like; the rubber and plastic heat preservation pipeline has good heat retaining property, weather ability and stability, and the service life of the rubber and plastic heat preservation pipeline is prolonged.

Description

technical field [0001] The invention relates to a method and device for preparing a thermal insulation pipeline system, in particular to a method and device for preparing a rubber-plastic thermal insulation pipeline system. Background technique [0002] The rubber-plastic thermal insulation piping system is an insulated water supply piping system consisting of a water supply pipe located in the inner layer, a rubber-plastic foam insulation pipe located in the middle layer, and a protective pipe located in the outer layer. The preparation method of the traditional rubber-plastic insulation pipe system is as follows: (1) Install the water supply pipe (plastic or metal material) connecting the inner layer; (2) Take the rubber-plastic foam insulation pipe, cut it along the side, and then put the rubber-plastic foam The insulation pipe is wrapped on the outside of the water supply pipe, and the cut is bonded with glue, so that the rubber-plastic foam insulation pipe is tightly at...
