Steel-plastic combined pipe fitting

Abstract

The invention provides a steel-plastic combined pipe fitting which integrates the anticorrosion performance of the plastic material and the structure stability of the steel pipe material. The steel-plastic combined pipe fitting comprises a basic stainless steel pipe fitting structure, an inner resin layer adhered on the inner surface of the basic stainless steel pipe fitting structure, and an outer resin layer adhered on the outer surface of the basic stainless steel pipe fitting structure; the inner resin layer is a polyvinyl chloride resin layer; the outer resin layer includes an epoxy resin layer and / or a gel coat resin layer. According to the steel-plastic combined pipe fitting, the basic stainless steel pipe fitting structure is used as a supporting structure, so that the stability is improved, and the firmness is increased; the inner resin layer and the outer resin layer are anticorrosive, and thus the service life of the combined pipe fitting is prolonged; the steel-plastic combined pipe fitting is simple in structure, convenient to repair, and low in processing cost.

Description

technical field [0001] The invention belongs to the field of pipe fittings, in particular to a steel-plastic composite pipe fitting. Background technique [0002] In the existing technology, most of the pipe fittings are all-plastic pipe fittings. Plastic pipes are widely used in various production fields due to their light weight, corrosion resistance, good impact resistance and tensile strength, small friction coefficient, small fluid resistance, and convenient installation. However, the structure of plastic pipes is not firm enough and easy to deform, and steel pipes can overcome the above-mentioned shortcomings of plastic pipes. However, due to the nature of the steel pipe itself, there are technical problems such as corrosion and rust. Contents of the invention [0003] The problem to be solved by the present invention is to provide a steel-plastic composite pipe fitting, which can combine the corrosion resistance of plastic material and the structural stability of st...
