Steel-plastic composite pipe connection methods
Steel-plastic composite pipes are typically connected to pipes through three methods: flange connection, grooved connection, and threaded connection. To address potential leaks in the threaded connection process, a secondary sealing technology has been developed. In addition to wrapping the threaded area with a sealing tape for the initial seal, a silicone rubber gasket is also placed inside the injection-molded pipe fittings. This ensures that the end face of the steel-plastic composite pipe is sealed at the root with the fitting, thereby isolating metal from water and preventing any contact between the metal components and water. This solves the corrosion problem in the connection between steel-plastic composite pipes and pipe fittings, ensuring the quality of water supply.
Steel-plastic composite pipes are an economical cross-section steel product, widely used in crude oil extraction and processing, pipeline transportation, mechanical manufacturing, and large-scale venue construction. There is a wide variety of steel pipe types, with varying product performance, primarily produced through three main methods: hot rolling, welding, and cold working. Steel-plastic composite pipes are manufactured by piercing solid billets or ingots and rolling them into hollow cross-section steel pipes. High-alloy, difficult-to-deform steel grades are produced using extrusion methods, and the steel-plastic composite pipes are mainly produced by extrusion. The process involves bending and forming steel plates or strips into the required cross-sectional shape using various shaping methods, followed by welding the seams together using different welding techniques to obtain the steel pipe.
