Connection method of steel band reinforced spiral ripple pipe

Abstract

The present invention provides a connecting method of steel strip enhanced spiral bellows, said two steel strip enhanced polyethylene spiral bellows are in-spigot-and-socket connected through a plug nested with sealed ring. The invention uses the in-spigot-and-socket connection never used on the connecting technology of steel strip enhanced polyethylene spiral bellows, the accessory of in-spigot-and-socket connection includes one plug and sealed ring, the pipe connection is reliable through the spigot-and-socket-connection of sealed ring on the plug, the sealing performance of pipeline system is superior, operation is simple, installation and construction is easy, the construction comprehensive cost is lower and the construction efficiency is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of steel strip reinforced spiral corrugated pipes, in particular to a connection method of steel strip reinforced spiral corrugated pipes. technical background [0002] Steel belt reinforced polyethylene spiral corrugated pipe is a composite pipe formed by winding. It integrates the advantages of high rigidity of steel belt and polyethylene's corrosion resistance, low friction resistance, and wear resistance. It has high ring stiffness, and The overall molding process is good, the seam tensile strength and anti-corrosion are high, and the service life is longer; it has a variety of reliable and convenient connection methods. [0003] At present, the connection methods of steel strip reinforced polyethylene spiral corrugated pipe mainly include: hot melt extrusion welding, electric hot melt belt welding and heat shrinkable tube (belt) connection. [0004] Hot-melt extrusion welding is a...

Problems solved by technology

[0008] 1. It is troublesome to place the pipes. In the harsh environment of the construction site, it is extremely difficult to align the pipes well, and the gap is less than 10mm;

[0009] 2. It is extremely unrealistic to use extrusion welding torch to weld at the wrong position. An extrusion welding torch is worth tens of thousands of yuan. The construction unit will not be willing to invest in it. Generally, it will be provided by the pipeline manufacturer. Dozens to hundreds of construction sites, if each site is equipped with an extrusion welding torch, the investment can be imagined

[0010] 3. The wrong position is manually welded. If only the wrong position is welded, there will be 100% leakage, so the pipe has to be welded for a week. If this is the case, it will be troublesome.
