Introduced double-wall corrugated pipe butt-type
On the automatic rolling screen
Release time：2013/1/23 11:59:20 【Typeface：Big Middle Small】

One kind of butt-type double-wall corrugated pipe, is a tubular construction materials manufacturing technology, mainly by a certain number of uniformly distributed interval of laminated wall (3) and the outer layer (1) and inner (2) consisting of hollow Double wall, double wall placed between the hollow laminated wall thickening (4) and other accessories. The thickening of the wall thickness e as a laminated wall thickness of 1.5-5 times the laminate, the length L for the 20-50mm. This practical new design is reasonable, in a number of laminated hollow double-wall thickening of the wall between the settings, compression molding in continuous production from the existing restrictions on fixed-length bellows to improve efficiency, reduce production costs ; in the transport, in order to facilitate the move, along the central part of the wall thickening of laminated cut off; in the installation, use Butt welding to both ends of the laminated wall thickening can be melted butt, no seals, A fundamental solution to the existing corrugated pipes ring connected easily occur due to corrosion leakage, broadening the use of bellows.
