Trailer element in isolation PPU
Shaped product the trailer element of the pipeline with a conclusion cable in the isolation PPU made in accordance with GOST 30732-2006 "Pipes and shaped products steel with thermal isolation from polyurethane foam with a protective cover" is intended for connection of the copper conductors laid in a heat-insulation layer of polyurethane foam on all extent of a certain site of the preisolated pipeline to trailer terminals of system of quick and remote control. In the course of installation of this product on the pipeline the monitoring system of a condition of thermal isolation of PPU of the pipeline consisting directly of pipe PPU, the isolated shaped elements including elements with a cable of a conclusion and devices of the UEC system with auxiliary designs becomes isolated (terminals, detectors, 3rd vein cables of a conclusion, thermal chambers, land and wall a cover).
Structurally trailer element of the pipeline with a cable of a conclusion represents a piece of the preisolated pipe PPU, the metal cap of isolation attached to it, and also special connection among themselves of copper conductors and the copper cable closed on the steel pipeline and leaving through a special opening in the protective external cover of a product which is in the middle of an element of the pipeline. Length of a shaped product makes usually 2200 mm at standard option of production and 1500 mm in the shortened option.
The trailer element of the pipeline with a conclusion cable in isolation PPU in thermal chambers in initial and final places of the pipeline site determined by extent in isolation PPU is established. The place of input of an element in a chamber has to be pressurized by the special cuffs of wall input protecting the polyethylene or steel PPU insulating covering of the pipeline. The quantity of these products and the place of their arrangement are defined by the project on construction of the thermal route.
The manufacturing techniques of a trailer element in polyethylene or steel protective covers have the features and have to conform to requirements imposed to products of this category as reliable functioning of the UEC system of a heating main at failure of this element of the pipeline is extremely complicated. According to requirements of the set of rules of the joint venture 41-105-2002 in control points connecting cables have to join alarm conductors through tight cable conclusions and the design of cable conclusions has to provide tightness during all service life.
The ALMAZIT company makes trailer elements of the pipeline with a conclusion cable for all types of laying of pipelines in isolation PPU diameters to 820 mm.
