PE insulation pipe also called PE outer protective tube, jacket tube, sleeve tube .Direct burying PE insulation pipe is made up of high density polyethylene outer protective layer, polyurethane rigid foam plastic insulation material and steel pipe.The insulation material is rigid polyurethane foam ,the density is 60kg/m3~80kg/m3 , fully fill the gap between steel pipe and casing pipe,and have a certain degree of adhesive strength. Form a firm whole between the steel pipe, the outer tube and the insulation layer. Foam of Polyurethane directly buried insulating pipe has good mechanical and thermal insulation properties . Under normal situation, it can withstand high temperatures of 120°C and can withstand high temperatures up to 180°C through modification or combination with other insulation materials.Applicable to a variety of cold, hot water, high and low temperature pipeline’s insulation engineering.
2 meters PE thermal insulation pipe production line which manufactured in SHANGHAI JWELL PIPE EQUIPMENT CO.,LTD , have a leading position in the industry, and the design is unique and novel . Adopt high efficiency single screw extruder , high degree of automation, easy operation, continuous production, stable and reliable.Due to the equipment production is stable ,mature technology ,customers are very satisfied .
Piping PUF insulation and fittings is a rigid structure "pipe in pipe" consisting of steel or galvanized steel carrier pipe, a layer of polyurethane foam insulation and the outer jacket pipe protective of high-density polyethylene - for underground installation or sheet galvanized steel - for above-ground pad.
Rigidity due to the presence of strong ties between the steel pipe layer polyurethane insulation and jacket pipe and provides pre-shot blast or blast cleaning the surface of the steel pipe, optimum performance polyurethane insulation, corona surface of polyethylene pipe shell.
The main performance indicators and technical innovations of the PE960-1880 insulation pipe production line are as follows:
1. Basic performance indicators: pipe diameter range 960-1880mm, pipe wall thickness 14-17mm, production speed 0.1-0.45m/min, total installed capacity of 550kw.
2. The application of solid-liquid phase separation screw technology, the service life and output of the ordinary screw is 3 times, can achieve high-speed and efficient extrusion melting, and can ensure the quality of plasticization.
3. The spiral shunt head of the gas water supply pipeline is successfully applied to the production of large thin-wall pipes. The production pipe has high internal pressure strength, no trace of confluence, the pipe is stable and reliable, and it is not easy to break, and the scaffold shunt head is eliminated.
