Shandong PE pipe which brand manufacturers 182-539-19338

(A), using Butt welder to heat the pipe end (butt fusion temperature of 210 ℃ ± 10 ℃) with tube end after thawing, quickly bonded during its installation Butt Butt, maintain a certain pressure by cooling to achieve the purpose of welding. Use diameter range: dn≥90mm steps: the need to connect at the same time on two PE pipe fuser fixture (jig according to the diameter size of the folder to be installed to replace the block) Each other end of the pipe with a pipe stand hold up to the same level. The pipe ends are cut smooth with an electric rotary knife, ensure that the two contact surfaces of pipe fully fit. The electrolysis hot plate heated to 210 ℃, placed at both ends of the pipe end face intermediate, operating electro-hydraulic device so that the two pipe ends simultaneously in full contact with the electric heating plate. Deprived of the heating plate is again operated hydraulic device, so that the two end faces of the pipe has been fully melted butt and lock hydraulic device (to prevent rebound) to maintain a certain cooling time release, the operation is completed. Construction is completed, subject to acceptance test pressure is applied only after buried put into use. (B), melt socket installation suitable diameter dn≤110mm steps: Use cutter or scissors to cut PE pipe according to the installation needs. In the pipe insertion depth markers. The fuser warming within 210 ℃. Meanwhile melt PE pipe, tube and socket (socket in place to be after a moment let go, prohibit twist in heating, socket, cooling process) natural cooling. After construction is subject to acceptance after pressure test before sealing tube put into use. (C), fused connection diameter dn≤630mm steps: The PE pipe is fully inserted into the fused pipe. The two wires are dedicated fused machine switched fused pipe is negative. Power heated electric heating wire is melted PE internal contact points. Cooling is completed. After construction is subject to acceptance after pressure test before sealing tube put into use.
