1、 The inner wall of the pipe is smooth, with low fluid resistance and no rusting. The water quality requirements are not strict and there is no accumulation of mud. 2、 Good low temperature resistance, PE polyethylene pipes have a wide temperature range and can be used normally in environments ranging from -20 ℃ to 40 ℃.

Welding slag, rust, slag, etc. in the pipeline can cause blockage or jamming in the throttle port, guide part, and balance hole of the lower valve cover, resulting in scratches and abrasions on the valve core surface and guide surface,

Pipe Clamp or pipe support Material Carbon steel and stainless steel Hot dip galvanised - EN ISO 1461: 1999 On request: self colour & stainless steel There are many types of pipe clamp, mainly including the following: ‌sliding type pipe clamp: suitable for applications requiring pipe or equipment displacement stress, such as petrochemical, electric power and other industries. ‌ 3 ‌Fixed pipe bracket: used for fixed support of pipelines to ensure the stability and safety of pipelines. ‌Guided pipe support: In addition to supporting the pipe, it can also guide the displacement of the pipe in a specific direction. ‌heat insulation pipe support: such as ‌ vermiculite heat insulation pipe support, used for heat insulation and reduce energy loss. ‌ ‌Pipe clamp bracket: connects to the pipeline through the pipe clamp to support and fix the pipeline

The high-pressure flange sealing surface of the high-pressure hydrogenation unit usually adopts RJ surface, and the gasket used is a metal ring gasket,

Hexagonal bolts are currently widely used in the fastener industry. Compared to straight and cross shaped heads, their assembly is less prone to slipping teeth and has higher torque. Compared to the twelve cornered and multi toothed heads, its structure is simple and its cost is low. Therefore, the comprehensive price of hexagonal bolts is relatively high.
