The cold insulation tube holder can withstand various loads brought by the pipe system, and at the same time, it is a part of the cold insulation of the pipeline.
The cooling tube support system mainly includes the following parts:
1. Sliding cooling tube holder
2. Guided cooling tube support (including vertical pipe guide tube support)
3. Limit/fixed cooling tube holder
4. Pad system
Product performance and technical indicators
(1) Cold insulation material
The cold insulation material is the most important part of the cold insulation tube holder. The cold insulation material of the Zhenshen cold insulation tube holder uses high-density polyisocyanurate (HDPIR). High-density polyisocyanurate is made of isocyanate and polyether as the main raw materials, plus foaming agent, catalyst and fire retardant, and is produced by high-speed stirring and mixing reaction with characteristics of plastic, rubber and cork. aggregates. The vesicle is composed of thousands of tiny and uniform independent cells in a three-dimensional honeycomb structure. Its high density, low thermal conductivity, low water absorption, and texture are better than wood.

(2) Other auxiliary materials
In addition to the main cold insulation materials, the cold insulation pipe support can also be equipped with the following auxiliary materials according to requirements: moisture-proof layer, metal protective layer, rubber sheet, metal pipe clamp, bolt and nut, butterfly spring, cold insulation washer, PTFE sliding To meet the design needs and ensure the safe and reliable use of the tube support.
Applications
Mainly used in petrochemical plants, liquefied gas plants, freezers and central air-conditioning system pipelines, equipment load-bearing and heat insulation.
Packaging and storage
The pipe support blocks are factory assembled, wrapped in black polyethylene bags and packed in wooden cases.
Use and precautions
(1) The pipe bracket and the cushion block are assembled in a complete set, and then assembled on site after disassembly.
(2) Installation Install according to the requirements of the manual.
