Prefabricated polyurethane insulation pipe
Nowadays, the judgment of whether polyurethane insulation materials are qualified has become an urgent task for some units and enterprises in the insulation industry. Because nowadays, counterfeit polyurethane insulation products are flying everywhere. Here is a warning to everyone to try to choose legitimate manufacturers when purchasing polyurethane insulation materials, such as Cangzhou North Steel Pipe Industry. In addition, in determining whether it is qualified, it is also possible to check whether the polyurethane insulation pipeline manufacturer meets the standards, whether there is a fire prevention certificate, and whether there is after-sales service guarantee. Today, let's talk about the evaluation criteria for polyurethane insulation material products.

Nowadays, the judgment of whether polyurethane insulation materials are qualified has become an urgent task for some units and enterprises in the insulation industry. Because nowadays, counterfeit polyurethane insulation products are flying everywhere.
Here is a warning to everyone to try to choose legitimate manufacturers when purchasing polyurethane insulation materials, such as Cangzhou North Steel Pipe Industry. In addition, in determining whether it is qualified, it is also possible to check whether the polyurethane insulation pipeline manufacturer meets the standards, whether there is a fire prevention certificate, and whether there is after-sales service guarantee. Today, let's talk about the evaluation criteria for polyurethane insulation material products.
1. It is not enough to only consider the oxidation index, but also whether the insulation material meets the standard. Generally speaking, the oxidation index of the surface of polyurethane insulated pipeline engineering should be checked before starting construction, and it should also be checked again after completion. Because if one of the processes is missing, it is possible to mix unqualified polyurethane insulation pipes into the market. The oxidation index refers to the flame retardancy of insulation materials, with a standard flame retardant oxidation index OI ≥ 30%. Some companies only spot check the blind spots of the oxidation index, and as long as one index passes the inspection level, a series of problems are hidden. This reverse order approach will reduce the energy consumption of the insulation layer of polyurethane insulated pipelines.
2. Checking the capacity of polyurethane insulation materials is also one of the methods to verify whether the materials are qualified. The capacity determines the thermal conductivity, strength, and dimensional stability. The capacity unit of qualified insulation materials is generally between 48-60 kilograms per cubic meter. But some companies, in order to boost the index, add a large amount of inorganic materials, which will increase the capacity of insulation materials per cubic meter. Damaged the physical structure and insulation properties of insulation materials. In this way, the insulation layer of polyurethane insulated pipes will suddenly increase water absorption, shell peeling, and detachment. If the capacity is too low, it will cause deformation and mold.
3. Polyurethane insulation materials and main machinery should meet the design requirements. The material of the pipeline should be made of polyurethane foaming agent or additive. Inspect the polyurethane insulation pipeline before starting work, and proceed to the next work only after passing the standards. After sealing, the protective measures for the polyurethane insulation layer of the pipeline are also improved. Prevent liquids or suspended substances from entering the insulation layer, thereby affecting the sealing. After inspection, there are no suspended solids or other impurities, and the seal is good.
Purchasing products requires high value, otherwise it will waste a lot of money. Polyurethane insulation pipeline products can cause many quality problems throughout the entire usage process. Nowadays, polyurethane insulation pipes are needed in many industries. If the value of use is not high, the insulation pipe will rupture, leading to some inevitable accidents.
