Polyurethane foam insulated steel pipe

Description :

Insulated steel pipe is a composite insulated pipeline composed of working steel pipe, insulation layer, and protective layer. Through professional processes, the insulation material is tightly combined with the steel pipe, combining the high strength and pressure resistance of the steel pipe with excellent insulation performance. It can effectively reduce the heat loss of the conveying medium and achieve long-distance stable transportation of low-temperature and high-temperature media. It is the core pipe material in the fields of centralized heating, central air conditioning, thermal network, and chemical insulation.

Core advantages of the product

1.  Excellent thermal insulation performance

Using high-density insulation materials as the intermediate layer has low thermal conductivity and excellent insulation effect, which can significantly reduce the heat loss of transportation media such as hot water, steam, and hot oil. The energy-saving effect is significant, and long-term use can effectively reduce operating costs.

2.  Durable under pressure and structurally stable

The inner working steel pipe is made of high-quality seamless steel pipe and spiral steel pipe, with high mechanical strength, compressive and impact resistance, good sealing performance, and can withstand pipeline transportation pressure. It is suitable for various installation environments such as underground deep burial and overhead laying, and has a long overall service life.

3.  Anti corrosion and waterproof, with strong protective properties

The outer layer is equipped with high-density polyethylene sheath, glass fiber reinforced plastic or anti-corrosion coating to isolate the erosion of groundwater, soil and rainwater, and has super anti-corrosion, waterproof and anti-aging properties to avoid the failure of the insulation layer due to moisture and ensure the long-term stable operation of the pipeline.

4.  Convenient construction and high cost-effectiveness

The pipeline is prefabricated as a whole and directly connected and installed on site, without the need for secondary insulation treatment, greatly reducing the construction period; The insulation layer of the pipeline is tightly adhered to the steel pipe, without detachment or deformation, and the maintenance cost in the later stage is extremely low. The comprehensive cost-effectiveness far exceeds that of ordinary pipelines.

5.  Wide applicable temperature range

It can be adapted to transport high-temperature steam, hot water, hot oil, and low-temperature fluids, with stable resistance to high and low temperatures. The insulation layer is non combustible and resistant to high temperatures, meeting the transportation needs of different media and working conditions.

6.  Environmentally friendly, energy-saving, safe and reliable

Insulation materials are environmentally friendly, non-toxic, odorless, and will not contaminate the conveying medium; The pipeline has strong sealing, no medium leakage, eliminates heat waste, and meets the requirements of energy-saving and environmental protection engineering.

Mainstream product classification

1.  Polyurethane insulated steel pipe

With polyurethane foam as the thermal insulation layer and high-density polyethylene as the external protective pipe, it has good thermal insulation effect, light weight and convenient construction, and is suitable for municipal central heating, residential heating and central air-conditioning circulating water pipelines.

2.  Steel sleeve steel steam insulated steel pipe

Internal steel pipe+insulation layer+external protective steel pipe structure, resistant to high temperature and high pressure, specially designed for high-temperature steam transportation, suitable for power plants, thermal companies, and industrial steam pipeline engineering.

3.  Fiberglass protective insulation steel pipe

The outer layer is protected by fiberglass, which is resistant to corrosion, acid and alkali, and suitable for transporting thermal and chemical fluids in harsh environments such as humid and saline alkali land.

4.  Rock wool insulated steel pipe

Excellent high temperature resistance, moderate cost, suitable for insulation of industrial high-temperature media, thermal pipelines, and power plant circulating water pipelines.
