Product Details

Steel sleeve steel steam insulation pipe manufacturer

Tianjin Haimen Building Materials Co., Ltd. has been specializing in the production and processing of polyurethane prefabricated buried insulation pipes, steel sleeve steel steam buried insulation pipes, and prefabricated buried pipe fittings for more than 20 years. We welcome new and old customers to consult and negotiate .....

Steam buried insulation pipes can be divided into two types of structures: internal sliding and external sliding. Internally sliding buried steam insulation pipe, the insulation material and outer protective pipe remain relatively stationary, mainly due to the thermal expansion of the working steel pipe moving within the insulation material. This structure is suitable for hard insulation materials. The advantage is that there is no need to set a support ring between the working steel pipe and the outer protective pipe, and the inner wall of the outer protective pipe is not easily corroded. However, the disadvantage is that it can easily cause eccentricity and crushing of the insulation material. External sliding steel sleeve steel insulation pipe, with the sliding surface on the inner surface of the outer protective pipe, and the insulation material moves together with the working steel pipe.

The structure of steam buried insulation pipe is suitable for soft insulation materials. Its advantages include ensuring that heat flow does not leak out, solving the problem of increased friction caused by radial expansion, and having support rings inside, which will not cause eccentricity or crushing of the insulation material. According to the design and requirements, the outer protective layer of the steel insulated pipe can be treated with three-layer PE, epoxy coal tar or fiberglass anti-corrosion technology measures to prevent steel pipe corrosion.

Prefabricated steam insulation pipes can be divided into two types of structures: internal sliding and external sliding.

Internal sliding buried steam insulation pipe

Internally sliding buried steam insulation pipe, the insulation material and outer protective pipe remain relatively stationary, mainly due to the thermal expansion of the working steel pipe moving within the insulation material. This structure is suitable for hard insulation materials. The advantage is that there is no need to set a support ring between the working steel pipe and the outer protective pipe, and the inner wall of the outer protective pipe is not easily corroded. However, the disadvantage is that it can easily cause eccentricity and crushing of the insulation material.

External sliding steel sleeve steel insulation pipe

The external sliding steel sleeve steel insulation pipe has a sliding surface on the inner surface of the outer protective pipe, and the insulation material moves together with the working steel pipe. This structure is suitable for soft insulation materials, and its advantages are to ensure that heat flow does not leak out, solve the problem of increased friction caused by radial expansion, and have support rings inside, which will not cause eccentricity or crushing of the insulation material. According to the design and requirements, the outer protective layer of the steel insulated pipe can be treated with three-layer PE, epoxy coal tar or fiberglass anti-corrosion technology measures to prevent steel pipe corrosion.

Steel sleeve steel steam insulation pipe manufacturerStructure:

The prefabricated buried insulation pipe consists of several parts, including working steel pipe, calcium silicate, reflective layer, fastening steel strip, sliding bracket, glass wool, air layer, outer protective steel pipe, and wrapped fiberglass.

(1) All inorganic materials, non combustible, and do not decompose toxic gases.

(2) Easy to process, sawing and cutting, convenient on-site construction, and low loss.

(3) The aqueous solution is neutral or weakly alkaline and will not corrode pipelines and equipment.

▲Polyurethane direct buried insulation pipe

Polyethylene outer protective pipe polyurethane prefabricated buried insulation pipe has excellent overall performance. The product strictly follows the CJ/T114-2000 (EN253:2009) standard. The working steel pipe adopts the process of shot blasting rust removal on the outer surface and corona treatment on the inner surface of the outer protective pipe to ensure the three in one performance of the insulation pipe. The service life is as long as 30-50 years, with strong stability and extremely low maintenance costs. The insulation effect is 4 to 9 times higher than other insulation pipes, and the heat loss is only 25% of traditional pipes. Under normal circumstances, it can withstand temperatures of 120 ℃, and the highest peak value can reach 150 ℃. Outer protective tube density ≥ 940kg/m ³, tensile strength ≥ 20Mpa; Thermal insulation foam density ≥ 60kg/m ³, compression strength ≥ 300Kpa, thermal conductivity ≤ 0.03w (m.k), closed cell rate ≥ 90%.

Characteristics of polyurethane buried insulation pipe:

(1) Convenient production and reduced engineering cost

(2) Excellent insulation effect, energy-saving and environmentally friendly

(3) Long service life and low maintenance costs

(4) Easy construction, reducing environmental damage

Polyurethane direct buried insulation pipe structure:

(1) Working steel pipes: According to the technical requirements of the conveying medium, seamless steel pipes, double-sided submerged arc spiral welded steel pipes are used.

(2) Thermal insulation layer: rigid polyurethane foam.

(3) Protective shell: Made of high-density polyethylene or fiberglass.

(4) Leakage alarm line: When manufacturing high-temperature prefabricated buried insulation pipes, an alarm line is buried in the insulation layer near the steel pipe. Once a leakage occurs in a certain part of the pipeline, the transmission of the alarm line can trigger an alarm on the detection instrument and display the section of the pipe that quickly handles the leakage, ensuring the safe operation of the heating network. The accurate location and degree of leakage of water, in order to notify maintenance personnel quickly

Safety of polyurethane buried insulation pipe

The high-temperature prefabricated buried insulation pipe designed and produced by Tianjin Haimen Building Materials Co., Ltd. can be equipped with a leakage alarm line according to requirements. Once a leakage occurs in a certain part of the pipeline, the accurate location and degree of leakage of the insulation pipe can be displayed on the detection instrument through the transmission of the alarm line, so as to notify the leakage personnel to quickly deal with the leaking pipe section and ensure the safe operation of the heating pipe network.

The properties of polyurethane insulation pipes

High temperature prefabricated buried insulation pipes not only have the technical and practical performance of traditional trench and overhead pipeline laying, but also have significant social and economic benefits, and are also powerful measures for heating energy conservation.

Tianjin Haimen Building Materials Co., Ltd. was founded in 1987, formerly known as Tianjin Haimen Thermal Insulation Material Factory, which was originally a military enterprise. The company is located in the Marine Development Zone of Binhai New Area, Tianjin, and the registered trademark for its products is the "Haimen" brand. The company mainly produces prefabricated buried insulation pipes, polyurethane buried insulation pipes, high-density low-pressure polyethylene outer protective pipes, buried insulation pipe fittings, steel sheathed steam buried insulation pipes, fiberglass sheathed steel insulation pipes, and steel sheathed steel insulation pipe fittings; Rock wool products, glass wool products, ceramic wool products, silicates, high-temperature insulation blankets and other insulation materials, as well as pipeline and tank insulation engineering, anti-corrosion and rust removal engineering, etc. The company has obtained ISO9001 quality management system certificate, ISO14000 environmental management system certificate, ISO18000 safety management system certificate, and other honorary certificates.
