Black Jacket Songwen Steel Pipe Manufacturer

Black jacket polyurethane insulated steel pipe manufacturer Tianze Group (Manager Bi QQ) specializes in the production of high-density polyethylene black and yellow jacket pipes (i.e., outer protective layer of insulation), prefabricated polyurethane direct buried insulation pipes (i.e., pipe foam insulation), steel sheathed steel steam insulation pipes Insulation materials such as fiberglass wrapped insulation pipes, prefabricated insulation (steel-in-steel polyurethane) pipe fittings (elbows, tees and large and small ends) are suitable for various pipeline anti-corrosion and insulation needs. Our company serves new and old customers with excellent products and low prices. We sincerely hope to establish a long-term cooperative relationship with them for mutual benefit and common development. Our company uses the imported high-pressure complete set of polyurethane foaming equipment to produce the Trinity direct-buried insulation pipes with excellent overall performance and strictly implements the rust removal treatment on the outer surface of the steel pipe and the inner surface of the outer protective pipe. The corona treatment process further improves the bonding performance of the insulation pipe. The insulation layer material is rigid polyurethane foam with a density of / to /, which fully fills the gap between the steel pipe and the casing and has a certain bonding strength to form a solid whole between the outer casing of the steel pipe and the insulation layer. Polyurethane foam has good mechanical properties and thermal insulation properties. It can usually withstand temperatures of ℃ by modification or combination with other insulation materials. Directly buried prefabricated insulated pipes have very outstanding advantages over traditional various types of insulated pipes
The thermal insulation performance is good and the heat loss is only % of traditional pipes. Long-term operation can save a lot of energy and significantly reduce energy costs.
It has strong waterproof and corrosion resistance and can be directly buried in the ground or water without the need for attached pipe trenches. The construction is simple and fast and the overall cost is low.
It also has good corrosion resistance and impact resistance under low temperature conditions and can be directly buried in underground frozen soil.
The service life can be up to 10 years. Correct installation and use can make the maintenance cost of the pipe network extremely low.
The alarm system can be set up to automatically detect leakage faults in the pipe network, accurately indicate the location of the fault and automatically alarm
Great progress has been made in the research, development and application of directly buried steel-sleeved steel steam insulation steel pipes to adapt to directly buried steam pipelines Rapidly developing market demand In recent years, our country's vast number of scientific and technical personnel and manufacturers have made great progress in the research, development and application of directly buried steam pipeline technology. No country in the world can compare with ours in terms of the diversity of insulation structural types and materials used, and the scale of engineering practice. The author has communicated with Brugge, Italy, Socksam, Germany, and many other companies in the United States many times. Their general maximum pipe diameter h is not large, and the direct pipe diameter currently used in my country's Shandong, Jinan, Hebei, Shijiazhuang, Shaanxi, Xi'an, Liaoning, Dalian, Henan, Jiangsu, and Zhejiang. The number of buried steam pipes has exceeded h and some have reached h. The insulation structure types include internal sliding and external sliding. The high-resistant insulation materials used include microporous calcium silicate, glass wool tube shell, hot-pressed perlite, silicon bead insulation material, composite silicate, etc. There are many types of insulation materials used in thermal insulation structures. Therefore, our country does not lag behind developed countries in the development and application of directly buried steam pipelines.
