Manufacturer of large-diameter insulated steel pipes for building heating

Cangzhou Tianyuan Anti-corrosion Engineering Co., Ltd. Zhang
Large-diameter insulated steel pipes are generally used in heating, water supply and drainage in municipal and major buildings. It is an insulation material with high adhesion, impact resistance, anti-corrosion and weather resistance on the outer wall. br/> Wall coating with high adhesion, anti-corrosion thermoplastic powder coating. It is made by sandblasting chemical dual pre-treatment, preheating, inner coating, outer coating, curing, post-treatment and other processes.
Large-diameter insulated steel pipes have smooth pipe walls, good drainage performance, low fluid resistance, and no scaling, which are major advantages compared to other pipes and can greatly reduce losses.
At the same time, the linear expansion coefficient of large-diameter insulated steel pipes is very small, which makes it very advantageous as a trunk water pipe, which greatly overcomes the shortcomings of large linear expansion coefficients of other plastic and ordinary pipes. Large-diameter insulated steel pipes are cost-effective upgrades to traditional steel-plastic pipes and galvanized pipes. It has comprehensive characteristics, including the high strength, high elongation, good low-temperature brittleness, and small expansion coefficient of steel pipes, as well as the corrosion resistance, wear resistance, and low fluid resistance of plastic pipes. It is a new type of feed pipe. Drainage and anti-corrosion green large-diameter pipes are increasingly widely used by various domestic industries.
Anti-corrosion and insulated steel pipe refers to the insulated steel pipe that ensures the internal temperature and surface temperature of the working steel pipe at the same time in different working environments to slow down or prevent the chemical and electrochemical effects of the external medium or the metabolic activities of microorganisms And the insulation and anti-corrosion measures that are eroded and deteriorated.

Tianyuan anti-corrosion, anti-corrosion and insulated steel pipes can be equipped with an alarm system to automatically detect leakage faults in the pipe network, accurately indicate the fault location and automatically alarm.
Products are widely used in many industries such as electric power, chemical industry, pharmaceuticals, oil refining, natural gas, shipbuilding, metallurgy, mining, insulation pipelines, heating pipelines, water treatment, environmental protection, etc.
Polyurethane Insulated Steel Pipe Looking at the world, the polyurethane industry in Western developed countries has already entered a mature development period and entered the stage of innovative research and development. The Asian market is growing rapidly
Many multinational chemical companies have established their business focus and R&D centers. Shifting to Asia and even the Chinese market. The development of the polyurethane market in the Middle East is still in its infancy. Generally speaking, due to the rapid development of the national economy in the past decade or so, China's polyurethane industry, including basic raw materials to products and machinery and equipment, has reached considerable scale. In 2017, China's polyurethane output was approximately 10,000 tons, with an output value of approximately 100 million yuan, an increase of % and % respectively over the 10,000 tons and approximately 100 million yuan in 2015. The average annual growth rate of output was as high as %, and the average annual growth rate of output value was as high as %. The rate is above %. At present, many Chinese and foreign companies have been involved in the polyurethane industry for polyurethane insulated steel pipes. In the past ten years, although China's average annual growth rate of polyurethane has been twice that of D, China's per capita consumption of polyurethane has not yet reached the world average. The annual per capita consumption of MD in China is .kg, while the world average
is .kg. Calculated based on per capita D development and polyurethane growth rate, China's polyurethane industry is still in a period of rapid growth. In the future, the development of China's polyurethane industry will
be mainly driven by five major aspects, namely the total population, the automobile industry, building energy conservation, the improvement of environmental protection requirements, and the leisure and entertainment industry. During the 11th Five-Year Plan period, China's U product consumption
will maintain an average annual growth rate of 10%. By then, China will be the world's largest U product manufacturing and consumption center.
Domestic Iron Ore The market performance stabilized and transactions improved slightly. The National Day holiday is less than two weeks away, and some steel companies are more willing to stock up before the holiday. In addition, the iron ore resource inventory in the factories of some steel companies has always been at a low level. As a result, the overall demand for iron ore resources is strong. , slightly supporting iron ore prices, and iron ore spot prices remain stable in the short term. The domestic steel market has stopped falling. Today, the billet market price in Tangshan has rebounded by 100 yuan, and the downstream transaction situation has improved slightly. Affected by the steady recovery of the steel market, the demand for iron ore resources by steel companies has not yet has weakened, but the enthusiasm for pre-holiday purchasing is still acceptable. Today, the main iron ore futures contract of DCE also rose, touching the
yuan mark. This is a quite obvious rise since the decline at the end of the month, closing at . yuan or .%. Comprehensive factor analysis shows that in the short term, the iron ore market will be supported by demand and downstream markets, and the overall price will remain stable. The possibility that some merchants may take the opportunity to raise prices cannot be ruled out.
The mainstream market price of % acid powder wet basis in Tangshan area excluding tax is yuan, which remains stable. The market price of %% acid powder wet base in Jianping area, excluding tax, is at yuan,
stable. The cash market price of %% acidic dry base in Zibo including tax is yuan, which is stable. The reference price of .% Australian powder in the imported ore external market is .USD, which remains stable. In Qingdao Port, the reference price of % Australian powder is yuan, which is stable, and the reference price of % Mac powder is yuan, which is stable. Tianjin Port.%B Australian powder reference price is RMB, which remains stable
. Super special powder reference price is RMB, which has been adjusted around RMB.
Hangzhou Structural Steel: The market price of Hangzhou structural steel is temporarily stable today. At present, the mainstream quotation of Hangzhou Iron and Steel Co., Ltd.'s carbon round is RMB/ton, and the mainstream quotation of Huaigang is RMB/ton in Nanjing Steel Resource Market
The quotation of Yuanli Resource Factory is RMB/ton. The listing price of Dongfang Special Steel's carbon structural steel in the Hangzhou market is yuan/ton. Zhongtian Steel's small rods are carbon today
The listing price of the structural steel h steel plant is yuan/ton. In terms of transactions: the transactions of large households were in tons, and the transactions of small and medium-sized households were in tons. There was little change compared to the previous trading day. In the short term
, prices may continue to show a downward trend after a short adjustment. In addition, steel mills such as Huaigang will introduce a new round of price policies tomorrow, and the market is expected to drop more than yuan/ton
.
Changzhou and Nanjing Structural Steel: The price of structural steel in the Changzhou and Nanjing markets has loosened today. The current quotation of carbon structural steel at Huaigang in the Changzhou market is RMB/ton, and the quotation of Nanjing Steel in the Nanjing market is
yuan/ton. Changzhou: The market shipments were average yesterday, with Changzhou Hangzhou Iron and Steel International Trade Co., Ltd. shipping tons and Changzhou Yilian tons. Nanjing: Nanjing Steel Plant has relatively complete resources recently, and merchants' shipments are light. Today's market prices have fallen. First, merchants want to exchange price for volume to complete the agreed volume. Second, they hope that the next round of steel mills' price adjustments will reduce the price. slightly larger.
