The price of tube billets was adjusted and lowered mainly due to the production restriction of environmental protection and the weak demand for temperature and weather. Recently, the terminal demand has also shrunk due to the sudden drop in temperature, causing a weak shock. According to the communication with local traders in Cangzhou, various good news last week led to the shipment of thermal expansion pipes in Cangzhou in the past two weeks which is better in the off-season, and the shipment of some specifications has improved. However,Nostalier40Mn2 alloy steel plate, the trading atmosphere in the small and medium-sized pipe market is still cold, and the demand is slowing down gradually. To sum up, it is expected that the market price of Cangzhou seamless pipe will be stable and weak in the near future.When stacking, it shall be stacked reasonably and placed first.Nostalier,Try to avoid using radiator copper pipes in hot water circulation pipelines to reduce the possibility of corrosion. If copper pipes are used as circulation pipelines, pipeline maintenance space should be reserved.The main force of iron ore futures closed at in The closing price of the day today was the same as that of the previous trading day, including * * * * , * * * , settlement price , trading volume , and position volume . The intraday tradg volume decreased by compared with the previous trading day, and the position volume decreased by compared with the previous trading day. After six consecutive days of downward adjustment, but it was corrected again later, and the closing was flat.Mahabad,The price of pig iron market rose by - yuan this week, and the transaction was fair. With the increase of coke price,Nostalierbrass plate, the cost of ductile iron in Shanxi, Henan, Liaoning, Shandong and other regions has increased. In addition, with the gradual release of downstream demand, the inventory of iron plants is not large, and iron plants have successively raised their prices. There are few iron foundries in Shandong, Jiangsu, Hebei and Shanxi, and the inventory remains low. As the coke price rises and the cost increases, the price of iron foundries rises again.Disadvantages: low output, high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation, which is the development direction of copper tube industry in the future.The excellent performance of copper pipe The copper pipe has the characteristics of and, which makes it a suitable choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial housing.

It has excellent conductivity, thermal conductivity, ductility and corrosion resistance.Copper pipes of different models shall be stacked separately.Four of the five major application fields of copper plate, copper bar and copper pipe: copper is used as various pipes, pipe fittings and decorative devices in the construction industry.Affordable price,Three of the five major application fields of copper plate, copper bar and copper tube: copper is used to manufacture, and gun parts in the national defense industry. Every million rounds of copper are produced, - tons of copper are needed.The copper tube shall be heated and welded first, and then the joint shall be heated until the heated part turns dark red. At this time, the filler metal shall melt.Save materials and total cost, stability and performance, and can save maintenance.

Generally, oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.Quality documents,Safe and reliable: copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold drawn copper pipes is equivalent to that of steel pipes with the same waess); It is also easier to bend than ordinary metals, has good toughness and high ductility, and has excellent anti vibration anti impact and anti frost expansion properties.Corrosion caused by water flow rate and flow.The application of copper tube The copper tube is generally used in the heat exchange equipment, and the low-temperature pipeline in the oxygen production equipment can also be used. Some relatively thin copper tubes can be used to transport some pressurized liquids, and can also be used as pressure measuring tubes in instruments; In addition, the copper pipe is relatively firm unlike other metals, which are easily corroded so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.Nostalier,Three of the five major application fields of copper plate, copper bar and copper tube: copper is used to manufacture, - tons of copper are needed.The second of the five application fields of red copper plate T, red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels, distillation pots, brewing pots, thermal conductivity, ductility and corrosion resistance.
