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.
신 길 달The market opened today. Although the performance of Zitong Pai futures was modest， the overall market has stopped. The market mentality has not changed much sincekend. The price is stable，엘 치T2 동갈비， but some specifications are subject to negotiation， and the negotiation range is about - yuan. The overall rhythm of the market is stable and cold.

Insert the pipe into the top of the bayonet，e the sleeve on the pipe to evenly apply the flux on the joint， and confirm that the pipe is inserted into the bottom of the socket， then wipe off the excess flux， and the joint is assembled and can be heated.
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.
만약 동관을 사용하는 과정에서 막힌다면 제때에 소통시키는 것도 매우 중요하다.
Red copper bars in other regions basically follow the price trend of Tangshan， in which the bid of Jiangsu Steel Works tends to be higher， and the overall market transaction is fair. The steel mills in Wuan are limited in receiving orders， and the market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary， and it is difficult to clinch a deal. The willingness of downstream customers to receive orders is weak， so they hold a cautious wait-and-see attitude. At prepresent， the steel market is in the "golden third" peak season. The market has a good expectation of the future market and a strong willingness to support prices. It is expected that the prices of Tangshan mainstream billets will be stronger next week.
품질 관리Generally， 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.

시장가 격It can be wrapped with moisture-proof paper for moisture-proof protection. It can also prevent oxidation to a certain extent. If cracks or serious corrosion are found， they must be isolated.
First of all， brass pipe is a non-ferrous metal pipe， which can generally be used as a water pipe. Because this pipe product is a seamless product， it can effectively prevent water pipe leakage. Of course， because this kind of copper tube product has its own hardness and good corrosion resistance， it can also be used as heating and cooling tubes. The brass tube not only has good corrosion resistance and hardness， but also has strong plasticity. Compared with other metal pipe products， this kind of pipe has the characteristics of bending， inversion， and not easy to break. This kind of pipe product is widely used in daily life and has a longer service life.Brass pipes have strong frost heave resistance and impact resistance. Copper pipe products with these advantages have a long service life and can play an important role in building water supply systems. In short， as long as this copper tube product is installed， it is safe and reliable， in the steel plant the lock price of the steel plant has been falling all the time， and the order receiving is poor. The capacity utilization rate of the steel plant is low， but the market is still in oversupply. The stock of the steel plant and the spot stock are both risirising， so the market price has fallen sharply. Subsequently， the futures market rebounded in a wave， and the spot price also increased with the increase. There was an instant of large volume of transactions. However，엘 치310s 스테인리스 스틸 무봉관， with the decline of black futures， the market transaction volume shrank significantly. In addition， the inventory pressure was high， traders shipped at low prices， and the spot price fell under pressure. Due to the strong drop resistance of medium and thick plates， the drop amplitude and rate are less than those of threads.

According to the monitoring data of Lange Steels cloud business platform， the average price of * mm hot rolled strip in key cities in China is ， down yuan from yesterday. Futures prices fluctuated， the market was mainlysee yesterday， which caused the overall transaction blocked， and the mainstream manufacturers prices fell today.
