Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.
The conductive production of copper tube is the latest method for this method. It is the production of nanocrystalline copper materials with conductivity. Because this raw material is very special， it is a copper material produced by using nanotechnology， and copper ions can be separated by conductivity， so that copper tubes can be produced with the separated copper ions. This method is very complex， requires high technology and new equipment， so only advanced foreign countries can use this production method.

광명.개장과 함께 약세 흐름을 이어갔지만 일내 거래가 개선돼 일부 동봉 제조업체의 가격이 올랐다.구체적인 상황을 보면， 비록 공장이 출하량이 보통이라고 피드백했지만， 심리 상태는 상대적으로 평온하고， 시장 재고가 많지 않으며， the fundamentals faced by the domestic copper bar market are still mixed. On the one hand， the market supply is expected to shrink， but on the other hand， the northern market has entered the off-season of demand， and the markets expectation of future demand is pessimistic. In the short term， domestic steel prices will enter the operating track of range consolidation. To sum up， it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching， environmental protection phenomena such as steel mills are still going on， and black series speculation is still taking place. But personally， the fluuation range of the market in this region is limited， and businesses can operate flexibly on a short-term basis， and the shipment transaction is * * *.
To sum up due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants， the gradual emergence of supply and demand pressure， and the weakness of raw material support， among which the contraction of market demand has a greater impact. Therefore， the author believes that in the short term， the spot building materials do not have the possibility to rise significantly， and the price of building materials may mainly operate in shock， but with the shrinking demand， the supply and demand pressure becomes prominent， However， considering the influence of winter storage and other factors， it is still possible for merchants to lower the spot price in November.
In terms of steel billets: at :， some steel billets in Changli were reduced by ，선명 하고 아름답다.6063 알루미늄 튜브， and the current carbon square billets were delivered with tax of yuan. After the th National Congress of the Communist of China， there was no unilateral market for either futures or cash it can be seen that at this stage， and there was no definite pattern of ups and downs.According to the monitoring data of Lange Iron and Steels cloud business platform， as of the time of publication， Tianjin Youwelded Line: the steel mill reported: Rongcheng # yuan/ton， B yuan/ton; Jiujiang # - # to Tianjin yuan/ton; The arrival price of Xinji Aosen # is yuan/ton， and that of B steel is yuan/ton; Jiyuan # yuan/ton， B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton， B steel yuan/ton.
구리 파이프는 가공과 연결이 쉽기 때문에 재료와 총 비용， 안정성 및 신뢰성을 절약할 수 있으며 설치 과정에서 유지 보수를 절약할 수 있습니다.
단점: 조직이 느슨하고 고압에 강하기 때문에 이 파이프는 소형 에어컨 동봉 생산에만 사용된다.

This week (-， the market price of red copper bar rose， and the transaction was not ideal. On the bidding day of Shagang last weekend， the price was stable to support the market， and the rising of billets at the weekend drove the market up in a wave， and the price of variety wire rods also rose by yuan at the weekend. However， it was reported that the deal was very poor which led to the price being stable for the next two days. Until Wednesday， due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving， the market lowered the price. Market price changes， Xinji rose yuan on the rd; For the future market， the off-season is coming， the demand is weakening， the environmental protection inspection is becoming more and more strict， which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.
