In August， the price of domestic medium and heavy plates fell sharply. As of August ， the price center of ordinary carbon boards in leading cities had dropped to ， down yuan/ton from the end of July. At the beginning of the month， affected by the macro bad news， and the recent poor performance of fundamentals， the market mentality turned to pessimism and some traders shipped at low prices. The market inventory rose， the stock shortage phenomenon disappeared the inventory pressure was high and the market transaction atmosphere was cold， the demand performance continued to decline， and the spot price fell under pressure.
주로 발전기， 모선， 케이블， 스위치설비， 변압기 등 전기설비와 열교환기， 도관과 태양에네르기가열설비의 평판집열기 등 열전도설비를 제조하는데 사용된다.흔히 볼 수 있는 구리합금은 황동， 청동， 백동 세 종류로 나뉜다.순수한 동판은 자홍색 금속의 하나로， 일반적으로 & amp; 라고 부른다.quot；동판 & amp;“&；quot；적동판 & amp;quot；또는 "；적동판 & amp;”；.
조 보.동관을 어떻게 저장합니까?구리 파이프의 우수한 성능을 환경으로부터 보호하기 위해 우리는 다음과 같은 몇 가지를 해야 한다. 첫째， 적합한 장소와 창고를 선택하고 주변 환경을 건조하고 통풍시켜야 한다.산， 알칼리， 시멘트 등과 함께 쌓아서는 안 된다.
퇴화 적동판의 실온 인장 강도는 ~kgf/mm이고 신장률은 ~%이며 부씨경도(HB)는 ~이다
샌 안 토 니 오 델 타 키 라Copper tube is a kind of nonferrous metal tube， which is pressed and drawn seamless tube. The copper pipe has good thermal conductivity， and is solid and corrosion resistant. It will not crack when compared with the ambient temperature so it becomes the first choice for modern contractors to install the water pipe， heat supply pipe and refrigeration pipe in all residential commercial houses.
The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm， the elongation is ~%， and the Brinell hardness (HB) is ~
연동관의 생산 방법은 경동관과 기본적으로 같다. 즉 경동관에 비해 퇴화 공정을 증가시켰다.동관의 퇴화는 그들이 고온로에서 하소하여 동관의 원소의 배열을 바꾼다는 것을 의미한다.그러나 불이 꺼지면 구리 파이프가 부드러워져 더 쉽게 구부러집니다.이런 방식으로 생산된 동관을 소프트 동관이라고 한다.
Some steel mills in Liaoning are interested in purchasing pig iron， but the local resources are tight， and the iron mills quotations are on the high side， resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu， Shandong， Hebei， Henan and other regions is sluggish， and the inventory pressure of iron mills is increasing. As the price of raw materials decreases， the quotation of iron mills continues to decline. At present， the demand and cost support are weak， and there is no positive boost. The short-term pig iron market is weak and difficult to change.antages: 낮은 생산 비용과 높은 생산성.
For internally threaded tubes with the same inner diameter， the thickness of feus metal is not required for copper tubes.
The copper tube shall be heated and welded first，조 보.합금판， and then the joint shall be heated until the heated part turns dark red. At this time， when the filler metal contacts the tube， the filler metal shall melt.
특혜Advantages and scope of application of copper tube ground heating At present， ground heating is not only a comfortable heating method， but also a symbol of modern life quality. More and more houses， public buildings， sports facilities， industrial facilities and other places begin to use ground heating radiator， which is an important part of ground heating. Due to the corrosion resistance of copper， copper tubes are selected as the main material of radiator in many places.
In view of the current overall price difference， the local copper bar price continued to rise at a high level today， while the regions outside East China did not show an obvious follow-up trend， and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction， and the price support of copper bar is still strong. However， at present， domestic real estate control is still being tightened. The markets expectation of future demand is weakening， and the markets fear of heights appears after the price rises.Today， the market price of copper bars in Shenyang is stable and the shipment is poor.
Advantages: good quality， fine structure， high density， high pressure resistance， large bending deformation， large temperature difference in working environment，조 보.구리 알루미늄 복합 배출， and large size copper tube can be produced.
Save materials and total cost， stability and performance， and can save maintenance.

데이터 정리를 잘하다.
동관의 단점은 동관의 경우 높은 생산 원가와 높은 가격이 가장 큰 단점이다.다른 파이프 부품에 비해 구리 파이프의 원가가 훨씬 높고 구리 파이프 인터페이스의 연결은 비교적 높은 시공 기술 수준을 요구한다.
조 보.The market price of Zhengzhou copper bars is basically stable， and the shipment is not good. In terms of tube blank: today， Shandong Luli tube blank slightly reduced by yuan， and the current mainstream ex factory price is - yuan. In terms of pipe plant: Linyi Pipe Plant locked the price for a week. With a stable market mentality， the factory price of hot rolled seamless pipes is now between - yuan. On the market side: with the arrival of the off-season， traders generally ship goods at a high price. Replenishment is mainly to maintain the existing inventory， and the market price of Zhengzhou copper bar is expected to be stable and declining.
In the morning trading today， the price of domestic copper bar fell. 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， and the prices of spot market manufacturers eased slightly today. According to the feedback，조 보.알루미늄 냉동창고， the market was mainlysee yesterday， which caused the overall transaction blocked， 모선， 케이블， 스위치설비 변압기 등 전기설비와 열교환기， 도관과 태양에네르기가열설비의 평판집열기 등 열전도설비를 제조하는데 사용된다.흔히 볼 수 있는 구리합금은 황동， 청동， 백동 세 종류로 나뉜다.순수한 동판은 자홍색 금속의 하나로， 일반적으로 & amp; 라고 부른다.quot；동판 & amp;“&；quot；적동판 & amp;quot；또는 "；적동판 & amp;”；.
