리옹.Under the action of high welding temperature，리옹.304 스테인리스 파이프， the evaporation amount of zinc is as high as % during shielded metal arc welding. A large amount of zinc evaporation leads to the decline of mechanical properties and corrosion resistance of welded joints， and also increases the sensitivity to stress corrosion.
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.
트 롱 햄At present， 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 considering the current situation of demand and inventory in the steel market， 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 the shipment transaction is * * *.
The material of the water separator is the same， the expansion coefficient is the same， and the connection with the water separator is not easy to leak. Scope of application: As the copper pipe is more expensive than the plastic pipe， the cost of the floor heating system is higher.
구리 재료의 저장 방법에 대해 말하자면， 우리는 우리가 구입한 구리 제품을 잘 보관하고， 구리의 사용 수명을 연장하며， 그 성능을 확보하여 불필요한 손실을 피해야 한다.
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.
Corrosion caused by impure copper materials.
작은 지름 파이프의 경우 금속 채우기를 사용할 때 용접 구덩이를 채울 수 있을 만큼 길이가 파이프의 지름과 같을 수 있습니다.홍색과학보급 대 응용령역의 하나r 보드 T， 적동 막대 및 적동 파이프: 구리는 전기 및 전자 산업에서 가장 널리 사용되며 전체 소비량의 절반 이상을 차지합니다.다양한 케이블 및 전선， 모터 및 변압기， 스위치 및 인쇄 회로 기판에 사용됩니다.기계 및 운송 차량의 제조에서 산업 밸브 및 부품， 계측기， 슬라이딩 베어링， 몰드， 열 교환기， 펌프 등을 제조하는 데 사용됩니다.
품질 지표The 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， and the negotiation range is about - yuan. The overall rhythm of the market is stable and cold. In the middle of winter， the overall market in Northeast China has entered the traditional off-season， and the overall market has ended with little improvement. All companies are selling goods. The inventory level in Shenyang is very low due to the inventory clearing， and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature， the market was bleak.
After the pipe is cleaned， the welding flux and flux shall be immediately applied to the interface and the bayonet clearance. Sufficient flux shall be thinly coated on the mating surface and assembled immediately， so that dust and dirt will not pollute the capillary gap.
Because of the characteristics of copper itself it is very easy to rust and corrode in places with high ambient humihumidity. If we often use it， the problem will be smaller， but if it is placed for a long time， the copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.
With the advent of heating season， the raw material support of red copper row is weak. Under the influence of heating season and environmental protection production restriction， steel mills in some regions began to implement the production restriction measures for blast furnaces in heating season， and the demand for iron ore was weakened. In addition， the production restriction policy was issued in Tangshan today. From : on October to : on October ， the production restriction measures specified in this Notice were implemented.
포장 하 다.오늘 아침 국내 동봉 가격이 하락했다.Lange Steel의 모니터링 데이터에 따르면;중국 주요 도시의 * mm 열연대강 평균 가격은 위안으로 어제보다 원 하락했다.선물 가격이 변동하여 현물 시장 제조업체의 가격이 오늘 약간 하락했다.피드백에 따르면 시장은 주로어제를 보면 전체 거래가 막히고 주류 제조업체들이오늘 가격이 하락했다.
As theation effect of copper material on the agent is weak， the dissolved oxygen and air bubbles in it will corrode it.
만약 당신이 장기적으로 이런 상황을 피하고 싶다면， 당신은 둔화 처리를 선택할 수 있다.이렇게 하면 구리 표면이 심할 뿐만 아니라 정상적인 상태에서는 청결할 수 있지만 초음파 처리와 침포 처리 후 년 이상 공기 중에 유지하는 것은 큰 문제가 아니기 때문에 이런 효과가 매우 좋다.
리옹.파이프 벽돌 가격의 조정과 인하는 주로 환경 보호의 생산 제한과 온도와 날씨에 대한 수요가 부진하기 때문이다.최근 단말기 수요도 기온이 뚝 떨어지면서 위축돼 약세 진동을 일으키고 있다.창주 현지 무역상과의 소통에 따르면 지난주의 각종 좋은 소식으로 지난 주 동안 창주 열팽창관의 출하량이 증가해 비수기에 더 좋고 일부 규격의 출하량도 개선됐다.그러나 중소형 파이프라인 시장의 거래 분위기는 여전히 냉랭하고 수요는 점차 둔화되고 있다.상술한 바를 종합하면， 최근 창저우의 빈틈없는 강관 시장 가격은 안정 속에서 약해질 것으로 예상된다.
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， 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.
