구리 표면의 부식이 경미한 것으로 발견되면 리넨 동선으로 지울 수 있지만 기름을 발라 방부하는 것은 권장되지 않는다.
Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand， the continuous decline of iron ore port inventory may end. In addition， according to the new statistics of * *， the available days of imported iron ore of steel mills are days， and is on the high side of history. The steel mill said that at present， the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction， the steel mill is not willing to replenish the inventory.
델 너완제품은 반드시 실내에 보관해야 한다.저장 기간에는 햇빛이 동관을 직사하는 것을 방지해야 한다.동관의 이전， 운송 및 하역 과정에서 비가 오는 것을 피해야 한다;여름철 동관 환경은 온도가 높아 동관 표면의 속도가 빨라진다.동관을 보관할 때는 선진적인 선출의 원칙에 주의하여 손실을 줄여야 한다;구리 파이프를 적재하는 과정은 실내에서 진행하는 것이 가장 좋으며， 구리 파이프가 햇빛에 노출되지 않도록 하여 구리 파이프 외벽의 속도를 높이는 것이 좋다.적재가 완료되면 최소 두 겹의 캔버스를 사용하여 완성차 재료를 단단히 싸야 한다;적재 후 트럭이 제때 떠나지 못하면 화물이 장시간 햇빛에 노출되어 열을 흡수하는 것을 막기 위해 트럭을 햇빛 뒤로 몰아야 한다.

미 슈 카 포In the first ten days of May， the overall order receiving quantity of Tianjin Hebei Henan Plate Plant was not ideal. According to the monitoring data， the overall order intake of medium and heavy plate mills in Tianjin Hebei Henan region in the first ten days of May remained stable and weak. Due to the weak market shock， the overall order intake of the spot steel market was relatively weak. The total quantity of orders received in the first ten days of May is only about tons， while at the end of April， the total quantity of post settlement agreements of main steel plants can exceed tons.
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 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.
단점: 조직이 느슨하고 고압에 강하기 때문에 이 파이프는 소형 에어컨 동봉 생산에만 사용된다.
동관은 견고하고 부식에 견디는 특징을 가지고 있어 수도관 난방관과 냉동관 설치의 첫 번째 선택이다.
I dont know how to keep the copper tube.

상술한 바를 종합하면， some iron plants do not take orders temporarily. The steel mills in Liaoning have increased their enthusiasm for purchasing steel. The iron mills have delivered well， and the price of raw materials has risen， so the iron price has risen. The iron mills have a high enthusiasm for producing steel， so there is not much cast iron resources， and the price has risen. A few steel mills in Tangshan began to purchase a small amount of steel for smelting， and most steel mills are still on the lookout for inquiry. Under the background of increasing cost and gradual release of demand，델 너합금 강판， the pig iron market is performing well and is expected to continue to operate strongly in the short term.

델 너Three 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.
Disadvantages: Due to loose tissue and high pressure resistance， the pipe is only used to produce small air conditioning copper rods.
