세 가 마 트외부 포장은 표면의 긁힘， 균열 및 기타 손상을 방지할 수 있습니다.
수분 분리기는 재료가 같고 팽창 계수가 같아 수분 분리기와의 연결이 잘 새지 않는다.적용 범위: 구리 파이프가 플라스틱 파이프보다 비싸기 때문에 난방 시스템의 비용이 더 높습니다.
코트 리장점: 품질이 좋고 구조가 정교하며 밀도가 높고 내압성이 높으며 구부러지고 변형이 크며 빈번한 냉열교환에 적합하고 작업환경의 온도차가 크며 큰 사이즈의 동관을 생산할 수 있다.
The copper tube shall be heated and welded first， 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.
동관 지온의 장점과 적용 범위는 현재 지온은 편안한 난방 방식일 뿐만 아니라 현대 생활의 질의 상징이기도 하다.갈수록 많은 주택， 공공건축， 체육시설， 공업시설 등 장소에서 지온라디에이터를 사용하기 시작하는데 이는 지온의 중요한 구성부분이다.구리의 내식성 때문에 많은 곳에서 구리 파이프를 라디에이터의 주요 재료로 선택한다.
파이프를 청소한 후에는 즉시 인터페이스와 카드 사이에 용접제와 보조용접제를 발라야 한다.배합면에 충분한 용접제를 얇게 바르고 먼지와 때가 모세관 간극을 오염시키지 않도록 즉시 조립해야 한다.
장점: 투자 원가가 낮고 생산 원가가 낮으며 생산량이 높고 가격이 낮다.
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.
편리 하고 효율 적 이다.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，세 가 마 트빨간 동봉， 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.

Statistics show that the iron making capacity of Handan in was million tons and the steel making capacity was million tons.
The composite method of three production methods of copper tube is also a high-tech production method for this method. It is a copper material containing impurities. Those copper materials， copper alloys and composite copper materials are put together by electrochemical reaction to produce a nanocrystalline copper material and then the material is purified to produce copper tube materials.
발전 과정It 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.
으로구리 재료는 약제의 부식 작용이 비교적 약하여 산소와 기포를 용해하면 약제를 부식시킬 수 있다.
It has excellent conductivity， thermal conductivity， ductility and corrosion resistance.
세 가 마 트This week (-， 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.
