단점: 조직이 느슨하고 고압에 강하기 때문에 이 파이프는 소형 에어컨 동봉 생산에만 사용된다.

The hard copper tube is not artificially treated after being drawn or extruded， the organizational form in the copper tube is full. This kind of copper tube is more likely to crack and is not suitable for bending. Therefore， the hard copper tube is generally straight.
Disadvantages: low output， high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation， which is the development direction of copper tube industry in the future.
Tangshan billets rose sharply last weekend steel mills in some northern cities implemented production restriction， and some domestic economic data improved， which boosted manufacturers confidence. Today， steel prices generally rose. However， with the approaching meeting and the rainfall in the south caused by the typhoon， the construction progress of the downstream construction site is affected， which is not conducive to the continuous demand. The high spot price transaction today is weak， which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow， and some businesses may reduce prices and take goods.
The copper tube welding process is to radiate the copper tube bundle with excellent directivity， high brightness， high strength， high monochromaticity， high coherence and other characteristics to the surface area of the workpiece to be processed. After the copper tube bundle is focused by the optical system， through the interaction between the copper tube and the object to be welded， a highly concentrated heat source area can be formed at the place to be welded in a very short time. The heat energy makes theea to be welded melt， cool and crystallize to form a solid welding spot and weld seam.
The price of pig iron market rose by - yuan this week， and the transaction was fair. With the increase of coke price， the cost of ductile iron in Shanxi， Henan， Shandong and other regions has increased. In addition， the inventory of iron plants is not large， and iron plants have successively raised their prices. There are few iron foundries in Shandong， Jiangsu， Hebei and Shanxi， and the inventory remains low. As the coke price rises and the cost increases， the price of iron foundries rises again.
얼마Safe and reliable: copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold drawn copper pipes is equivalent to that of steel pipes with the same waess); It is also easier to bend than ordinary metals，대대.6061 알루미늄 튜브， has good toughness and high ductility， and has excellent anti vibration， anti impact and anti frost expansion properties.

In Jiangyin market， another distribution center， the overall inventory of the current circulation link is about tons， slightly lower than the normal level. At the beginning of this week， the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However， from the perspective of the policy port of the steel plant， the overall production situation of Nangang， Hengrun， etc. is relatively normal， and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons， which is a medium normal level， and the recent spot price of Lecong market has a large gap with that of the north.

탁월 한 서비스Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.
Use qualified copper raw materials for production， try to avoid using the pipe body produced by recycled copper reduce impurity corrosion， and extend the service life of copper pipe.
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.

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.
