The ex factory price of Linyi Pipe Factory has decreased by yuan for cash Baocheng ( * mm， yuan for Jin Zhengyang yuan， yuan for Ruigang Lianlian， yuan for Meixin yuan， and yuan for Taizong yuan.
아 리 시First of all， brass pipe is a non-ferrous metal pipe， which can generally be used as a water pipe. Because this pipe product is a seamless product， it can effectively prevent water pipe leakage. Of course， because this kind of copper tube product has its own hardness and good corrosion resistance， it can also be used as heating and cooling tubes. The brass tube not only has good corrosion resistance and hardness， but also has strong plasticity. Compared with other metal pipe products， this kind of pipe has the characteristics of bending， inversion， and not easy to break. This kind of pipe product is widely used in daily life and has a longer service life.Brass pipes have strong frost heave resistance and impact resistance. Copper pipe products with these advantages have a long service life and can play an important role in building water supply systems. In short， as long as this copper tube product is installed， it is safe and reliable， and even does not need maintenance.
자재 및 총 비용， 안정성 및 성능 및 유지 보수 비용 절감
샌 안 드 레When welding， just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.
Copper pipe has the characteristics of， and is the choice for the installation of water pipe， heat supply and refrigeration pipe.
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.
단점: 생산량이 낮고 생산 원가가 높으며 가격이 높다.압출 동관 공예는 현재 국내외의 안정적이고 우수한 동관 생산 방법이다.오직 이런 공예로 생산한 동관만이 난방분야에 더욱 적합하며 이는 동관업종의 미래의 발전방향이다.
Try to avoid using radiator copper pipes in hot water circulation pipelines to reduce the possibility of corrosion. If copper pipes are used as circulation pipelines，아 리 시45# 원강， pipeline maintenance space should be reserved.
Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.
고 품질When stacking it shall be stacked reasonably and placed first.
At the opening this morning， the market price of Zhengzhou copper bar was basically stable. According to the monitoring data of the Lange cloud business platform， the current market price of * mm Linyi copper bar was yuan (ton price， the same below)， the * mm copper bar was yuan， and the * mm copper bar Henan copper bar was yuan.
장점: 품질이 좋고 구조가 정교하며 밀도가 높고 내압성이 높으며 구부러지고 변형이 크며 빈번한 냉열교환에 적합하고 작업환경의 온도차가 크며 큰 사이즈의 동관을 생산할 수 있다.
It is mainly used to manufacture electrical devices such as generators，아 리 시60SI2MN 합금 원강， buses， cables， switchgear， transformers， and thermal conductive devices such as flat plate collectors for heat exchangers， pipes， and solar heating equipment. Common copper alloys are divided into three categories: brass， bronze and white copper. Pure copper plate is a purplish red metal， commonly known as "copper plate"， "red copper plate" or "red copper plate".
대리상동관은 일종의 비철금속관으로서 압제하고 늘어나는 무봉관이다.동관은 열전도성이 뛰어나고 견고하며 부식에 강하다.환경 온도에 비해 갈라지지 않기 때문에 모든 주택 분양주택에 수도관， 난방관， 냉동관을 설치하는 것이 현대 하청업체의 우선순위가 되었다.
수질을 재처리하다.
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， from the perspective of the policy port of the steel plant， the overall production situation of Nangang， Hengrun， Dada， 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.
아 리 시The 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， with the gradual release of downstream demand， 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.
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，아 리 시빨간 동봉， which is the development direction of copper tube industry in the future.
Safe 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， has good toughness and high ductility， and has excellent anti vibration， anti impact and anti frost expansion properties.
