Disadvantages: Due to loose tissue and high pressure resistance，엔 하 타 만합금판， the pipe is only used to produce small air conditioning copper rods.
Copper pipe has the characteristics of， and is the choice for the installation of water pipe， heat supply and refrigeration pipe.
엔 하 타 만Corrosive agents such as calcium bicarbonate， inositol hexaphosphate， silicon phosphate crystal etc. are added to the water to regulate the PH value of the water and the corrosion symptoms.
[] Welding process of copper pipe Clean the end and seven ports of steel pipe with steel wool. Do not use abrasive cloth or abrasive paper to clean， because it will affect the clean interface and result in poor welding effect.
나 무 르그것은 우수한 전도성， 열전도성， 연전성과 부식성을 가지고 있다.

이번 주 양철 시장 가격은 - 위안 상승했으며 거래는 공정합니다.코크스 가격이 상승함에 따라 산시， 허난， 랴오닝， 산둥 등 지역의 잉크 주철 원가가 다소 증가하였다.이밖에 하류의 수요가 점차 방출됨에 따라 강철공장의 재고량이 크지 않아 강철공장이 륙속 가격을 인상했다.산동， 강소 하북과 산서의 주철공장은 아주 적고 재고는 여전히 매우 낮다.코크스 가격이 오르고 원가가 증가함에 따라 주철공장의 가격이 다시 올랐다.
In consideration of the above factors， more and more steel plants have stopped production since October， and the production limit in Wuan and Tangshan heating seasons has been advanced. In addition， the formal implementation of production limit in "+" urban heating seasons after November by steel enterprises， the demand for iron ore in the future is likely to further deteriorate. The iron ore inventory of the steel plant is relatively high，엔 하 타 만201 스테인리스 강판， and the willingness to further replenish the inventory is not strong. In terms of supply， the quantity of * * * is relatively limited. In general， the short-term iron ore market may lack upward momentum.
동관 부식 원인: 공기 오염.
So far as the storage method of copper materials is concerned， we should properly keep the copper products we buy， extend the service life of copper and ensure its performance to avoid unnecessary losses.
품종 이 완비 되다Although the opening continued the weak trend， the intraday transactions improved， and the prices of some copper bar manufacturers rose. From the specific situation although the manufacturer feedback that the shipment is average， the mentality is relatively calm，엔 하 타 만스테인리스강 용접관， the market inventory is not much， and the manufacturer is not willing to significantly reduce the price. In terms of the market， the transaction of strip steel is better than other steel varieties， and the downstream mainly focuses on callback buying without panic inventory clearing. It can be seen that although the steel market continues to shake， the overall demand for strip steel remains in a good state.
동판， 동봉과 동관의 다섯 가지 주요 응용 분야 중 네 가지: 동은 건축업에서 각종 파이프， 파이프와 장식 장치로 사용된다.
When stacking， it shall be stacked reasonably and placed first.
The hard copper tube is not artificially treated after being drawn or extruded， so that it can be naturally formed. At this time， 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.
생산 업 체압출법: 본 생산 방법은 정련 후 구리 주괴를 주조하고 차 가열 후 대형 압출기로 구리 파이프를 압출한다.
그래서 카자흐스탄에 가는 일부 ah 환열기의 산소 설비에 자주 사용된다.
The excellent performance of copper pipe The copper pipe has the characteristics of and， which makes it a suitable choice for modern contractors to install water pipes， buses， cables， switchgear， transformers， 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".
