In addition， it is not easy to be corroded and can adapt to various environments. It can be used normally at low and high temperatures， 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.

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.
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.
Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.
Air conditioning copper tube production technology Upward lead method: This production method is electrolytic copper after copper tube is directly melted.
쌓을 때는 합리적으로 쌓고 우선적으로 놓아야 한다.
우세 적 자질In terms of steel billets: at :， some steel billets in Changli were reduced by ， and the current carbon square billets were delivered with tax of yuan. After the th National Congress of the Communist of China，과 라 콘 사스테인리스강 용접관， the market had doubts about the uncertainty of environmental production restriction and was still waiting for a clearer direction. Therefore， it can be seen that at this stage， there was no unilateral market for either futures or cash， and there was no definite pattern of ups and downs.According to the monitoring data of Lange Iron and Steels cloud business platform， as of the time of publication， Tianjin Youwelded Line: the steel mill reported: Rongcheng # yuan/ton， B yuan/ton; Jiujiang # - # to Tianjin yuan/ton; The arrival price of Xinji Aosen # is yuan/ton， and that of B steel is yuan/ton; Jiyuan # yuan/ton，과 라 콘 사알루미늄관， B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton， B steel yuan/ton.
구리 재료의 저장 방법에 대해 말하자면， 우리는 우리가 구입한 구리 제품을 잘 보관하고， 구리의 사용 수명을 연장하며， 그 성능을 확보하여 불필요한 손실을 피해야 한다.
자동관의 장점 내구성: 구리는 안정적인 화학재산을 가지고 있으며 내한， 내부식과 내화를 일체화하여 서로 다른 환경에서 장기적으로 사용할 수 있다.
용접할 때는 모세관 간격을 채우기 위해 충분한 필러 금속을 추가하기만 하면 됩니다.너무 많은 채우기 금속은 조인트 하단에만 구를 형성하거나 파이프로 유입됩니다.

Red copper inventory in key areas has risen continuously 내압， but the total pressure is not big. From the current overall inventory situation of the main distribution centers Wuan， the inventory level remains relatively moderate， and the pressure on the market is relatively small. In Wuan market， according to the data， as of May ， the total inventory of medium and thick plates in Wuan was close to tons increasing by tons on a weekly basis. In late April， it reached tons lower in the year， down tons from the high level after the Spring Festival and rose for three consecutive weeks. In terms of the ovquantity， it should be said to maintain a relatively moderate level.

Remove the flame. If the filler metal does not melt， continue to heat the joint and try again. The melted filler metal is sucked into the casing port according to the capillary effect until a complete filler metal ring appears on the casing port. Remove the flame Pay special attention not to let the flame directly contact the filler metal. It should be the heat at the joint that melts the filler metal. In order to clean the copper pipe， the welding flux must have a degree of corrosivity， and shall be cleaned after brazing. The so-called "self-cleaning" fluxes are generally not recommended because of their corrosivity.
The blowpipe shall be perpendicular to the lead pipe during welding， and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.
