Insert the pipe into the top of the bayonet，e the sleeve on the pipe to evenly apply the flux on the joint and confirm that the pipe is inserted into the bottom of the socket， then wipe off the excess flux， and the joint is assembled and can be heated.
나는 없다;나는 동관을 어떻게 보존해야 할지 모르겠다.
타 폴 카물에 탄산수소칼슘， 육인산알코올， 인산규소 결정 등 부식제를 첨가해 물의 PH값과 부식 증상을 조절한다.
위생과 건강: 동관에 있는 플라스틱 관의 각종 변성제， 첨가제 및 기타 화학 성분.
화려 하 다.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，타 폴 카60SI2MN 합금 원강， so that dust and dirt will not pollute the capillary gap.
동관은 동관， 비철금속관이라고도 한다.그것은 일종의 압라무봉관으로 무게가 가볍고 열전도성이 좋으며 저온강도가 높고 부식에 견디는 등 특징을 갖고있다.동관은 이런 우수한 재산을 가지고 있기 때문에， 동관의 사용은 매우 보편적이다.경동관과 연동관은 사용 과정에서 어떤 차이가 있습니까?양자는 구체적인 응용 방면에서 어떤 차이가 있습니까?
If the corrosion on the copper surface is found to be slight， it can be erased with linen copper wire， but it is not recommended to apply oil for preservation.
동관 연결의 견고성이 강하다: 동관과 동관 부품의 연결이 견고하다.
높은 용접 온도의 작용으로 금속 아크 용접을 보호하는 과정에서 아연의 증발량은 % 에 달한다.대량의 아연 증발은 용접 헤드의 기계적 재산과 내식성을 떨어뜨리는 동시에 대응력 부식에 대한 민감성을 증가시킨다.
Generally oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.
전면 품질 관리월에 국내 중후판 가격이 대폭 하락했다.월 일까지 주요도시의 일반탄소판가격센터는 이미 으로 내려가 월말에 비해 톤당 원 하락했다.이달 초， 거시적인 나쁜 소식과 최근 기본면이 좋지 않은 영향으로 시장심리상태가 비관적으로 전환되였고 일부 거래원들은 저가로 출하했다.시장재고가 상승하고 재고압력이 높으며 재고부족현상이 소실되고 시장거래분위기가 랭담하며 수요표현이 지속적으로 하락하고 현물가격이 압력을 받아 하락하고있다.
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.
To sum up， due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants， the gradual emergence of supply and demand pressure， and the weakness of raw material support， among which the contraction of market demand has a greater impact. Therefore， the author believes that in the short term，타 폴 카스테인리스 강판，타 폴 카6082 알루미늄 바， the spot building materials do not have the possibility to rise significantly， and the price of building materials may mainly operate in shock， but with the shrinking demand the supply and demand pressure becomes prominent， However， considering the influence of winter storage and other factors， it is still possible for merchants to lower the spot price in November.
적동판은 연전성을 가지고 있다.순수한 구리는 물 한 방울만큼 커서 킬로미터 길이의 가는 실로 끌려가거나 침대보다 더 큰 투명박으로 말릴 수 있다.자동 배열의 가장 가치 있는 특성은 매우 좋은 전도성을 가지고 있으며， 그 다음이다일반 금속 중에서.그러나 구리는 은보다 훨씬 싸기 때문에 이미 & amp;quot；주인공 & amp;quot；전기 업계의 리더.
생산 하 다.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.
물의 PH 값이 미만이면 구리 벽에 산이 부식됩니다.
In the middle and late ten days， although there were good news such as the rise of futures and the increase of production restriction policy in Wuan region， due to the high inventory level， traders had no desire to increase prices， most of them had shipped goods， and spot prices lacked motivation to rise. The market inventory rose significantly. At that time， the market inventory in Handan reached a high level after the festival. The sluggish demand performance for a long time led to the oversupply of the market， and the continuous rise of inventory led to the empty market mentality.
타 폴 카The market opened today. Although the performance of Zitong Pai futures was modest， the overall market has stopped. The market mentality has not changed much sincekend. The price is stable， but some specifications are subject to negotiation， and the negotiation range is about - yuan. The overall rhythm of the market is stable and cold. In the middle of winter， and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature， the market was bleak.
Do not store too many other products， especially other acid materials and alkali materials， in the warehouse to prevent mutual reaction.
Five of the five major application fields of copper plate， copper bar and copper tube: copper is used in medicine. In the s， Chinese medical inventors Liu Tongqing and Liu Tongle found that copper has extremely strong s， and successfully developed the corresponding "Cancer Suppressing "， which is successful in the near future.
