용접할 때 드라이어는 납관에 수직해야 하고 화염은 련속 이동하여 국부적인 과열과 용접제가 충전금속을 첨가하기전에 탄화되는것을 방지해야 한다.
Save materials and total cost， stability and performance，곰 밑천316L 스테인리스 라운드 스틸， in September ， Chinas imported iron ore * * * broke through the million ton mark，곰 밑천310s 스테인리스 스틸 무봉관， reaching million tons， a record high; From January to September， Chinas iron ore import increased by % to million tons， and the annual import volume is expected to exceed billion tons. However， judging from the shipment of imported ores after the National Day， due to the rapid declinecline in iron ore prices， the iron ore price index once fell below $， which reduced the enthusiasm for the shipment of imported ores. In addition， environmental protection inspection has become stricter， the overall order receiving quantity of Tianjin Hebei Henan Plate Plant was not ideal. According to the monitoring data which is likely to decline further in the future.
나는 없다;나는 동관을 어떻게 보존해야 할지 모르겠다.
In the first ten days of May， the overall order intake of medium and heavy plate mills in Tianjin Hebei Henan region in the first ten days of May remained stable and weak. Due to the weak market shock， the overall order intake of the spot steel market was relatively weak. The total quantity of orders received in the first ten days of May is only about tons， while at the end of April， the total quantity of post settlement agreements of main steel plants can exceed tons.
배치할 때는 다른 성분에 따라 따로 보관해야 하며 함께 혼합해서는 안 된다.구리 표면에는 전해질이 있을 수 있기 때문에 반응할 수 있으며， 특히 고무 등 다른 재료와 반응할 수 있어 큰 영향을 미칠 수 있다.
It mainly refers to strengthening the research on copper pipe corrosion and formulating a complete and scientific copper pipe use plan.
동관의 전기 전도 생산은 이런 방법의 최신 방법이다.그것은 전도성을 가진 나노 결정 구리 재료의 생산이다.이 원재료는 매우 특수하기 때문에 나노기술을 이용하여 생산되는 구리 재료로 구리 이온은 전도성을 통해 분리될 수 있기 때문에 분리된 구리 이온으로 구리 파이프를 생산할 수 있다.이런 방법은 매우 복잡하고 첨단기술과 새로운 설비가 필요하기에 국외선진국만이 이런 생산방법을 사용할수 있다.
신용 과 신용 과 이익.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，곰 밑천스테인리스강 용접관， which is the development direction of copper tube industry in the future.
The 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， the overall market in Northeast China has entered the traditional off-season， and the overall market has ended with little improvement. All companies are selling goods. The inventory level in Shenyang is very low due to the inventory clearing， and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature， the market was bleak.
위생과 건강: 동관에 있는 플라스틱 관의 각종 변성제， 첨가제， 첨가제 및 기타 화학 성분.
antages: low production cost and high production efficiency.
설치 요구 사항파이프를 청소한 후에는 즉시 인터페이스와 카드 사이에 용접제와 보조용접제를 발라야 한다.배합면에 충분한 용접제를 얇게 바르고 먼지와 때가 모세관 간극을 오염시키지 않도록 즉시 조립해야 한다.
As the copper pipe is easy to process and connect it can save materials and total cost， stability and reliability， and can save maintenance during installation.
Four of the five major application fields of copper plate， copper bar and copper pipe: copper is used as various pipes， pipe fittings and decorative devices in the construction industry.
곰 밑천The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm， the elongation is ~%， and the Brinell hardness (HB) is ~
Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.
Lets elaborate on the advantages of copper pipe materials: copper pipe floor heating refers to a heating method that uses hot water as the thermal medium， heats the floor， and heats the floor through the ground in the form of radiation and convection heat transfer. I. The copper tube has fast heat dissipation effect and strong heat resistance. Even under the condition of high temperature water supply， the service life of the floor heating tube will not be affected. Two. Copper pipe is a metal pipe，o it is not easy to scratch. Therefore， it is not easy to leak. Three. High temperature resistance， high pressure resistance， relative to any ordinary plastic pipe. Copper tube floor is warm and resistant to high temperature and pressure. Four. Long service life. Five.
