동관 연결의 견고성이 강하다: 동관과 동관 부품의 연결이 견고하다.
The simplest way is to use copper cleaner. Brass， red copper， bronze， etc. can be used. Oil stains， fingerprints， oxide layers， the sheet metal shall be first opened in the sheet metal workshop according to the dimensions shown in the drawings， which is commonly referred to as opening. Then cut the corners of these open sheets according to the height of the edge，크 록 스 토 퍼H65 황동판， and then use the bending machine to form the edge according to the drawing forming diagram. The shaped copper pipe shall also be installed with reinforcing ribs as required， and the four corners of the shaped plate shall be welded well. The welded parts shall be sent to the grinding workshop， and the spraying surface shall be polished and the welding interface shall be polished and leveled. The polished modeling copper pipe is then sent to the spraying workshop for processing. Before spraying the surface of the sculpted copper pipe shall be chrome treated and the process hole shall be drilled， so as to ensure that the sculpted copper pipe can be hung on the spraying line well， and the painting can be smooth without flow marks， and the color is consistent without color difference. After that， according to customer demand， the qualified products are pasted with protective film and bound with bubble film or wooden box.
Copper tube is a kind of nonferrous metal tube， which is pressed and drawn seamless tube. The copper pipe has good thermal conductivity， and is solid and corrosion resistant. It will not crack when compared with the ambient temperature， so it becomes the first choice for modern contractors to install the water pipe， heat supply pipe and refrigeration pipe in all residential commercial houses.

동관은 수도관， 난방관， 냉동관을 설치하는 것이 가장 좋은 특징을 가지고 있다.
Advantages: good quality， fine structure， high density， high pressure resistance， suitable for frequent cold and heat exchange， large temperature difference in working environment，크 록 스 토 퍼스테인리스강 용접관， and large size copper tube can be produced.
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， the filler metal shall melt.
The water quality at the place where the copper pipe is required to be installed shall be studied， and the appropriate water quality and water flow shall be selected for pipe distribution to prevent the root cause.
The material of the water separator is the same， the expansion coefficient is the same， and the connection with the water separator is not easy to leak. Scope of application: As the copper pipe is more expensive than the plastic pipe， the cost of the floor heating system is higher.

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.
In view of the current overall price difference， the local copper bar price continued to rise at a high level today， while the regions outside East China did not show an obvious follow-up trend， and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction， and the price support of copper bar is still strong. However， at present， domestic real estate control is still being tightened. The markets expectation of future demand is weakening， and the markets fear of heights appears after the price rises.Today， the market price of copper bars in Shenyang is stable and the shipment is poor.
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， heating and cooling pipes in all residential commercial housing.
손님 을 존경 하 다.Red copper plate has ductility. Pure copper， which is as big as a drop of water， can be pulled up to two kilometers of thin wire or rolled into a transparent foil larger than a bed. The most valuable property of red copper row is that it has a very good conductive ， second onlyver in common metals. But copper is much cheaper than silver so it has become the "protagonist" of the electrical industry.

In 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， 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， B yuan/ton; Jiujiang # - # to Tianjin yuan/ton; The arrival price of Xinji Aosen # is yuan/ton， B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton， B steel yuan/ton.
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.
