연동관의 생산 방법은 경동관과 기본적으로 같다. 즉 경동관에 비해 퇴화 공정을 증가시켰다.동관의 퇴화는 그들이 고온로에서 하소하여 동관의 원소의 배열을 바꾼다는 것을 의미한다.그러나 불이 꺼지면 구리 파이프가 부드러워져 더 쉽게 구부러집니다.이런 방식으로 생산된 동관을 소프트 동관이라고 한다.

In August， the price of domestic medium and heavy plates fell sharply. As of August ， down yuan/ton from the end of July. At the beginning of the month， affected by the macro bad news， and the recent poor performance of fundamentals， the market mentality turned to pessimism， and some traders shipped at low prices. The market inventory rose， the inventory pressure was high， the stock shortage phenomenon disappeared， and the market transaction atmosphere was cold， the demand performance continued to decline， and the spot price fell under pressure.
However， it may cause recoverable temporary damage to people who have been away from these radioactive sources for a long time. The DC brushless motor with small volume and large power is adopted， which can operate without fault for a long time even if it is opened or closed. Target There will be no sharp decline in the price of copper tubes in Linyi at the end of the month. The price of plastic coated copper pipe will continue. Pop up the position line and line， select PVD chromium nitride ring and molybdenum spraying ring as the matching materials for the plastic coated copper pipe， adhere to the wear form condition simulation criteria of the sample test， use the self-developed opposed reciprocating wear tester， carry out the load level test， wear test， lean oil test， and research the load. As for the corrugated process of the finished plastic coated copper pipe as claimed in claim ，간디 아합금 강판， the radiation source for the engineering design of the integrated rigid flexible connection plastic coated copper pipe belongs to the low hazard source. Basically， it will not cause artificial damage. The basic principle of the foundation of the integral rigid flexible connection plastic coated copper pipe sluice discussed the influence of process parameters and heat treatment process on the microstructure， phase distribution and mechanical properties of the alloy， and obtained some important research results. The number of joints of steel pipes and plastic coated copper pipes on the same section shall not exceed % of the number of pipes. Before installation， the pipe shed ssweep and clean the hole with drill bit or high-pressure air， and the scum in the hole shall be removed， Ensure the aperture (The hole diameter shall not be less than cm， the deformation resistance is relatively small， and generally the steel plate is used for rolling. In this operation， the detailed thickness of the steel plate shall also be considered. If it is about the harmful elements with relatively low accuracy requirements， plastic coated copper pipes must be required. The pipe shed can be installed， extended section by section， and What does plastic coated copper pipe with a diameter of reflect in life when the weld length is added to for the joint steel pipe of the pipe extension joint? Plastic coated copper pipe can also produce welded pipes with different pipe diameters from billets of the same width. However it can be compared with straight seam pipes of the same length. The rental production rate is low.
It can be wrapped with moisture-proof paper for moisture-proof protection. It can also prevent oxidation to a certain extent. If cracks or serious corrosion are found， they must be isolated.
재산권.Today the price of tube billets is up and down. At present， Jiangxin hot rolling is yuan， continuous casting yuan is down yuan， Dongfang hot rolling yuan is down yuan， Luli hot rolling yuan is down yuan， Tiangang hot rolling an is down yuan， production is stopped in mid January， Weigang hot rolling yuan is up yuan， continuous casting yuan is up yuan， Huaigang yuan is up yuan， Zhongtian yuan， Changqiang yuan， Linggang yuan.
동관의 단점은 동관의 경우 높은 생산 원가와 높은 가격이 가장 큰 단점이다.다른 파이프 부품에 비해 구리 파이프의 원가가 훨씬 높고 구리 파이프 인터페이스의 연결은 비교적 높은 시공 기술 수준을 요구한다.
For small diameter pipes， when using filler metal the length of filler metal is allowed to be equal to the diameter of the pipe， which is enough to fill the weld crater. One of the five major application fields of red coppr plate T， red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries， accounting for more than half of the total consumption. Used for various cables and wires， motors and transformers， switches and printed circuit boards; In the manufacture of machinery and transport vehicles， instruments， sliding bearings， molds， heat exchangers，간디 아붉은 동관， pumps， etc.
Disadvantages of copper pipe As far as copper pipe is concerned， high production cost and high price are its biggest disadvantages. Compared with other pipe fittings， the cost of copper pipe is much higher， and the connection at the copper pipe interface requires high construction technology level.
환경 을 검증 하 다Among the three production methods of copper tube the oxidation method is the most. Because as long as the metal copper is oxidized by the anode and the copper ion of the anode is attached to the tube material， the copper tube can be produced. Thisthod is also the most common method to produce copper materials. It has not only been used for a long time， but also has a mature technology， which is to produce copper tubes through oxidation reaction. This production method is the main production method of copper tubes in China.
동관 용접 정밀도가 높고 생산 속도가 빠르며 표면의 광결도가 좋고 외형이 아름답다.따라서 유리， 철물， 전자， 부품， 목욕 및 주방 기구와 같은 정밀 용접 산업에 널리 사용됩니다.
경동관은 신축이나 압출 후 인공 처리를 거치지 않아 자연적으로 형성될 수 있다.이제 구리 파이프의 조직 형태가 가득 찼습니다.이런 동관은 갈라지기 쉬워서 구부리기에 적합하지 않다.그러므로 경동관은 일반적으로 곧다.
간디 아오늘 오전 개장할 때 정주 동배시장의 가격은 기본적으로 안정되였다.랭거윈상무플랫폼의 감시측정수치에 따르면 * mm 림기동봉의 현재 시장가격은 원 (톤가격， 이하 같음) 이고 * mm 동봉은 원이며 * mm 동봉 하남동봉은 원이다.
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.
At present， the fundamentals faced by the domestic copper bar market are still mixed. On the one hand， the market supply is expected to shrink， but on the other hand， the northern market has entered the off-season of demand， and the markets expectation of future demand is pessimistic. In the short term， domestic steel prices will enter the operating track of range consolidation. To sum up， considering the current situation of demand and inventory in the steel market， it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching， environmental protection phenomena such as steel mills are still going on and black series speculation is still taking place. But personally， the fluuation range of the market in this region is limited， and the shipment transaction is * * *.
