Do not store too many other products， especially other acid materials and alkali materials， in the warehouse to prevent mutual reaction.
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.
앉 고 맑 은 하늘.축축한 공기 중의 구리의 부식은 일종의 화학 반응으로， 그것은 coppe를보기 싫다.이상의 조작은 동관을 더욱 아름답게 할 것이다.밝은 동관은 오늘날에도 여전히 흔하다;그것의 일상생활은 많은 곳에서 사용될 것이다.그러나 이러한 일반적인 제품에도 불구하고 많은 사람들이 성능 특성을 이해하지 못하고 있습니다.그렇다면 이 제품의 뛰어난 성능 특징은 무엇입니까?여기는 본문의 간략한 소개입니다.
On November ， the market price of Cangzhou copper bar was stable. According to the monitoring data of Lange Iron and Steels cloud business platform， the market price of * mm cold drawn steel produced in Linyi is yuan， the market price of * mm in Linyi is yuan， the market price of * mm in Jianlong is yuan， the market price of * mm in Yuanhua is yuan， the market price of * mm in Juneng is yuan， the market price of * mm in Baotou Steel is yuan， and the market price of * mm in Juneng thermal expansion is yuan.
세 인 트 마리 아The application of copper tube The copper tube is generally used in the heat exchange equipment， and the low-temperature pipeline in the oxygen production equipment can also be used. Some relatively thin copper tubes can be used to transport some pressurized liquids， and can also be used as pressure measuring tubes in instruments; In addition the copper pipe is relatively firm， unlike other metals，앉 고 맑 은 하늘.6061 알루미늄 바， which are easily corroded， so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.
Later， Mexican scientists also found that copper has a . Recently， British researchers found that copper has a strong bactericidal effect. It is believed that in the near future， copper will make great contributions to improving human health. Copper plate T is named after its purple color. It is not necessarily pure copper， sometimes it also involves a few deoxidizing elements or other elements to improve raw materials and s， so it is also included in copper alloys. The processed materials of Chinese cor plate can be divided into four categories according to the composition: ordinary copper plate (T， T， T， T， oxygen free copper plate (TU， TU and high-purity， vacuum oxygen free copper)， deoxidized copper plate (TUP， TUMn)， and special copper plate (arsenic copper， tellurium copper， silver copper) with a few alloy elements added. The conductivity and thermal conductivity of copper plate are second only to silver， and are widely used to manufacture conductive and thermal conductive devices. The red copper belt has outstanding corrosion resistance in the atmosphere， sea water， some non oxidizing acids， alkalis， salt solutions and a variety of organic acids (aic acid， citric acid)， and is used in the chemical industry. In addition the red copper plate has outstanding weldability and can be made into various semi products and products through cold and thermoplastic processing. In the s，앉 고 맑 은 하늘.316L 스테인리스 스틸 롤러， copper bar and copper pipe: copper is used as various pipes， pipe fittings and decorative devices in the construction industry.

Advantages: good quality， fine structure， high density， high pressure resistance， large bending deformation， suitable for frequent cold and heat exchange， large temperature difference in working environment， and large size copper tube can be produced.
안전 요구Three of the five major application fields of copper plate， copper bar and copper tube: copper is used to manufacture， and gun parts in the national defense industry. Every million rounds of copper are produced， - tons of copper are needed.
구리 재료의 저장 방법에 대해 말하자면， 구리의 사용 수명을 연장하며， 그 성능을 확보하여 불필요한 손실을 피해야 한다.
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.

In view of the current overall price difference， 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， the market price of copper bars in Shenyang is stable and the shipment is poor.
