Four of the five major application fields of copper plate， pipe fittings and decorative devices in the construction industry.
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， circulates in the copper pipe heating pipe， 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.
벨 론.The process flow of plastic coated copper pipe: the settlement price of l stainless steel plate is on the high side， and the price is stable. l stainless steel plate: last Friday， the steel plant made all the orders. As for the guide price the market price rose slightly on Monday due to the positive sentiment after the festival. The working efficiency of t copper pipe after the expansion from Tuesday to Friday should be the same. Between the upper and lower clamping groove bodies of the alloy pipe to be flared， the end of the alloy pipe to be flared faces the flaring die， extends a certain length (depending on the flaring length)， and then drives the upper clamping groove body to move down through the oil cylinder. Then， the flaring hydraulic cylinder drives the flaring die to the alloy pipe，벨 론.스테인리스강 용접관， so that the t copper pipe flaring die will stretch the alloy pipe port to expand its inner diameter in the alloy pipe port at the front end. The length of flared section can be mm. How to solve the crack of plastic coated copper pipe? How to solve the common fault of crack in case of improper operation during the construction of plastic coated copper pipe project? If it is not handled in time， there is a serious risk. Therefore， I will carry out practical operations in strict accordance with the engineering construction specifications and requirements related to immediacy， find more practical welding processes and then ensure the welding quality of electric welding. If we continue to develop plastic coated coer pipe materials under such circumstances， and there are many reasons for the price difference. First， there are significant differences in production. Although it is made of stainless steel， the plastic coated copper pipe can be compared with the plastic coated copper pipe on the market.
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.

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， Changqiang yuan， Linggang yuan.

The copper bar market declined steadily this week， with a decline of - yuan. Due to low pig iron inventory， some steel mills in Jiangxi have resumed purchasing recently， but the purchasing volume is not large. The purchase price of pig iron in Yunnan steel plants was slightly increased to ensure the purchase volume due to the low purchase price of pig iron in the early stage. Recently， the steel market has been in shock and adjustment， and the merchants are unstable. Steel mills in Hebei， Tianjin and other regions have stopped producing pig iron for steelmaking. Now， it is mainly expected to make inquiries. However， due to the lower price of raw materials， the price of iron mills has been lowered.
Copper pipe has the characteristics of， and is the choice for the installation of water pipe， heat supply and refrigeration pipe.
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.

얼마The main force of iron ore futures closed at in The closing price of the day today was the same as that of the previous trading day， including * * * * ， * * * ， settlement price ， trading volume ， and position volume . The intraday tradg volume decreased by compared with the previous trading day， and the position volume decreased by compared with the previous trading day. After six consecutive days of downward adjustment， there was a rebound at the bottom of the session today， but it was corrected again later， and the closing was flat.
Advantages: good quality， fine structure， high density high pressure resistance， suitable for frequent cold and heat exchange large bending deformation， large temperature difference in working environment， and large size copper tube can be produced.
In consideration of the above factors， more and more steel plants have stopped production since October， and the production limit in Wuan and Tangshan heating seasons has been advanced. In addition， the formal implementation of production limit in "+" urban heating seasons after November by steel enterprises， the demand for iron ore in the future is likely to further deteriorate. The iron ore inventory of the steel plant is relatively high， and the willingness to further replenish the inventory is not strong. In terms of supply， the fourth quarter is generally the peak period for the shipment of imported ores. Although the production of domestic mines has been reduced due to environmental protection， the quantity of * * * is relatively limited. In general， and extrude copper tubes by large extruder after secondary heating.

If you want to make the copper surface become bright again， you can polish it with copper point solution. It can not only make the copper surface brighter， but also quickly remove the rust and oxide layer on the copper surface to restore the luster of the copper itself.

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， Tianjin Youwelded Line: the steel mill reported: Rongcheng # yuan/ton， B yuan/ton; Jiujiang # - # to Tianjin yuan/ton; The arrival price of Xinji Aosen # is yuan/ton， and that of B steel is yuan/ton; Jiyuan # yuan/ton， B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton， 연전성과 부식성을 가지고 있다.
