環(huán)球新聞資訊，9月6日獲悉：【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】加強級tpep防腐鋼管經(jīng)測定，管子內(nèi)壁表面的粗糙度所起的影響要比局部隆起的面積(如螺旋形的焊縫或縱長的焊縫、甚至包括內(nèi)環(huán)形焊縫)所起的影響大十倍。生產(chǎn)與管理螺旋焊縫鋼管的生產(chǎn)能體現(xiàn)出優(yōu)質(zhì)高效的優(yōu)勢。一臺螺旋焊管機組的生產(chǎn)量相當于5-8臺直縫焊管設(shè)備，如何使多臺卷管設(shè)備生產(chǎn)線都能夠達到同一制作標準，即按統(tǒng)一的生產(chǎn)工藝規(guī)范和質(zhì)量保證體系生產(chǎn)以滿足焊接質(zhì)量要求與管道制造等級將是一項繁重的工作。多頭生產(chǎn)勢比增加工程管理與質(zhì)量監(jiān)督的工程量。多臺直縫卷管機組及相應(yīng)的焊接設(shè)備，其操作人員的操作技能、【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】質(zhì)量意識、分布的點和控制程序的差異將帶來生產(chǎn)管理、計劃進度、檢查驗收、交付協(xié)調(diào)等方面的諸多困難，極易造成管理與協(xié)調(diào)上的忙亂和生產(chǎn)廠家與施工單位的質(zhì)量推諉。【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】 往往是在現(xiàn)場能夠達標，經(jīng)過搬運、敲打后， 磁場又超標了。其原因就是大口徑螺旋鋼管如何退磁內(nèi)部的磁疇沒有經(jīng)過"磁鍛煉"處于不很穩(wěn)定狀態(tài)。大口徑螺旋鋼管如何退磁剩磁的標準是30GS以下，HT30D鋼管退磁系統(tǒng)能夠?qū)摴苁４欧(wěn)定退到10GS左右，【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】以避 免在以后的運輸過程中剩磁再反彈。 熔渣浮在金屬熔池的表面，一方面可以保護焊縫金屬，防止空氣的污染，并與熔化金屬產(chǎn)生物理化學反應(yīng)，改善焊縫金屬的萬分及性能；另一方面還可以使焊縫金屬緩慢泠卻。

Global News, September 6, learned: [Senior Manager of Shengkuang Pipe Industry 13730570531 QQ: 2927372564] Strengthened grade TPEP anticorrosive steel pipes were tested. The roughness of the inner surface of the pipes affected more than the area of local bulge (such as spiral welds or longitudinal welds, even including inner ring welds). Double. Production and manag【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】ement of spiral welded pipe production can reflect the advantages of high quality and high efficiency. The production capacity of a spiral welded pipe mill is equal to 5-8 vertical welded pipe equipments. It will be a heavy task to make the production lines of several coiled pipe equipments reach the same production standard, that is, according to the unified production process specification and quality assurance system to meet the welding quality requirements and pipe manufacturing grade. The production capacity of multi head is higher than that of engineering management and quality supervision. The difference of operation s【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】kills, quality awareness, distribution points and control procedures among the operators of several straight-seam pipe rolling units and corresponding welding equipment will bring about many difficulties in production management, schedule, inspection and acceptance, delivery and coordination, which will easily lead to confusion in management and coordination and confusion among manufacturers and construction units. The quality 【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】of buck passing. It often reaches the standard at the scene. After handling and knocking, the magnetic field is over standard. The reason is that the magnetic domain inside the large diameter spiral steel tube is not very stable without magnetic training. The standard of how to demagnetize the large diameter spiral steel pipe is below 30GS. The demagnetization system of HT30D steel pipe can stabilize the remanence of the steel pipe to about 10GS, so as to avoid the remanence rebound during the later transportation. Slag floating on the surface of the metal pool, on the one hand, can protect the weld metal, prevent air pollution, and produce physical and chemical reactions with the molten metal, improve the weld metal and properties; on the other hand, can also make the weld metal cooling slowly.【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】
 On the basis of fully utilizing the reserved facilities of the No.1 and No.2 blast furnaces system of Zhanjiang Iron and Steel Company, this project extends the equipments of raw material wharf, raw material yard, sintering machine, coke oven, blast furnace and converter to produce low cost and high quality billets. _This project has a new hot rolling unit with ultra-high strength steel production capacity and one cold rolling unit each, in which cold rolling unit combined with the production line adjustment in Shanghai area, considering the relocation of part of the Shanghai stainless steel cold rolling line. This project adds 4.02 million tons of molten iron, 3.6 million tons of molten steel, 4.5 million tons of hot-rolled products and 1.66 million tons of cold-rolled products annually.【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】 After the completion of the project, the total scale of Zhanjiang iron and steel is 12.25 million tons of molten iron, 12.528 million tons of molten steel and 10.81 million tons of steel. According to the preliminary forecast, the total investment of the project is 18.85 billion yuan, and the financial internal rate of return is about 11.9% according to the actual production performance of Zhanjiang Iron and Steel in the past three years.  |
