加強級tpep防腐鋼管

環球新聞資訊，9月6日獲悉：【勝倉管業 高經理13730570531  QQ：2927372564】加強級tpep防腐鋼管經測定，管子內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、甚至包括內環形焊縫)所起的影響大十倍。生產與管理螺旋焊縫鋼管的生產能體現出優質高效的優勢。一臺螺旋焊管機組的生產量相當于5-8臺直縫焊管設備，如何使多臺卷管設備生產線都能夠達到同一制作標準，即按統一的生產工藝規范和質量保證體系生產以滿足焊接質量要求與管道制造等級將是一項繁重的工作。多頭生產勢比增加工程管理與質量監督的工程量。多臺直縫卷管機組及相應的焊接設備，其操作人員的操作技能、【勝倉管業 高經理13730570531  QQ：2927372564】質量意識、分布的點和控制程序的差異將帶來生產管理、計劃進度、檢查驗收、交付協調等方面的諸多困難，極易造成管理與協調上的忙亂和生產廠家與施工單位的質量推諉。【勝倉管業 高經理13730570531  QQ：2927372564】  往往是在現場能夠達標，經過搬運、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部的磁疇沒有經過"磁鍛煉"處于不很穩定狀態。大口徑螺旋鋼管如何退磁剩磁的標準是30GS以下，HT30D鋼管退磁系統能夠將鋼管剩磁穩定退到10GS左右，【勝倉管業 高經理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，并與熔化金屬產生物理化學反應，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。

寶鋼擬投近190億建設湛江鋼鐵三高爐系統項目【勝倉管業 高經理13730570531  QQ：2927372564】
 寶鋼股份28日發布的公告顯示，公司擬建設寶鋼湛江鋼鐵三高爐系統項目。
  據了解，湛江鋼鐵基地一、二高爐系統建成后，充分發揮出運營成本、生產技術水平、勞動效率等多方面優勢，快速實現盈利，體現出極強的綜合競爭力。為進一步鞏固和強化寶山鋼鐵股份有限公司(以下簡稱“公司”)在優質碳鋼扁平材領域的領先地位，提升公司業績，擬建設寶鋼湛江鋼鐵三高爐系統項目(以下簡稱“本項目”)。
  本項目在充分利用湛江鋼鐵一、二高爐系統預留設施基礎之上，適當擴建原料碼頭、原料場、燒結機、焦爐、高爐、轉爐等裝備，生產低成本、高品質的鋼坯。【勝倉管業 高經理13730570531  QQ：2927372564】
  本項目新建具備超高強鋼生產能力的熱軋單元和冷軋單元各1個;其中冷軋單元結合上海地區的產線調整，考慮搬遷部分上海不銹的冷軋產線。本項目年新增鐵水402萬噸、鋼水360萬噸、熱軋產品450萬噸、冷軋產品166萬噸。
  項目建成后湛江鋼鐵總規模為年產鐵水1,225萬噸、鋼水1,252.8萬噸、鋼材1,081萬噸。經初步預測，項目總投資188.5億元;參照湛江鋼鐵近三年生產實績測算的財務內部收益率約為11.9%。

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 高經理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 高經理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 高經理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 高經理13730570531  QQ：2927372564】
