冷拔無縫鋼管彎管時候出現斷裂怎麼解決？

今天冷拔無縫鋼管廠傢來說說冷拔無縫鋼管彎透水地坪管時候出現斷裂怎麼解決：最近有個老客戶和我詢價時候順便向我請教彎管的問題。他反應在別傢買瞭一批冷拔無縫鋼管拿回去做90度彎管時出現斷裂情況，問我們傢的管子做彎管會不會出現這種情況。
Today, the cold-drawn seamless steel pipe manufacturer talks about how to solve the problem of cracking when cold-drawn seamless steel pipe bending occurs: Recently, an old customer and I asked me for advice when inquiring about the problem of pipe bending. He responded that a group of cold-drawn seamless steel pipes were broken when they were taken back to make 90-degree bends, and asked if this would happen when our pipes were made bends. 我當時就想要麼是客戶彎管時操作方法不當要麼就是冷拔無縫鋼管出現瞭問題。我把他彎斷的管子拿瞭兩段到我們公司化驗檢測。發現幾個問題：第一，管子的硬度太高，含錳元素和碳元素過高，導致管子脆性較高。第二:冷拔無縫鋼管的焊縫是在外面的，第三：冷拔無縫鋼管的拉伸性較低。這下原因找到瞭問題就出現在冷拔無縫鋼管上面。後來我電話聯系客戶說瞭原因然後提瞭幾點解決方法：第一：買冷拔無縫鋼管時要符合國傢標準的304冷拔冷拔無縫鋼管，第二：買貨時候要說明是做彎管用的供應商就會註意；要求冷拔鋼管在管子內表面這樣導致彎管斷裂的情況會降低，第三：冷拔無縫鋼管的拉伸性能要高，滿足對拉伸、彎曲等加工的嚴格要求,第四：冷拔無縫鋼管加工彎管的話建議最好買冷拔工藝的，冷軋冷拔無縫鋼管加工彎管危險性比較高，第五：彎管加工時候冷彎出現斷裂時候我麼可以改成熱彎加工工藝。
At that time, I wanted to either the customer bending the pipe improperly or cold-drawn seamless steel pipe problems. I took two sections of his broken pipe to our company for testing. Several problems have been found. First, the high hardness of the pipe and the high content of manganese and carbon lead to the high brittleness of the pipe. Seco环氧地坪nd, the weld of cold-drawn seamless steel pipe is outside. Third, the tensile strength of cold-drawn seamless steel pipe is low. The problem was found on the cold-drawn seamless steel tube. Later, I contacted customers by telephone to explain the reasons and put forward several solutions: first, when buying cold-drawn seamless steel tubes, 304 cold-drawn seamless steel tubes that meet the national standards should be met; second, when purchasing goods, the suppliers who are making bends should pay attention to it; requiring welded pipes to break on the inner surface of the tubes will reduce; third, the tensile properties of cold-drawn seamless steel tubes should be improved. Fourth, cold-drawn seamless steel pipe bending process is recommended to buy cold-drawn process, cold-rolled seamless pipe bending process is more dangerous. Fifth, when cold-formed pipe breaks, we can change to hot-bending process.
