首次焊管有關成型完整過程中，謄寫鋼版蛻變平均，較為留下（xià）剪應力小，要樣兒不（bú）形成燒傷（shāng）。進行加工的焊管在有關直徑和壁厚的度量衡規格適用範圍上有更大的更加靈活性，特別是在這種情況下在生產高（gāo）鋼級厚壁管，尤其是中飲啜徑厚壁管層（céng）麵具（jù）備其餘生產工藝束手無策比賽的主要優勢，可符合使用者在焊（hàn）管規格層麵數量更多的（de）具體要（yào）求;使用先預（yù）焊後裏裏外外焊(精焊)的生產工（gōng）藝，可在超等所在地達成銲接，著名發生錯邊、焊偏和未（wèi）焊透等進行裂縫。
Firstly, during the forming process of welded pipe, the steel plate has uniform deformation, small residual stress and no scratch on the surface. Processed welded pipes have greater flexibility in the size and specification range of diameter and wall thickness, especially in the production of high-grade thick-walled steel pipes, especially medium and small-sized thick-walled pipes, which have incomparable advantages compared with other processes, and can meet more requirements of users in the specification of welded pipes. The process of pre-welding before internal and external welding (fine welding) can be used to achieve welding in the best position, and it is not easy to appear staggered edges. Defects such as welding deviation and impermeability. 在（zài）滿足相關（guān）條件（jiàn）時開展（zhǎn）從整體上看（kàn）機（jī）械擴徑，可切實有效地使原有（yǒu）水平上升（shēng）焊管的度量衡精確（què）程度，並改進焊管（guǎn）內剪應力的（de）進（jìn）行散步情（qíng）況，進而（ér）防止因為剪應力（lì）破壞導致的風吹雨打（dǎ），與此同時較為有益於（yú）工作現場的（de）銲接開展施工（gōng）;對焊管開（kāi）展9項100%的質量進行檢查，使焊管生產的全完整過程均在切實有效的開展檢測（cè）、實時監督以下，切實（shí）有效執政官證了（le）產質量水平量。
If the overall mechanical diameter enlargement is carried out, the dimensional accuracy of welded pipe can be effectively improved, and the stress distribution in welded pipe can be improved, so as to avoid the damage caused by stress corrosion, and at the same time, it is conducive to the field welding construction; 9 100% quality inspections are carried out on welded pipe, so that the whole process of production of welded pipe is effectively inspected and monitored, and the product quality is effectively guaranteed.
焊建工藝（yì）操作流（liú）程（chéng）：原材料認為――平坦――端部（bù）劃分及銲接――繩套（tào）――變化――銲接――裏裏外（wài）外焊珠引起――預標（biāo）定――影響熱采用相（xiàng）應（yīng）辦法解決――定徑及校（xiào）直――傅科電流開展檢測――隔離――水壓（yā）進行檢查――酸洗――到（dào）最後進行檢查(從（cóng）嚴審定)――產品包裝――進行恢複。
Welded pipe process: raw material uncoiling - leveling - end shearing and welding - looper - forming - Welding - internal and external bead removal - pre-correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - water pressure inspection - acid washing - final inspection (strict control) - Packaging - delivery.
焊管普遍應用於從來水利工程程、石油化（huà）工工（gōng）業領域、化毖勞業、核動力工業領域、農業澆灌（guàn）、城市開展（zhǎn）建設，是本國研發的（de）關於二十個核心要點產品某個。
Welded pipe is widely used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, and is one of the 20 key products developed in China.
