首先焊管成型过程中，钢板变形均匀，残余应力小，表面不产生划伤。加工的焊管在直径和壁厚的尺寸规格范围上有更大的灵活性，尤其在生产高钢级厚壁管，特别是中小口径厚壁管方面具有其他工艺无法比拟的优势，可满足用户在焊管规格方面更多的要求;采用先预焊后内外焊(精焊)的工艺，可在最佳位置实现焊接，不易出现错边、焊偏和未焊透等缺陷。
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. 如果进行整体机械扩径，可有效地提高焊管的尺寸精度，并改善焊管内应力的分布状态，从而避免由于应力腐蚀造成的破坏，同时有利于现场的焊接施工;对焊管进行9项100%的质量检查，使焊管生产的全过程均在有效的检测、监控之下，有效地保证了产品质量。
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.
焊管工艺流程：原材料开卷――平整――端部剪切及焊接――活套――成形――焊接――内外焊珠去除――预校正――感应热处理――定径及校直――涡流检测――切断――水压检查――酸洗――最终检查(严格把关)――包装――出货。
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.
焊管广泛应用于自来水工程、石化工业、化学工业、电力工业、农业灌溉、城市建设，是我国开发的二十个重点产品之一。
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.
