用旋轧焊坯制造不锈钢薄壁钢管,生产工艺简单,钢管表面光洁,尺寸精确,机械性能及耐腐蚀性能好,综合性能优于无缝薄壁钢管和焊接薄壁管,是制造波纹管较理想的材料.焊坯旋轧制管工艺包括毛坯管的焊接、热处理、酸洗、旋轧和成品薄壁管的热处理等工序.薄壁管表面光洁度达▽6以上,壁厚偏差为0.02—0.09毫米,焊缝处的性能较高而均匀,抗腐蚀性能良好。爆破压力比焊接薄壁管高18.2%.比无缝管高15.3%。
The manufacture of stainless steel thin-wall steel pipe by using the rolling welding blank has the advantages of simple production process, smooth steel pipe surface, precise size, good mechanical property and corrosion resistance, better overall performance than seamless thin-walled steel pipe and welded thin-walled pipe, The ideal material.Welding pipe rolling pipe process including rough tube welding, heat treatment, pickling, rolling and thin tube heat treatment process.Micro-thin tube surface finish of ▽ 6 or more, the thickness deviation of 0.02- 0.09 mm, the performance of the weld at high and uniform, good corrosion resistance. Burst pressure is 18.2% higher than welded thin-walled tubes and 15.3% higher than seamless tubes.
