style="text-indent:25px">不銹鋼無縫管按GB14975-94《不銹鋼無縫鋼管》規(guī)定，鋼管通常長度(不定尺)熱軋鋼管1.5～10m，熱擠壓鋼管等于和大于1m。冷拔(軋)鋼管壁厚0.5～1.0mm者，1.0～7m；壁厚大于1.0mm者，1.5～8m。熱軋(熱擠壓)鋼管的直徑54～480mm共45種；壁厚4.5～45mm共36種。冷拔(軋)鋼管的直徑6～200mm共65種；壁厚0.5～21mm共39種。鋼管內(nèi)外表面不得有裂縫、折疊、龜裂、裂紋、軋折、離層和結(jié)疤缺陷存在，這些缺陷應(yīng)完全去除掉(供機(jī)械加工用管除外)，去除后不得使壁厚和外徑超過負(fù)偏差。凡不超過允許負(fù)偏差的其他輕微表面缺陷可不去除。直道允許深度。熱軋、熱擠壓鋼管、直徑小于和等于140mm的不大于公稱壁厚的5%，較大深度不大于0.5mm；冷拔(軋)鋼管不大于公稱壁厚的4%，較大深度不大于0.3mm。不銹鋼無縫管，英文名稱為Stainless
