　　鋼板卷管也稱鋼板卷管，卷板加工是用鋼板或帶鋼經由曲折成型后焊接制成的鋼管。鋼板卷管出產技術簡略，出產功率高，品種標準多，設備資少，但一般強度低于無縫鋼管。,熱卷厚壁卷管的壁厚一般超過20mm，外徑范圍450-3000mm，熱卷厚壁卷管是(shi)在(zai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)加(jia)(jia)熱(re)的(de)(de)(de)狀態下(xia)卷(juan)(juan)(juan)(juan)制、焊(han)(han)接、成(cheng)型、去筋、探傷、出廠。有時(shi)壁厚(hou)較為特殊(shu)厚(hou)的(de)(de)(de)還需(xu)要二次加(jia)(jia)熱(re)。特點(dian)在(zai)于(yu)外徑(jing)公差小、壁厚(hou)均勻等(deng)(deng)，主(zhu)要的(de)(de)(de)是(shi)熱(re)卷(juan)(juan)(juan)(juan)厚(hou)壁卷(juan)(juan)(juan)(juan)管(guan)(guan)(guan)不會傷害到(dao)原材料的(de)(de)(de)性能，熱(re)卷(juan)(juan)(juan)(juan)厚(hou)壁卷(juan)(juan)(juan)(juan)管(guan)(guan)(guan)的(de)(de)(de)弊端是(shi)加(jia)(jia)工時(shi)間(jian)較長、造(zao)價高。熱(re)卷(juan)(juan)(juan)(juan)厚(hou)壁卷(juan)(juan)(juan)(juan)管(guan)(guan)(guan)被(bei)廣泛用到(dao)：油缸、液壓、橋梁(liang)、輥筒等(deng)(deng)。,卷(juan)(juan)(juan)(juan)管(guan)(guan)(guan)加(jia)(jia)工選用的(de)(de)(de)坯料是(shi)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)或帶鋼(gang)(gang)(gang)，卷(juan)(juan)(juan)(juan)板(ban)(ban)(ban)(ban)加(jia)(jia)工因其焊(han)(han)接技術不合而分(fen)為爐鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)卷(juan)(juan)(juan)(juan)管(guan)(guan)(guan)、電焊(han)(han)(電阻焊(han)(han))管(guan)(guan)(guan)和主(zhu)動電弧鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)卷(juan)(juan)(juan)(juan)管(guan)(guan)(guan)。因其焊(han)(han)接辦法的(de)(de)(de)不合分(fen)為直縫(feng)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)卷(juan)(juan)(juan)(juan)管(guan)(guan)(guan)和螺旋鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)卷(juan)(juan)(juan)(juan)管(guan)(guan)(guan)兩種。因其端部外形又分(fen)為圓形鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)卷(juan)(juan)(juan)(juan)管(guan)(guan)(guan)和異型(方、扁等(deng)(deng))鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)卷(juan)(juan)(juan)(juan)管(guan)(guan)(guan)。

　　鋼板卷管的(de)優勢(shi)和作用

　　鋼(gang)(gang)板(ban)卷(juan)(juan)管(guan)(guan)相(xiang)(xiang)對(dui)于大口徑(jing)鋼(gang)(gang)管(guan)(guan)來說，具有造價低廉(lian)、起訂量小(xiao)、交貨快等(deng)特點。鋼(gang)(gang)板(ban)卷(juan)(juan)管(guan)(guan)在鋼(gang)(gang)板(ban)的基礎(chu)上(shang)添加(jia)加(jia)工費用即可(ke)，且鋼(gang)(gang)板(ban)卷(juan)(juan)管(guan)(guan)用的原(yuan)料鋼(gang)(gang)板(ban)可(ke)以說普遍的很，所以并不由市場的缺陷。而相(xiang)(xiang)對(dui)于大口徑(jing)鋼(gang)(gang)管(guan)(guan)就不一樣了，大口徑(jing)鋼(gang)(gang)管(guan)(guan)的生產是在大型鋼(gang)(gang)錠(ding)的基礎(chu)上(shang)加(jia)熱、穿孔、定徑(jing)、去頭(tou)等(deng)一系列的繁(fan)瑣工序才能完成。鋼(gang)(gang)板(ban)卷(juan)(juan)管(guan)(guan)費用方面明顯(xian)占(zhan)有優(you)勢。

　　鋼板(ban)卷(juan)管(guan)(guan)(guan)是鋼板(ban)通過(guo)滾筒機把鋼板(ban)成形鋼管(guan)(guan)(guan)坯，然后通過(guo)埋弧焊(han)或(huo)者電焊(han)等焊(han)接成鋼管(guan)(guan)(guan)，然后再(zai)到其他的(de)(de)設備上定(ding)徑，這種管(guan)(guan)(guan)子是單根(gen)生產的(de)(de)效率(lv)低，管(guan)(guan)(guan)子質量不穩定(ding)，尺(chi)寸精度低，但是設備簡單投資(zi)少。而直縫焊(han)管(guan)(guan)(guan)設備效率(lv)高，鋼板(ban)卷(juan)管(guan)(guan)(guan)采用(yong)先(xian)進(jin)的(de)(de)工藝制造，在使(shi)用(yong)中具有良(liang)好的(de)(de)使(shi)用(yong)特點和(he)性能(neng)，能(neng)夠表現重要的(de)(de)價值和(he)作用(yong)。
