1、生產(chǎn)制造方法按生產(chǎn)方法不同可分為熱軋管、冷軋管、冷拔管、擠壓管等。、熱軋無(wú)縫管一般在自動(dòng)軋管機(jī)組上生產(chǎn)。實(shí)心管坯經(jīng)檢查并除去表面缺點(diǎn)，截成所需長(zhǎng)度，在管坯穿孔端端面上定心，然后送往加熱爐加熱，在穿孔機(jī)上穿孔。在穿孔同時(shí)不斷旋轉(zhuǎn)和前進(jìn)，在軋輥和頂頭的作用下，管坯內(nèi)部逐漸形成空腔，稱(chēng)毛管。再送至自動(dòng)軋管機(jī)上繼續(xù)軋制。然后經(jīng)均整機(jī)均整壁厚，經(jīng)定徑機(jī)定徑，達(dá)到規(guī)格要求。利用連續(xù)式軋管機(jī)組生產(chǎn)熱軋無(wú)縫鋼管是較先進(jìn)的方法。、若欲獲得尺寸更小和質(zhì)量更好的無(wú)縫管，必須采用冷軋、冷拔或者兩者聯(lián)合的方法。冷軋通常在二輥式軋機(jī)上進(jìn)行，鋼管在變斷面圓孔槽和不動(dòng)的錐形頂頭所組成的環(huán)形孔型中軋制。冷拔通常在。、擠壓法即將加熱好的管坯放在密閉的擠壓圓筒內(nèi)，穿孔棒與擠壓桿一起運(yùn)動(dòng)，使擠壓件從較小的?？字袛D出。此法可生產(chǎn)直徑較小的鋼管。無(wú)錫仁鑫焊管廠主營(yíng)20~200mm之間的各種規(guī)格大小的異型管、圓管、矩形管、方管等冷拔管。江蘇不同規(guī)格圓管哪里好</p><p
