class="khcont">而普通鋼管的焊縫部位是其薄弱環(huán)節(jié)，焊縫質(zhì)量也是影響其整體性能的主要因素。在北方生活過的人一般都有過自來水管或暖氣管在冬天被凍爆的經(jīng)歷，爆的地方一般都是焊縫處。焊管不是無縫鋼管。無縫化鋼管的生產(chǎn)工藝鋼管的無縫化主要是通過張力減徑來完成的，張力減徑過程是空心母材不帶芯棒的連續(xù)軋制過程。在保證母管焊接質(zhì)量的前提下，焊管張力減徑工藝是將焊管整體加熱到950攝氏度以上，再經(jīng)張力減徑機（張力減徑機共有24道次）軋制成各種外徑與壁厚的成品管，采用此工藝所生產(chǎn)的熱軋鋼管與普通的高頻焊管有本質(zhì)的區(qū)別通過加熱爐加熱后其焊縫與母體的金相組織和機械性能可以達到完全一致此外，大口徑無縫鋼管通過多道次的張力減徑機軋制和自動控制使得鋼管的尺寸精度（尤其是管體圓度和壁厚精度）優(yōu)于同類無縫管。　　世界發(fā)達生產(chǎn)的流體管，鍋爐管中已大量采用焊管無縫化工藝，隨著社會的發(fā)展，國內(nèi)熱軋焊管逐步代替無縫管的局面已經(jīng)形成。無縫化鋼管與大口徑無縫鋼管的區(qū)別可以從幾個方面來看首先焊管一般來說都是定尺的，而且一般都是6米，九米或12米。無縫鋼管定尺的非常少，因為定尺出廠加價非常多。第二可以從管頭的橫截面看，如果有銹的話擦干凈，仔細看的話會發(fā)現(xiàn)焊接區(qū)。第三如果酸洗一下，那就明顯了。料涂層涂敷后對鋼管里里的預處理質(zhì)量間接影響到涂層附滅力的高下。
