class="khcont">厚壁無縫鋼管外表經(jīng)常有麻面現(xiàn)象。麻面是由于軋槽磨損嚴重引起厚壁無縫鋼管表面不規(guī)則的凹凸不平的缺陷。由于厚壁無縫鋼管廠家要追求利潤，經(jīng)常出現(xiàn)軋槽軋制超標。厚壁無縫鋼管表面易產(chǎn)生結(jié)疤。原因有兩點：厚壁無縫鋼管材質(zhì)不均勻，雜質(zhì)多。材廠家導衛(wèi)設備簡陋，容易粘鋼，這些雜質(zhì)咬人軋輥后易產(chǎn)生結(jié)疤。材表面易產(chǎn)生裂紋，原因是它的坯料是土坯，土坯氣孔多，土坯在冷卻的過程中由于受到熱應力的作用，產(chǎn)生裂痕，經(jīng)過軋制后就有裂紋。<br /> 厚壁無縫鋼管容易刮傷，原因是材廠家設備簡陋，易產(chǎn)生毛刺，刮傷厚壁無縫鋼管表面。深度刮傷降低厚壁無縫鋼管的強度。厚壁無縫鋼管無金屬光澤，呈淡紅色或類似生鐵的顏色，原因有兩點它的坯料是土坯。材軋制的溫度不標準，他們的鋼溫是通過目測的，這樣無法按規(guī)定的奧氏體區(qū)域進行軋制，厚壁無縫鋼管的性能自然就無法達標。厚壁無縫鋼管的橫筋細而低，經(jīng)常出現(xiàn)充不滿的現(xiàn)象，原因是廠家為達到大的負公差，成品前幾道的壓下量偏大，鐵型偏小，孔型充不滿。</div><p><img

class="khcont">無縫方矩管加工是利用電解的原理，通過金屬離子的電解過程在產(chǎn)品表面沉積一層金屬或合金層，以改變產(chǎn)品表面物理和化學性能，終使得鍍鋅板具有耐磨性、裝飾性和耐沖擊性等，此外還能夠根據(jù)具體產(chǎn)品的特殊要求而涂覆某種特定的鍍層，如光能性和電磁性鍍層等，這樣可充分擴大方矩管的應用領(lǐng)域。方矩管方矩管生產(chǎn)規(guī)格為：方管：20×20×3～500×500×16mm；矩形管：20×30×3～400×600×16mm.方矩管加工電鍍工藝主要有預處理、電鍍及鍍后處理等過程，鍍層的質(zhì)量取決于材料的電鍍過程，而電鍍過程又受很多因素的影響，歸納六大因素如下：鋅含量：鋅塊的鋅純度越高，其光亮范圍越窄，汽車板就更易獲得較厚的鍍層，鍍層中鐵含量也會較低；當鋅塊的純度太低時，其光亮范圍會較寬，要達到規(guī)定的鋅層厚度就需要更長的時間，這就會導致鍍鋅層中鐵含量較高。</div><p><img

class="khcont6">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。</div><p><img
