1.偽劣厚壁無縫鋼管易出現(xiàn)折疊。折疊是厚壁無縫鋼管表面形成的各種折線，這種缺點往往貫穿整個產(chǎn)品的縱向。產(chǎn)生折疊的原因是由于偽劣廠家追求高效率，壓下量偏大，產(chǎn)生耳子，下一道軋制時就產(chǎn)生折疊，折疊的產(chǎn)品折彎后就會開裂，厚壁無縫鋼管的強(qiáng)度大下降。 </p> <p> 2．偽劣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(yán)重引起厚壁無縫鋼管表面不規(guī)則的凹凸不平的缺點。由于偽劣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(biāo)。 </p> <p> 3．偽劣厚壁無縫鋼管表面易產(chǎn)生結(jié)疤。原因有兩點：1．偽劣厚壁無縫鋼管材質(zhì)不均勻，雜質(zhì)多。2。偽劣材廠家導(dǎo)衛(wèi)設(shè)備簡陋，容易粘鋼，這些雜質(zhì)咬人軋輥后易產(chǎn)生結(jié)疤。 </p> <p> 4．偽劣材表面易產(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(yīng)力的作用，產(chǎn)生裂痕，經(jīng)過軋制后就有裂紋。 </p> <p> <br /> </p> <p> 5．偽劣厚壁無縫鋼管容易刮傷，原因是偽劣材廠家設(shè)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(qiáng)度。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="貴州316L不銹鋼無縫管廠家" src="https://tyunfile.71360.com/WaterMark/UploadFile/JSjbhjs/637246468383886719/7492518.jpg"></div><p> 對于不銹鋼無縫管而言,固溶處理的3個要素是溫度、保溫時間和冷卻速度。不銹鋼無縫管固溶處理有什么作用呢? </p> <p> 1:使不銹鋼無縫管**和成分均勻一致,這對原料尤其重要,因為熱軋管材各段的軋制溫度和冷卻速度不一樣,造成**結(jié)構(gòu)不一致。在高溫下原子活動加劇,σ相溶解,化學(xué)成分趨于均勻,快速冷卻后就獲得均勻的單相**。 </p> <p> 2:消除加工硬化,以利于繼續(xù)冷加工。通過固溶處理,歪扭的晶格恢復(fù),伸長和破碎的晶粒重新結(jié)晶,內(nèi)應(yīng)力消除,鋼絲抗拉強(qiáng)度下降,伸長率上升。 </p> <p> 3:恢復(fù)不銹鋼管固有的耐蝕性能。由于冷加工造成碳化物析出,晶格缺點,使不銹鋼管耐蝕性能下降。固溶處理后不銹鋼無縫管耐蝕性能恢復(fù)到比較好狀態(tài)。 </p> <p>
