class="khcont">性精密無縫鋼管有四層結(jié)構(gòu)，內(nèi)部一層是擠壓成型的熱塑性管，在傳輸液體中起密封作用;中間兩層襯里用的是填充碳的聚乙烯管，它具有抵抗長(zhǎng)期受紫外線輻射的能力，并能排除外部靜電。外一層是擠壓成型的厚外部護(hù)罩，用于保護(hù)管子底層不受外部影響。標(biāo)準(zhǔn)柔性精密無縫鋼管適用的額定壓力符合 ANSI 的分類，如等級(jí) 300 相當(dāng)于 5.15MPa ;等級(jí) 400 相當(dāng)于 6.89MPa ;等級(jí) 600 相當(dāng)于 10.3MPa 。海上柔性精密無縫鋼管的設(shè)計(jì)依據(jù)是 API 17J 、 17K 和 RP 17B 。陸上用柔性精密無縫鋼管的設(shè)計(jì)標(biāo)準(zhǔn)稍微偏離了 API 標(biāo)準(zhǔn)的要求，使用 API 17J 分類方法和材料，其壓力、拉力和破壞極限均在規(guī)定的范圍內(nèi)。試驗(yàn)是按照 API RP 17B 的要求進(jìn)行的。終端配件的設(shè)計(jì)要能滿足維持結(jié)構(gòu)的完整性，確保內(nèi)、外擠壓成型層密封的要求，并且能夠保證將拉力和壓力負(fù)載傳遞到管子結(jié)構(gòu)上。終端配件的樣品經(jīng)過爆破和軸向拉力試驗(yàn).</div><p><img

class="khcont">大多數(shù)的精密管是可以進(jìn)行加工的，在加工的時(shí)候一定要和廠家說清楚您的用途是什么，需要什么規(guī)格和型號(hào)的，加工的方式和溫度都要說清楚，這樣的話廠家可以根據(jù)您的描述進(jìn)行自由去選擇加工的方法和方式以及結(jié)構(gòu)。精密管是我們比較熟悉的，在加工的時(shí)候一定要附帶您的聯(lián)系方式，還有相關(guān)的精密管的郵寄地址等等一般的精密管的生產(chǎn)工藝可以分為冷拔與熱軋兩種，冷軋精密管的生產(chǎn)流程一般要比熱軋要復(fù)雜，管坯首先要進(jìn)行三輥連軋，擠壓后要進(jìn)行定徑測(cè)試，如果表面沒有響應(yīng)裂紋后圓管要經(jīng)過割機(jī)進(jìn)行切割，切割成長(zhǎng)度約一米的坯料。然后進(jìn)入退火流程，退火要用酸性液體進(jìn)行酸洗，酸洗時(shí)要注意表面是否有大量的起泡產(chǎn)生，如果有大量的起泡產(chǎn)生說明鋼管的質(zhì)量達(dá)不到響應(yīng)的標(biāo)準(zhǔn)。外觀上冷軋精密管要短于熱軋精密管，冷軋精密管的壁厚一般比熱軋精密管要小，但是表面看起來比厚壁精密管更加明亮，表面沒有太多的粗糙，口徑也沒有太多的毛刺。</div><p><img

GTAW(純Ar氣體保護(hù))：建議采用TIG-R31(含V)焊絲，直徑2.5mm，電流100～140A。如果有一定壁厚，管徑不是很小的話，建議采取GTAW+SMAW。SMAW：焊條采用R337，規(guī)格可以按實(shí)際情況來定。焊接完成后清理飛濺，加熱至350～450℃，保溫并緩冷的后熱措施。12Cr1MoV采用相應(yīng)成分的耐熱鋼焊條，如R310、R312、R317、R316Fe，焊前預(yù)熱250～350℃，焊后回火處理710～750℃。焊補(bǔ)缺陷或焊后不能進(jìn)行熱處理時(shí)，也可采用奧氏體鋼焊條，如A302、A307。這時(shí)，由于焊縫與母材膨脹系數(shù)不同，同時(shí)在長(zhǎng)期高溫工作時(shí)還可發(fā)生碳的擴(kuò)散遷移現(xiàn)象，而易于導(dǎo)致在融合區(qū)發(fā)生破壞。將精密鋼管送入精密鋼管機(jī)組，經(jīng)多道軋輥滾壓，精密鋼管逐漸卷起，形成有開口間隙的圓形精密鋼管，調(diào)整擠壓輥的壓下量，使精密鋼管間隙控制在1~3mm，并使焊口兩端齊平。如間隙過大，則造成鄰近效應(yīng)減少，渦流熱量不足，精密鋼管晶間接合不良而產(chǎn)生未熔合或開裂。如間隙過小則造成鄰近效應(yīng)增大，精密鋼管熱量過大，造成精密鋼管燒損;或者精密鋼管經(jīng)擠壓、滾壓后形成深坑，影響精密鋼管表面質(zhì)量。
