7焊接鋼管可分為直縫焊管和螺旋焊管?？稍谙拦┧芫W(wǎng)中使用。具有強(qiáng)度高，抗應(yīng)變能力強(qiáng)的優(yōu)點(diǎn)，但是其耐腐蝕性能差，應(yīng)作防腐處理。同管徑的鋼管具有不同的厚度，所以在選擇的時(shí)候應(yīng)注明壁厚。直縫焊管：生產(chǎn)工藝簡(jiǎn)單，生產(chǎn)效率高，成本低，發(fā)展較快。螺旋焊管：強(qiáng)度一般比直縫焊管高，能用較窄的坯料生產(chǎn)管徑較大的焊管，還可以用同樣寬度的坯料生產(chǎn)管徑不同的焊管。但是與相同長(zhǎng)度的直縫管相比，宜賓質(zhì)量PVC-U給水管直銷(xiāo)，焊縫長(zhǎng)度增加30~靠前，而且生產(chǎn)速度較低。因此，較小口徑的焊管大都采用直縫焊，大口徑焊管則大多采用螺旋焊。8氯化聚氯乙烯（PVC-C）給水管PVC-C樹(shù)脂為母料，加入抗沖劑，穩(wěn)定劑等輔料經(jīng)高速擠出而成。其特點(diǎn)：1、堅(jiān)固：由于PVC-C較PP-R、PB和PEX堅(jiān)固，故只需較少的掛鉤和支架。PVC－C可耐較大的壓力，在同前列率下，與PP-R、PB和PEX管比較，PVC-C管可使用較小的管徑。2、安裝方便：使用**熔合劑即可連接，安裝時(shí)無(wú)需**工具，即適用于明裝，也適用于暗裝。3、耐腐蝕：PVC-C不易透氧，因此系統(tǒng)內(nèi)的金屬件不會(huì)因氧化而導(dǎo)致腐蝕。4，宜賓質(zhì)量PVC-U給水管直銷(xiāo)、良好的阻燃性：PVC-C的氧指數(shù)為60，燃燒能力很低，離火即熄，不會(huì)產(chǎn)生火滴，宜賓質(zhì)量PVC-U給水管直銷(xiāo)，更能煙霧和有毒氣體的產(chǎn)生。7、不影響水質(zhì)：由溶解試驗(yàn)證實(shí)不影響水質(zhì)，適宜大面積推廣應(yīng)用。宜賓質(zhì)量PVC-U給水管直銷(xiāo)</p><div
