style="text-indent:25px">不銹鋼無(wú)縫管沿其橫截面的周邊上無(wú)接縫的鋼管。根據(jù)生產(chǎn)方法不同分為熱軋管、冷軋管、冷拔管、擠壓管、頂管等，均有各自工藝規(guī)定。材質(zhì)有普通和優(yōu)質(zhì)碳素結(jié)構(gòu)鋼（Q215-A～Q275-A和10～50號(hào)鋼）、低合金鋼（09MnV、16Mn等）、合金鋼、不銹耐酸鋼等。按用途分為一般用途的（用于輸水、氣管道和結(jié)構(gòu)件、機(jī)械零件）和**的（用于鍋爐、地質(zhì)勘探、軸承、耐酸等）兩類(lèi)。不銹鋼無(wú)縫鋼管用途很普遍。一般用途的不銹鋼無(wú)縫鋼管由普通的碳素結(jié)構(gòu)鋼、低合金結(jié)構(gòu)鋼或合金結(jié)構(gòu)鋼軋制，產(chǎn)量較多，主要用作輸送流體的管道或結(jié)構(gòu)零件。.2、根據(jù)用途不同分三類(lèi)供應(yīng)：a、按化學(xué)成分和機(jī)械性能供應(yīng)；b、按機(jī)械性能供應(yīng)；c、按水壓試驗(yàn)供應(yīng)。按a、b類(lèi)供應(yīng)的鋼管，如用于承受液體壓力，也要進(jìn)行水壓試驗(yàn)。3、專(zhuān)門(mén)用途的不銹鋼無(wú)縫管有鍋爐用不銹鋼無(wú)縫管、化工電力用，地質(zhì)用不銹鋼無(wú)縫鋼管及石油用無(wú)縫管等多種。</p><p style="text-indent:25px">不銹鋼無(wú)縫管的連接方式多樣，常見(jiàn)的管件類(lèi)型有壓縮式、壓緊式、活接式、推進(jìn)式、推螺紋式、承插焊接式、活接式法蘭連接、焊接式及焊接與傳統(tǒng)連接相結(jié)合的派生系列連接方式。這些連接方式，根據(jù)其原理不同，其適用范圍也有所不同，但大多數(shù)均安裝方便、牢固可靠。連接采用的密封圈或密封墊材質(zhì)，大多選用符合標(biāo)準(zhǔn)要求的硅橡膠、丁腈橡膠和三元乙丙橡膠等，免除了用戶(hù)的后顧之憂(yōu)。不銹鋼無(wú)縫管卡壓連接步驟：斷管:按所需長(zhǎng)度切斷管材，斷管時(shí)，不可用力過(guò)大，防止管材失圓。去除毛刺:管材切斷后，應(yīng)將毛刺去除干凈、以免割傷密封圈。劃線(xiàn)標(biāo)記:為使鋼管完全插入管件承口，必須在管端對(duì)插入長(zhǎng)度進(jìn)行標(biāo)記畫(huà)線(xiàn)。裝配:密封圈應(yīng)正確安裝在管件的U型槽內(nèi)，將管子插入管件承口內(nèi)，等待壓接。壓接:壓接時(shí)，管件凸起部位放在模具凹形槽內(nèi)，鉗口與管軸線(xiàn)保持垂直。檢查:壓接完成后，使用**量規(guī)對(duì)壓接尺寸進(jìn)行檢查。不銹鋼無(wú)縫管按生產(chǎn)方法不同可分為熱軋管、冷軋管、冷拔管、擠壓管等。</p><div
