熱浸鍍鋅焊接鋼管分為普通鋼管、加厚鋼管、和無(wú)縫鋼管，當(dāng)系統(tǒng)壓力小于等于1.0MPA時(shí)，可采用熱浸鍍鋅焊接鋼管；當(dāng)系統(tǒng)壓力在1.0-1.6間時(shí)，應(yīng)采用熱浸鍍鋅焊接加厚鋼管；當(dāng)系統(tǒng)壓力大于1.6時(shí)應(yīng)采用熱浸鍍鋅無(wú)縫鋼管。 </p> <p> 5. 管道接口：卡箍連接、螺紋連接、法蘭和焊接。系統(tǒng)管道的連接鍍鋅鋼管應(yīng)采用槽式連接件(卡箍)、螺紋或法蘭連接。報(bào)警閥前采用內(nèi)壁不防腐鋼管時(shí)，可焊接連接。系統(tǒng)中管徑DN小于等于80時(shí)，采用螺紋連接，管徑DN大于80時(shí)，可采用卡箍連接、法蘭連接或焊接。因卡箍連接要求的施工空間小，便于維修，是目前比較好的連接方式。 </p> <p> <br /> </p><p> 球墨鑄鐵管和柔性鑄鐵管是兩種我們現(xiàn)在經(jīng)常用的水管，這兩中水管的名字相像，所以我們經(jīng)常會(huì)將這兩種管道給弄混，所以現(xiàn)在我們就來(lái)講一講這兩種管道的區(qū)別，以便于我們區(qū)分它們。 </p> <p> 球墨鑄鐵管是一種由球墨鑄鐵制成的質(zhì)量給排水管，由離心球墨鑄鐵機(jī)加球化劑，高速離心鑄造而成。管道經(jīng)退火、內(nèi)外防腐處理后，用橡膠密封圈密封。用于市政、污水管道、住宅、城市和消防。 </p> <p> 在安裝上：球墨鑄鐵管需要用機(jī)械來(lái)配合進(jìn)行安裝，柔性鑄鐵管是安裝于建筑物地下或者室內(nèi)，人工安裝即可完成； </p> <p> 安裝接口上：球墨鑄鐵管常用的接口是T型承接口，柔性鑄鐵管的安裝接口方式有A/B/W三種方式。廣西**球墨鑄鐵管各種球墨鑄鐵管球墨鑄鐵管現(xiàn)貨。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
