溝槽管件是一種新型的鋼管連接管件，也叫卡箍連接，具有很多優(yōu)點(diǎn)。溝槽管件連接技術(shù)也稱卡箍連接技術(shù)，已成為當(dāng)前液體、氣體管道連接的首推技術(shù)，盡管這項(xiàng)技術(shù)在國內(nèi)的開發(fā)時(shí)間晚于國外，但由于其技術(shù)的先進(jìn)性，很快被國內(nèi)市場(chǎng)所接收。從1998年開始研制開發(fā)，來安氣動(dòng)閥門報(bào)價(jià)，經(jīng)過短短幾年的開發(fā)和應(yīng)用，已逐漸取代了法蘭和焊接的兩種傳統(tǒng)管道連接方式。不但技術(shù)上更顯成熟，來安氣動(dòng)閥門報(bào)價(jià)，市場(chǎng)也普遍認(rèn)可，來安氣動(dòng)閥門報(bào)價(jià)，而且得到了國家法規(guī)政策的積極引導(dǎo)。溝槽管件連接技術(shù)的應(yīng)用，使復(fù)雜的管道連接工序變得簡(jiǎn)單、快捷、方便。使管道連接技術(shù)向前邁了一大步。溝槽閘閥重量輕，本體采用高級(jí)球墨鑄鐵制成，重量較傳統(tǒng)閘閥重量減輕約20%-30%，安裝維修方便。來安氣動(dòng)閥門報(bào)價(jià)</p><div
