style="text-indent:25px">熱鍍鋅方管：是在使用鋼板或者是鋼帶卷曲成型后焊接制成的方管，并在這種方管的基礎(chǔ)上將方管置于熱鍍鋅池中經(jīng)過一系列化學(xué)反應(yīng)后又形成的一種方管。熱鍍鋅方管的生產(chǎn)工藝較為簡單，且生產(chǎn)效率是很高的，品種規(guī)格也多，這種方管所需要的設(shè)備和資金很少，適合小型鍍鋅方管廠家的生產(chǎn)。但是從強(qiáng)度上來說這種鋼管的強(qiáng)度是遠(yuǎn)遠(yuǎn)低于無縫方管的。鍍鋅方管有熱鍍鋅方管和電鍍鋅方管兩大類。熱鍍鋅方管有濕法、干法、鉛鋅法、氧化還原法等。不同熱鍍鋅方法的主要區(qū)別在鋼管酸浸清洗后，用什么方法活化管體表面提高鍍鋅質(zhì)量。現(xiàn)生產(chǎn)中主要采用干法和氧化還原法，其特點(diǎn)見表。電鍍鋅的鋅層表面十分光滑致密、組織均勻;具有良好的力學(xué)性能和抗腐蝕能力;鋅耗比熱鍍鋅低60%～75%。電鍍鋅在技術(shù)上有一定的復(fù)雜性，但對(duì)單面鍍層，內(nèi)外表面鍍層厚度不同的雙面鍍層，以及薄壁管鍍鋅等皆須采用此法。psp鋼塑復(fù)合壓力管是我國近年來發(fā)展的一種新型管材。</p><div
