style="text-indent:25px">鍍鋅鋼管表面有熱浸鍍或電鍍鋅層的焊接鋼管。鍍鋅可增加鋼管的抗腐蝕能力，延長(zhǎng)使用壽命。鍍鋅管的用途很廣，除作輸水、煤氣、油等一般低壓力流體的管線管外，還用作石油工業(yè)特別是海洋油田的油井管、輸油管，化工焦化設(shè)備的油加熱器、冷凝冷卻器、煤餾洗油交換器用管，以及棧橋管樁、礦山坑道的支撐架用管等。熱鍍鋅管是使熔融金屬與鐵基體反應(yīng)而產(chǎn)生合金層，從而使基體和鍍層二者相結(jié)合。熱鍍鋅是先將鋼管進(jìn)行酸洗，為了去除鋼管表面的氧化鐵，酸洗后，通過(guò)氯化銨或氯化鋅水溶液或氯化銨和氯化鋅混合水溶液槽中進(jìn)行清洗，然后送入熱浸鍍槽中。龍港圓管型號(hào)H型鋼與焊接工字鋼相比，成本低，殘余應(yīng)力小，無(wú)需昂貴的焊接材料和焊縫檢測(cè)，節(jié)約鋼結(jié)構(gòu)制作成本。</p><div

style="text-indent:25px">H型鋼是當(dāng)今鋼結(jié)構(gòu)建筑中應(yīng)用普遍的型材，它與工字鋼相比有很多區(qū)別。首先是翼緣，其次翼緣內(nèi)表面沒(méi)有傾斜度，上下表面平行。H型鋼的截面特性要明顯優(yōu)于傳統(tǒng)的工字鋼、槽鋼和角鋼。H型鋼，是一種截面面積分配更加優(yōu)化、強(qiáng)重比更加合理的經(jīng)濟(jì)斷面高效型材，因其斷面與英文字母“H”相同而得名。H型鋼的兩條外邊內(nèi)側(cè)沒(méi)有斜度，是平直的。這使得H型鋼的焊接拼接比工字鋼操作簡(jiǎn)單，單位重量的力學(xué)性能更好，可以節(jié)省大量的材料和施工時(shí)間。熱鍍鋅鋼管的合金層與純鋅層、鋼管基體融為一體，故其耐腐蝕能力強(qiáng)。玉環(huán)鋼筋工程量計(jì)算</p><p
