style="text-indent:25px">熱鍍鋅無縫管工藝是抵御環(huán)境腐蝕的一項(xiàng)較為穩(wěn)定可靠的鋼材表面處理方案，影響熱鍍鋅的因素有很多，如：鋼材基材成分，表面狀態(tài)(如粗糙程度)，基材內(nèi)應(yīng)力，幾何尺寸等，其中基材的厚度對熱鍍鋅的厚度影響較大，一般較厚的圓管熱鍍鋅厚度也就越大。下面以4.5mm厚度的鍍鋅無縫管為例來說明不同環(huán)境下的使用年限。假設(shè)無縫管基材的厚度為4，廣東冷拔無縫管采購.5mm，根據(jù)規(guī)范GBT13192-2002熱鍍鋅規(guī)范可知。按照國標(biāo)要求，廣東冷拔無縫管采購，對于4，廣東冷拔無縫管采購.5mm基材，局部厚度不應(yīng)小于55μm，平均厚度不應(yīng)小于70μm。根據(jù)日本熱鍍鋅協(xié)會(huì)根據(jù)1964～1974年的大氣暴露試驗(yàn)結(jié)果。若按照國標(biāo)來計(jì)算，平均厚度為70μm，則附鋅量為70x7.2=504g/m2，在四種不同的環(huán)境下可使用的年限約為：重工業(yè)地帶：12.57年，每年的腐蝕度為40.1;海岸地帶：46.66年，每年的腐蝕度為10.8;郊外地帶：93.33年，每年的腐蝕度為5.4;城市地帶：28.8年，每年的腐蝕度為17.5。圓管按橫截面積形狀的不同可分為圓管和異型管。廣東冷拔無縫管采購</p><div

style="text-indent:25px">鍍鋅無縫管由于有鋅的保護(hù)，不容易生銹，鍍鋅圓管比無縫圓管輕，如果是用于陽臺(tái)的話，較好用鍍鋅光管，無縫圓管太用不太適合用于陽臺(tái)，因?yàn)闊o縫圓管管壁厚，自然重量就重，而且無縫圓管的成本要比鍍鋅圓管的成本要高，還有鍍鋅圓管很耐用，使用年限要遠(yuǎn)遠(yuǎn)超過無縫圓管。如果質(zhì)量過硬，使用二十多年應(yīng)該不成問題，當(dāng)然焊接和油漆也要做好，不讓會(huì)影響鍍鋅圓管的使用年限。用途區(qū)別：鍍鋅圓管一般就是用來做柵欄、圍欄、護(hù)欄、陽臺(tái)護(hù)欄的。普遍使用于市政工程、道路、工廠、學(xué)校、開發(fā)區(qū)、園林、廣場、小區(qū)等場所。廣西精密無縫管廠家石油鉆探管是用于石油鉆探兩端內(nèi)加厚或外加厚的無縫管。</p><div

style="text-indent:25px">無縫管是經(jīng)過熱軋冷拔生產(chǎn)的，一般會(huì)存在壁厚不均的現(xiàn)象，主要體現(xiàn)為直線狀壁厚不均、頭尾部壁厚偏厚、偏薄等等。這些都是什么原因造成的呢？ 1、芯棒頂穿鞍座高度調(diào)整不合適，芯棒頂穿時(shí)接觸到某一面的毛管，致使毛管在接觸面上降溫過快，造成壁厚不均甚至拉凹缺陷。 2、頂桿的剛度不夠，在穿孔過程中產(chǎn)生彎曲，使頂頭不能保持對中位置，從而使穿出的毛管壁厚不均。 3、單、雙機(jī)架壓下量不均，會(huì)造成不銹圓管單機(jī)架方向超薄或者超厚；雙機(jī)架方向超薄或超薄的直線型對稱偏差。 4、連軋軋輥間隙過小或過大、軋管機(jī)中心線偏差、連軋調(diào)整不當(dāng)、堆鋼和拉鋼軋制，都會(huì)造成管壁厚度不均勻。還有安全臼斷裂，內(nèi)外輥縫差大，會(huì)造成圓管直線型非對稱偏差。</p><p

style="text-indent:25px">熱鍍鋅工藝是將表面清潔的金屬材料或零件浸在熔融的鋅液中，利用界面發(fā)生的物理化學(xué)反應(yīng)，在表面形成一層金屬鋅的過程。熱鍍鋅也叫熱浸鋅和熱浸鍍鋅：是一種有效的金屬防腐方式，主要用于各行業(yè)的金屬結(jié)構(gòu)、設(shè)施、材料等的表面防腐。基于熱鍍鋅層的特性，熱鍍鋅無縫管發(fā)生以下特性的原因主要有：熱鍍鋅層表面不光滑：這個(gè)可能和鋅液的凈化和合金的應(yīng)用有關(guān)。如果加工中鋅液處于凈化期以前，鋅液中的懸浮Zn-Fe合金粒子會(huì)粘附到鍍鋅層表面，但不可能破壞既有的Zn-Fe合金層+Zn層。如果是合金類型中選擇的Zn-Ni合金用量較大，也會(huì)產(chǎn)生懸浮顆粒，粘附在鍍鋅層表面，造成表面不平。無縫管較低使用成本：因?yàn)闊o縫管的壽命太長了，所以將初期投入之鍍鋅費(fèi)用平均分?jǐn)傊?，就顯微不足道了。廣東冷拔無縫管采購</p><p
