1.冷拔或冷軋精密無縫圓管（GB3639-83）是用于機(jī)械結(jié)構(gòu)、液壓設(shè)備的尺寸精度高和表面光潔度好的冷拔或冷軋精密無縫圓管。選用精密無縫圓管制造機(jī)械結(jié)構(gòu)或液壓設(shè)備等，可以很大節(jié)約機(jī)械加工工時，提高材料利用率，同時有利于提高產(chǎn)品質(zhì)量。 2.結(jié)構(gòu)用不銹鋼無縫圓管（GB/T14975-1994）是普遍用于化工、石油、輕紡、醫(yī)療、食品、機(jī)械等工業(yè)的耐腐蝕管道和結(jié)構(gòu)件及零件的不銹鋼制成的熱軋（擠、擴(kuò)）和冷拔（軋）無縫圓管。 3.流體輸送用不銹鋼無縫圓管（GB/T14976-1994）是用于輸送流體的不銹鋼制成的熱軋（擠、擴(kuò)）和冷拔（軋）無縫圓管。 4.異型無縫圓管是除了圓管以外的其他截面形狀的無縫圓管的總稱。按圓管截面形狀尺寸的不同又可分為等壁厚異型無縫圓管（代號為D）、不等壁厚異型無縫圓管（代號為BD）、變直徑異型無縫圓管（代號為BJ）。異型無縫圓管普遍用于各種結(jié)構(gòu)件、工具和機(jī)械零部件。和圓管相比，異型管一般都有較大的慣性矩和截面模數(shù)，有較大的抗彎抗扭能力，可以很大減輕結(jié)構(gòu)重量，節(jié)約鋼材。深圳厚壁不銹鋼無縫管廠商由于在周長相等的條件下，圓面積較大，用圓形管可以輸送更多的流體。</p><div

style="text-indent:25px">部分客戶在使用鍍鋅無縫管的過程中會采用溝槽式鏈接，對無縫管進(jìn)行壓槽，由于熱浸鍍鋅無縫管的鋅層較厚，在破壞性外力的作用下，部分會造成鍍鋅層開裂及剝落,這與鍍鋅無縫管本身質(zhì)量無關(guān)。有客戶會反應(yīng)鍍鋅無縫管上有黃色液體(這液體稱為鈍化液) ，鈍化液能使金屬表面呈鈍態(tài)的溶液。一般用于鍍鋅、鍍鎘和其他鍍層的鍍后處理。目的是在鍍層表面形成能阻止金屬正常反應(yīng)的表面狀態(tài)，提高其抗蝕性，并增加產(chǎn)品美觀。能有效提高圓管的抗腐蝕能力，延長工件的使用壽命。</p><p style="text-indent:25px">熱鍍鋅無縫管工藝是抵御環(huán)境腐蝕的一項較為穩(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4.5mm，根據(jù)規(guī)范GBT13192-2002熱鍍鋅規(guī)范可知。按照國標(biāo)要求，對于4.5mm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)會根據(jù)1964～1974年的大氣暴露試驗結(jié)果。若按照國標(biāo)來計算，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。關(guān)乎生命財產(chǎn)安全大計的消防管，就理當(dāng)選擇安全耐用的熱鍍鋅無縫鋼管了。</p><div

1、倍尺:按訂貨要求的固定尺寸切成整倍數(shù)的稱為倍尺。按倍尺長度交貨時，所交鍍鋅無縫管的長度必須為需方在訂貨合同中指定的長度（叫單倍尺）的整數(shù)倍數(shù)（另加鋸口）。例如，需方在訂貨合同中要求單倍尺長度為2m ，那么，切成雙倍尺時長度即為4m ，切成3 倍尺時即為6m ，并分別加上一個或兩個鋸口量。鋸口量在標(biāo)準(zhǔn)中有規(guī)定。倍尺交貨時，只允許有正偏差，不允許出現(xiàn)負(fù)偏值。 2、短尺:長度小于標(biāo)準(zhǔn)規(guī)定的不定尺長度下限，但不小于允許的較短長度的叫短尺。例如，流體輸送圓管標(biāo)準(zhǔn)中規(guī)定，允許每批有10% 的（按根數(shù)計算） 2-4m長的短尺圓管。4m即為不定尺長度的下限，允許的較短長度為2m。不定尺:（通常長度）鍍鋅無縫管長度一般都是長短不一，這種在標(biāo)準(zhǔn)規(guī)定范圍內(nèi)的叫不定尺。深圳厚壁不銹鋼無縫管廠商</p><p

style="text-indent:25px">無縫管也完全走不出強(qiáng)勢行情，到底是什么因素制約著價格，還是要歸結(jié)于供需面來分析。鋼市走勢的研究回歸于對供需的研究，供需影響著價格，因素的影響減少，站在更理性中立的角度去看市場的供需差，無縫管廠家分析現(xiàn)階段鋼市整體處于區(qū)間震蕩的上部位置，價格向上難有較大的突破。在這種情況下，無縫管未來依然有跌價的空間，現(xiàn)在新建成的產(chǎn)能較多，供應(yīng)壓力持續(xù)，心態(tài)悲觀，二季度無縫管大概率弱勢整理，走出沼澤地還需一定的時日和機(jī)會。深圳厚壁不銹鋼無縫管廠商</p><p
