材質(zhì)為Q345b的叫做Q195焊管（由于鋼管的焊接處成一條直線(xiàn)故而得名）。 </p> <p> 其中按照用途不同，又不同的后道生產(chǎn)工序(大致可分為腳手架管，流體管，電線(xiàn)套管，支架管，護(hù)欄管等幾種）。 </p> <p> Q195焊管主要是是用鋼板或鋼帶經(jīng)過(guò)彎曲成型，然后經(jīng)焊接制成。按焊縫形式分為Q195焊管和螺旋焊管。按用途又分為一般焊管、鍍鋅焊管、吹氧焊管、電線(xiàn)套管、公制焊管、托輥管、深井泵管、汽車(chē)用管、變壓器管、電焊薄壁管、電焊異型管和螺旋焊管。昆明質(zhì)量焊管市場(chǎng)報(bào)價(jià)焊管生產(chǎn)工藝簡(jiǎn)單，生產(chǎn)效率高，成本低，發(fā)展較快。</p><div

src="http://tyunfile.71360.com/UploadFile/zhongbumaoyi/637208123822666016/3379901.jpg"></div><p> 焊管的種類(lèi)及用途： </p> <p> <br /> </p> <p> 異型管由普通碳結(jié)結(jié)構(gòu)鋼及16Mn等鋼帶焊制的方形管、矩形管、帽形管、空膠鋼門(mén)窗用鋼管，主要用作農(nóng)機(jī)構(gòu)件、鋼窗門(mén)等。電焊薄壁管主要用來(lái)制作家具、玩具、燈具等。當(dāng)前不銹鋼帶制作的薄壁管應(yīng)用很廣，高級(jí)家具、裝飾、欄柵等。螺旋焊管是將低碳碳素結(jié)構(gòu)鋼或低合金結(jié)構(gòu)鋼鋼帶按一定的螺旋線(xiàn)的角度(叫成型角)卷成管坯，然后將管縫焊接起來(lái)制成，它可以用較窄的帶鋼生產(chǎn)大直徑的鋼管。 </p> <p> 螺旋焊管主要用于石油、天然氣的輸送管線(xiàn)，其規(guī)格用外徑*壁厚表示。螺旋焊管有單面焊的和雙面焊的，焊管應(yīng)保證水壓試驗(yàn)、焊縫的抗拉強(qiáng)度和冷彎性能要符合規(guī)定。 </p>一般焊管：一般焊管用來(lái)輸送低壓流體。用Q345B鋼制造。也可采用易于焊接的其它軟鋼制造。鋼管要進(jìn)行水壓、彎曲、壓扁等實(shí)驗(yàn)，對(duì)表面質(zhì)量有一定要求，通常交貨長(zhǎng)度為4-10m，常要求定尺（或倍尺）交貨。焊管的規(guī)格用公稱(chēng)口徑表示（毫米或英寸）公稱(chēng)口徑與實(shí)際不同，焊管按規(guī)定壁厚有普通鋼管和加厚鋼管兩種，鋼管按管端形式又分帶螺紋和不帶螺紋兩種。 <p> Q195焊管形變熱處理在工藝上尚存在一些問(wèn)題，防腐鋼管如螺旋鋼管在淬火過(guò)程中由于管子上溫度不均或冷卻不均而會(huì)引起管子斷面變化、彎曲以及沿管長(zhǎng)方向上的組織性能不均等，還有待于進(jìn)一步研究解決。直縫焊管，用熱軋或冷軋鋼板或鋼帶卷焊制成的鋼管在焊接設(shè)備上進(jìn)行直縫焊接得到的管子都叫直縫焊管。</p><div

很顯然，在制作生產(chǎn)焊管的過(guò)程中，焊接的一道重要的工序。而在進(jìn)行焊接的時(shí)候，其中要注意哪些問(wèn)題呢？首先，必須要合理控制焊接的溫度。也就是說(shuō)，在管坯加熱之前需經(jīng)導(dǎo)向輥導(dǎo)向，以保證焊管的管縫不發(fā)生任何偏斜，在感應(yīng)器中**電流的作用下，使其迅速達(dá)到焊接溫度，在擠壓輥的作用下達(dá)到焊接目的。 </p> <p> 同時(shí)還要注意合理控制焊接的壓力。這是因?yàn)樵诤附舆^(guò)程中，擠壓輥需要對(duì)管坯邊緣施加以足夠的焊接壓力。而焊接壓力是影響焊管焊縫質(zhì)量的主要因素之一。如果壓力過(guò)小，則熔化金屬之間結(jié)合力小，低溶點(diǎn)夾雜物不易擠出，焊縫受力時(shí)易開(kāi)裂。反之，壓力過(guò)大，則容易搭口，焊縫內(nèi)外毛刺大，刨刀刨不平而影響外觀(guān)。碳含量過(guò)高會(huì)導(dǎo)致型鋼的塑性、韌性下降，但適當(dāng)添加也能產(chǎn)生提**度的效果；昆明質(zhì)量焊管市場(chǎng)報(bào)價(jià)</p><p

碳含量過(guò)高會(huì)導(dǎo)致型鋼的塑性、韌性下降，但適當(dāng)添加也能產(chǎn)生提**度的效果；硫使型鋼熱脆，磷則使其冷脆。為什么會(huì)產(chǎn)生應(yīng)力集中？這又會(huì)引發(fā)何種后果，型鋼構(gòu)件上存在一些孔洞、槽口等，或是型鋼內(nèi)部存在缺點(diǎn)等。發(fā)生這種現(xiàn)象后構(gòu)件的應(yīng)力分布平衡被打亂，出現(xiàn)局部高峰應(yīng)力從而造成脆性破壞。
