content="按無縫鋼管截面形狀尺寸的不同又可分為等壁厚異型無縫鋼管、不等壁厚異型無縫鋼管、變直徑異型無縫鋼管。異型無縫鋼管普遍用于各種結(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，可以極大減輕結(jié)構(gòu)重量"><meta name="keywords"

style="text-indent:25px">按無縫鋼管截面形狀尺寸的不同又可分為等壁厚異型無縫鋼管、不等壁厚異型無縫鋼管、變直徑異型無縫鋼管。異型無縫鋼管普遍用于各種結(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，可以極大減輕結(jié)構(gòu)重量，節(jié)約鋼材。異型無縫鋼管一般是根據(jù)斷截面來區(qū)分的，按材料來說又可分為無縫鋼管異型管，鋁（Al)合金(熔點(diǎn)660℃)異型管，塑料（結(jié)構(gòu):合成樹脂、增塑劑、穩(wěn)定劑、色料)異型管。下面主要介紹一下鋼管異型管。無縫鋼管異型管可分為橢圓形異型鋼管、三角形異型鋼管，嘉興高精密光亮無縫管、六角形異型鋼管、菱形異型鋼管、八角形異型鋼管，嘉興高精密光亮無縫管、半圓形異型鋼圓，不等邊六角形異型鋼管、五瓣梅花形異型鋼管，嘉興高精密光亮無縫管、雙凸形異型鋼管、雙凹形異型鋼管、瓜子形異型鋼管、圓錐形異型鋼管、波紋形異型鋼管。　按無縫鋼管截面形狀尺寸的不同又可分為等壁厚異型無縫鋼管、不等壁厚異型無縫鋼管、變直徑異型無縫鋼管。嘉興高精密光亮無縫管</p><div

style="text-indent:25px">流體無縫管工作原理中的渦街流量計(jì)：渦街流量計(jì)是在流體中安放一根非流線型游渦發(fā)生體,游渦的速度與流體的速度成一定比例，從而計(jì)算出體積流量。渦街流量計(jì)適用與測量液體、氣體或蒸汽。它沒有移動部件，也沒有污垢問題。渦街流量計(jì)會產(chǎn)生噪音，而且要求流體具有較高的流速，以產(chǎn)生旋渦。流體無縫管工作原理中的熱質(zhì)量流量計(jì)：通過測量流體的溫度的升高或熱傳感器降低來測量流體速度。熱式質(zhì)量流量計(jì)沒有移動部件或孔，能精確測量氣體的流量。熱質(zhì)量流量計(jì)是少數(shù)能測量質(zhì)量流量的技術(shù)之一，也是少數(shù)用于測量大口徑氣體流量的技術(shù)。嘉興高精密光亮無縫管結(jié)構(gòu)無縫鋼管與流體無縫鋼管區(qū)別在于有無試壓和探傷？</p><div

style="text-indent:25px">無縫鋼管麻面：其特征是在鋼管表面呈現(xiàn)的成片、點(diǎn)狀細(xì)小凹坑。產(chǎn)生麻面的主要原因是酸洗時產(chǎn)生點(diǎn)狀腐蝕，退火后氧化鐵皮過厚矯直后壓入鋼管表面形成麻面；鋼管保存環(huán)境潮濕，甚至進(jìn)水后發(fā)生點(diǎn)狀銹蝕，在去除銹斑后形成麻面。無縫鋼管斑點(diǎn)：由于無縫鋼管在加工或存放過程中與水(或水汽)接觸未及時處理(如烘干) ,水蒸發(fā)后留下的痕跡稱水斑，如與水接觸時間較長，或水中含有腐蝕性物質(zhì)時會形成銹斑。水斑一般沒有深度，而銹斑往往腐蝕到鋼管表面，去除后仍會存在麻面。</p><p
