[讨论]SC与RC

bsdi

<P>1.华北标92DQ1</P>
<P>SC:穿焊接钢管敷设</P>
<P>RC:穿水煤气管敷设</P>
<P>2.国标00DX001</P>
<P>SC:穿焊接钢管敷设</P>
<P>无RC这种表示</P>
<P>3.焊接钢管按壁厚分为普通焊接钢管和加厚焊接钢管.</P>
<P>焊接钢管按是否镀锌分为非镀锌焊接钢管和镀锌焊接钢管(施工中常见的黑铁管及白铁管).</P>
<P>按照华北标92DQ1 90页提供的数据</P>
<P>与低压流体输送用焊接钢管GBT3092-1993的数据进行比较</P>
<P>与低压液体输送用镀锌焊接钢管GBT3091-1993的数据进行比较</P>
<P>华北标给出的数据基本能达到普通型焊接钢管的标准.</P>
<P>我个人理解,华北标92DQ1是把SC看成是未镀锌普通焊接钢管,把RC看成是普通镀锌焊接钢管.</P>
<P>曾被审图的人多次说过这个问题.</P>
<P>我一直坚持SC,然后注明普通/加厚,镀锌/不镀锌.</P>
<P>今天又被审图的提出,要求把SC改成RC,理由是华北标92DQ1.</P>
<P>我给出不改的回复意见依然是国标00DX001.</P>

gdx8785

<P>不明白审图的怎么会提这样的问题</P>
<P>支持不改</P>

冷若冰

<P>我说几句：</P>
<P>1、你不能阻止别人对你的图纸提出他认为该提的问题。</P>
<P>2、你就用国标答复别人对你的疑问。</P>
<P>3、我认为国标效力强于地区标准。</P>
<P>4、当你用国标答复时，事情是不是解决了呢？</P>

dqlenovo

<P>焊接钢管就是水煤气管</P>

wosuwoxing

<P>SC,RC如楼主</P>
<P>我觉得两者主要区别在于壁厚，适用输送物质不完全相同、压力不同。</P>
<P>RC的性能肯定要比SC好，常用规范没有要求一定用RC，可能化工类、地方标有规定</P>

嘿嘿嘿嘿

<DIV class=quote>以下是引用 <B>bsdi</B></FONT> 在(<I>2008-5-16 9:19:56</I>)的发言
<P>焊接钢管按是否镀锌分为非镀锌焊接钢管和镀锌焊接钢管(施工中常见的黑铁管及白铁管)<BR></P></DIV>
<P>黑的是非镀锌，白的是镀锌</P>
<P>那么SC的到底是黑的还是白的，我看得工地上基本全是黑的</P>

bsdi

<P>1.华北标给出的数据基本能达到普通型焊接钢管的标准.</P>
<P>2.SC仅仅能表示是焊接钢管.</P>

枫叶

<P>哦</P>
<P>那热镀锌钢管是什么个表示，有什么区别</P>
<P>我一直认为SC就是热镀锌</P>
<P>可能是因为在工地呆过，误解了</P>
<P>问题比较严重</P>

阿斯

<P><FONT face=黑体 color=#0000ff size=3>1.焊接钢管可分为普通型和加厚型，</FONT></P>
<P><FONT face=黑体 color=#0000ff size=3>  所谓的加厚型实际上就是管内外均镀锌的焊接钢管。</FONT></P>
<P><FONT face=黑体 color=#0000ff size=3>2.RC和SC都是Run in welded steel conduit的表示，</P>
<P><FONT face=黑体 color=#0000ff size=3>  也就是说都表示穿焊接钢管敷设。</FONT></P>
<P>  有些地方标准图集用RC表示加厚型焊接钢管；</P>
<P>                 用SC表示普通型焊接钢管</P>
<P>3.普通型和加厚型的异同：</P>
<P>  ①公称口径相同的两种管子的公称外径相同；</P>
<P>  ②公称口径相同的两种管子的公称内径不同；</P>
<P>  ③公称口径相同的两种管子的公称壁厚不同；</P>
<P>  ④公称口径相同的两种管子，单位长度的理论重量不同；</P>
<P>  ⑤公称口径相同的两种管子的力学特性和化学特性（即耐腐蚀性）不同；</P>
<P>  ⑥公称口径和长度相同的两种管子的售价不同：）</P>
<P>注：公称口径是近似内径的名义尺寸，它并不表示公称外径减去两个公称壁厚所得的实际内径。</P>
<P>3.图纸表达方法：</P>
<P>  方法一：均用SC表达，并注明哪些地方用普通型，哪些地方要用加厚型；</P>
<P>  方法二：分别用SC和RC表达，同时也应在设计说明中注明各自所表示的含义</P></FONT>

大鼻山

<P><FONT face=宋体 color=#000000 size=4>1、焊接钢管是相对于无缝钢管而言的；</FONT></P>
<P><FONT color=#000000><FONT face=宋体 size=4>2、ASI所谓“加厚型实际上就是管内外均镀锌的焊接钢管”，值得落实；</FONT></FONT></P>
<P><FONT face=宋体 color=#000000 size=4>3、WO斑竹提供的表格很具价值；</FONT></P>
<P><FONT face=宋体 color=#000000 size=4>4、稳妥起见，赞成楼主注明：焊接、普通/加厚、是否镀锌等关键字；</FONT></P>
<P><FONT face=宋体 color=#000000 size=4>5、市政工程，材料表一般要求注明管壁厚度的。民用建筑建议也采用。</FONT></P>

<P>水、煤气输送钢管。是按照冶金部技术标准YB234-63《水、煤气输送钢管》，用普通碳素钢中易焊接的软钢制造的，俗称熟铁管。分为镀锌管(俗称白铁管)和不镀锌管(俗称黑铁管)。其纵向有一条焊缝，一般用炉焊法或高频电焊法焊成，所以又称炉焊对缝钢管或高频电焊对缝钢管。从外观上看，有管端带螺纹(可拧上管箍)和不带螺纹(光管)两种。按照管壁厚度不同分为普通管(适用于Pa≤10kgf／cm2)和加厚管(适于Pa≤16kgf／cm2)。可用手动工具和机械在普通管和加厚管上加工螺纹，因此，便于采用螺纹连接。这种钢管的尺寸规格用公称直径表示，最小公称盲径为6mm，最大公称直径为180mm。目前大量生产15~65mm的普通焊管，适于输送冷热水、蒸气水、煤气、压缩空气、碱液以及其他类似介质，是应用较多的管材之一。<BR></P>
<P>这个YB234-63出版于63年，当时这本规范定价4分钱，这个称呼竟然一直沿用到了现在。目前咱们所谓的SC，指的是管线的敷设方式是穿焊接管敷设，英文是Run in welded steel conduit。</P>
<P>目前咱们使用的焊接钢管的生产和检测标准是GB/T3091-2008《低压流体输送用焊接钢管》，此标准定义了非镀锌焊接钢管以及热镀锌焊接钢管（冷镀锌已经不再允许了）。对应00DX001的标注示意来讲，目前图集所标注的SC应该就是指的是此种焊接钢管。而冶金部的标准YB234-63《水、煤气输送钢管》据说已经在82年合并进入了GB/T3091-1982。目前标注SC，仅可表示是穿焊接管敷设，但是不能说明是否是镀锌或是否加厚。这个就需要设计人特殊注明，以免采购错误。</P>
<P>目前RC这个名词我仅在华北标办的92DQ，98D，05D上见过，以及一些电气参考书上有。个人认为，只标注SC就完全可以代表了各种情况了。</P>
<P>目前据我所知，施工队好像都觉得SC是不镀锌，RC是镀锌钢管，实际这是个认识错误。</P>
