主要材料及機械性能：
|
 本公司采用原材料主要為上海寶鋼產(chǎn)St35、St37.4（10#）、St45（20#）、St55（35#）、Ck45（45#）、St52（16Mn）、lCrl8Ni9Ti、35CrMo等。
本公司生產(chǎn)的鋼管機械性能、工藝性能均極佳，鋼管能承受高壓、沖擊，特別適合液壓機械和汽配行業(yè)。鋼管能進行任何角度的冷彎變形，擴口、壓扁無裂縫，適合與需要各種彎曲變形加工的行業(yè)。
附表《常用牌號化學成分、機械性能表》 本公司提供的鋼管均符合或優(yōu)于表中所列各項數(shù)據(jù)。
|
|
尺寸精度
|
1、 常用規(guī)格尺寸公差見附表《常用規(guī)格尺寸公差對照表》
2、 鋼管交貨長度：通常為6米，（其它交貨長度面議）
|
|
壓力
|
|
壓力理論計算公式
|
|
其中：
p=試驗壓力kgf/cm2 或 N/mm2
S=鋼管公稱壁厚
D=鋼管公稱外徑
R=允許壓力kgf/cm2或N/mm2,為相應(yīng)鋼號最低屈服點的80%
|
|
重量
|
定尺按理論重量計算，不定尺按實際重量結(jié)算。
鋼管的理論重量按系列公式計算:W=（D-S）×S×0.02466
其中W=鋼管的每米重量；S=鋼管的公稱壁厚；D=鋼管的公稱外徑
|
|
表面質(zhì)量
|
鋼管內(nèi)、外表面清潔、無氧化層、無裂縫、折疊、軋折、結(jié)疤、離層、發(fā)紋、。
鋼管具有與所使用的制造方法及熱處理方法相對應(yīng)的內(nèi)外表面狀態(tài)（如劃痕、凸起、凹槽），但其深度不超得過0.025mm（此要求高于DIN2391的標準）
|
|
鋼管防腐包裝及運輸
|
|
鋼管涂防銹油、二端塑封、內(nèi)層塑料薄膜、外層麻布或木箱包裝。
注：鋼管開具質(zhì)量證明書。
