油(you)(you)勘石油(you)(you)裝備合金石油(you)(you)鋼(gang)管批(pi)次：

標準中的'批'是指一個檢(jian)(jian)驗單(dan)位，即檢(jian)(jian)驗批。若以交(jiao)(jiao)貨單(dan)位組批，稱交(jiao)(jiao)貨批。當(dang)交(jiao)(jiao)貨批量大(da)時，石油管材，一個交(jiao)(jiao)貨批可(ke)包括幾(ji)個檢(jian)(jian)驗批；當(dang)交(jiao)(jiao)貨批量少時，一個檢(jian)(jian)驗批可(ke)分(fen)為(wei)幾(ji)個交(jiao)(jiao)貨批。

'批'的組成通常有下(xia)列(lie)規定（詳見有關(guan)標準）：

A、每批應(ying)由同(tong)(tong)(tong)一(yi)(yi)牌(pai)號（鋼(gang)級）、同(tong)(tong)(tong)一(yi)(yi)爐(lu)（罐）號或同(tong)(tong)(tong)一(yi)(yi)母爐(lu)號、同(tong)(tong)(tong)一(yi)(yi)規格和同(tong)(tong)(tong)一(yi)(yi)熱處(chu)理制度（爐(lu)次(ci)）的鋼(gang)管組成。

B、對于碳素鋼(gang)結(jie)構管、流體管，可以不同爐（罐(guan)）的同一牌號(hao)、同一規格和同一熱處理制度（爐次）的天(tian)津合金(jin)鋼(gang)管組成(cheng)。

C、焊(han)接鋼管(guan)每批應由(you)同(tong)一牌號（鋼級）、同(tong)一規格的(de)鋼管(guan)組成(cheng)。

⑤鋼和鋼

在GB/T標準中(zhong)，其牌號后面帶(dai)有'A'字者，為鋼，UPTBG石油管材，反之(zhi)為一般鋼。

鋼在下列的部分或全部優于鋼：

A、縮小成分含(han)量范(fan)圍；B、減少有害元素（如硫、磷、銅）含(han)量；

C、保(bao)證(zheng)較高(gao)純凈度（要求(qiu)非金屬夾(jia)雜物含量少）；D、保(bao)證(zheng)較高(gao)力學性能和工藝性能。

⑥縱向和橫向

標準中稱縱向(xiang)是指(zhi)與(yu)加(jia)工(gong)方向(xiang)平行（即順加(jia)工(gong)方向(xiang)）者；橫向(xiang)是指(zhi)與(yu)加(jia)工(gong)方向(xiang)垂(chui)直（加(jia)工(gong)方向(xiang)即鋼(gang)管(guan)軸向(xiang)）。

做沖擊功實驗時，縱(zong)向(xiang)(xiang)試樣的斷口(kou)(kou)(kou)因與加(jia)工方向(xiang)(xiang)垂直。故稱橫向(xiang)(xiang)斷口(kou)(kou)(kou)；橫向(xiang)(xiang)試樣的斷口(kou)(kou)(kou)因與加(jia)工方向(xiang)(xiang)平行，故稱縱(zong)向(xiang)(xiang)斷口(kou)(kou)(kou)。
