无(wu)缝(feng)钢管(guan)(guan)(guan)(guan)(guan)是由整支圆钢穿(chuan)孔(kong)而成的，表面上(shang)没有(you)焊缝(feng)的钢管(guan)(guan)(guan)(guan)(guan)，称之为无(wu)缝(feng)钢管(guan)(guan)(guan)(guan)(guan)。根(gen)据生产方(fang)(fang)法，无(wu)缝(feng)钢管(guan)(guan)(guan)(guan)(guan)可(ke)分热轧无(wu)缝(feng)钢管(guan)(guan)(guan)(guan)(guan)、冷轧无(wu)缝(feng)钢管(guan)(guan)(guan)(guan)(guan)、冷拔无(wu)缝(feng)钢管(guan)(guan)(guan)(guan)(guan)、挤压(ya)无(wu)缝(feng)钢管(guan)(guan)(guan)(guan)(guan)、顶管(guan)(guan)(guan)(guan)(guan)等(deng)。按照断面形状，无(wu)缝(feng)钢管(guan)(guan)(guan)(guan)(guan)分圆形和异形两种，异形管(guan)(guan)(guan)(guan)(guan)有(you)方(fang)(fang)形、椭圆形、三角形、六角形、瓜(gua)子形、星(xing)形、带翅管(guan)(guan)(guan)(guan)(guan)多(duo)种复杂形状。****直径达900mm，最小直径为 4mm。根(gen)据用途不同，有(you)厚壁无(wu)缝(feng)钢管(guan)(guan)(guan)(guan)(guan)和薄壁无(wu)缝(feng)钢管(guan)(guan)(guan)(guan)(guan)。无(wu)缝(feng)钢管(guan)(guan)(guan)(guan)(guan)主要用做(zuo)石油地(di)质(zhi)钻探(tan)管(guan)(guan)(guan)(guan)(guan)、石油化工用的裂(lie)化管(guan)(guan)(guan)(guan)(guan)、锅炉(lu)管(guan)(guan)(guan)(guan)(guan)、轴承管(guan)(guan)(guan)(guan)(guan)以及汽车、拖拉机、航空用高精度结构(gou)钢管(guan)(guan)(guan)(guan)(guan)。

分类

沿其(qi)横(heng)截面的周边上无接缝的钢(gang)管(guan)(guan)。根(gen)据(ju)生产(chan)方法不同分为热轧管(guan)(guan)、冷轧管(guan)(guan)、冷拔管(guan)(guan)、挤(ji)压管(guan)(guan)、顶管(guan)(guan)等(deng)，均(jun)有各自工艺规定。

材质有普通和优质碳素结构(gou)钢(gang)（Q215-A～Q275-A和10～50号钢(gang)）、低合金(jin)钢(gang)（09MnV、16Mn等）、合金(jin)钢(gang)、不(bu)锈耐(nai)酸(suan)钢(gang)等。

按用(yong)途(tu)分为一般用(yong)途(tu)的（用(yong)于输水、气管道和结构件(jian)、机(ji)械零(ling)件(jian)）和专(zhuan)用(yong)的（用(yong)于锅炉、地质勘(kan)探、轴承、耐酸(suan)等）两类。
