精密無縫鋼管實體廠家 在線報價
精密無縫鋼管因其生產加工制作工藝不同,又分為熱扎(擠壓加工)無縫鋼管和冷拉(la)(軋)無(wu)縫(feng)鋼(gang)管二種。冷拉(la)(軋)管又分為環狀管和異型管二種。無(wu)縫(feng)管性能指標監(jian)測可(ke)以依據液(水)壓試驗(yan)、擠扁試驗(yan)、拉(la)伸實驗(yan)、擴口(kou)試驗(yan)四(si)個方面進行監(jian)測,用(yong)以監(jian)測精(jing)密無(wu)縫(feng)鋼(gang)管在然后生(sheng)產制造生(sheng)產加工制作工藝過(guo)程中自身(shen)質(zhi)量的(de)能用(yong)專業能力。普(pu)遍的(de)性能指標檢測有工作壓力、擠扁、彎曲(qu)、擴口(kou)試驗(yan)等。
1、液(水)壓(ya)試(shi)(shi)驗:被試(shi)(shi)無(wu)縫管(guan)內灌進(jin)去一定(ding)壓(ya)力的水,保持壓(ya)力一定(ding)時(shi)間(試(shi)(shi)驗壓(ya)力值與穩壓(ya)極(ji)管(guan)時(shi)間按標準現定(ding)),沒有漏水情況。該試(shi)(shi)驗為高品(pin)質監(jian)測(ce),多見于品(pin)如數檢查。
2、擠扁試驗:把精密(mi)無縫鋼管試樣(yang)置(zhi)放二平(ping)板焊(han)(han)接(jie)夾具正中間(jian),在(zai)焊(han)(han)接(jie)夾具間(jian)施力致(zhi)間(jian)距超出規范(fan)數值(zhi),檢查試樣(yang)變形區(qu)無間(jian)隙、開裂等缺陷。
3、 拉伸實驗:把精密無縫鋼管試(shi)樣置放彎(wan)曲(qu)試(shi)驗(yan)機上(shang),按(an)規范的彎(wan)芯半(ban)徑,彎(wan)曲(qu)到標準要(yao)求的角度后(hou),彎(wan)曲(qu)位(wei)置表面無裂紋或開裂等缺陷。
4、擴口試(shi)驗將精密無(wu)縫鋼(gang)管試(shi)樣(yang)置放(fang)臺表(biao)面(mian)(mian),張(zhang)嘴往上面(mian)(mian),將按(an)規范(fan)錐度(du)選用(yong)的(de)頂心(xin)嵌(qian)進無(wu)縫管中,直至(zhi)試(shi)驗直徑擴口率(lv)超出規范(fan)后,試(shi)樣(yang)表(biao)面(mian)(mian)無(wu)裂紋或開裂等缺陷(xian)。
