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(he)冷拉(軋)無(wu)縫鋼管(guan)(guan)二(er)種(zhong)。冷拉(軋)管(guan)(guan)又分(fen)為(wei)環狀(zhuang)管(guan)(guan)和(he)異型管(guan)(guan)二(er)種(zhong)。無(wu)縫管(guan)(guan)性(xing)能指標(biao)監(jian)測(ce)可(ke)以依據(ju)液(水(shui))壓試(shi)(shi)(shi)驗、擠(ji)扁試(shi)(shi)(shi)驗、拉伸(shen)實驗、擴口(kou)試(shi)(shi)(shi)驗四個(ge)方面進行(xing)監(jian)測(ce),用以監(jian)測(ce)精密無(wu)縫鋼管(guan)(guan)在然后生(sheng)產制造(zao)生(sheng)產加工(gong)(gong)制作工(gong)(gong)藝過程中自身質量(liang)的能用專(zhuan)業能力(li)。普遍的性(xing)能指標(biao)檢測(ce)有工(gong)(gong)作壓力(li)、擠(ji)扁、彎(wan)曲、擴口(kou)試(shi)(shi)(shi)驗等。
1、液(水)壓試驗(yan):被試無縫管(guan)內(nei)灌進去一定壓力的水,保持壓力一定時(shi)間(試驗(yan)壓力值與穩壓極(ji)管(guan)時(shi)間按標準現定),沒有漏水情況(kuang)。該試驗(yan)為高(gao)品質監測(ce),多見于品如數(shu)檢查。
2、擠扁試(shi)驗(yan):把精密(mi)無縫鋼(gang)管試(shi)樣置(zhi)放二(er)平(ping)板(ban)焊接夾具正中間(jian),在(zai)焊接夾具間(jian)施力致間(jian)距(ju)超出規范數(shu)值(zhi),檢查試(shi)樣變形區(qu)無間(jian)隙(xi)、開裂等(deng)缺(que)陷。
3、 拉伸實驗:把精密無縫鋼管試樣置(zhi)放彎(wan)曲試驗機上,按規范的彎(wan)芯半徑,彎(wan)曲到標準要求的角(jiao)度(du)后,彎(wan)曲位置(zhi)表面無裂紋或開裂等缺陷。
4、擴口試驗將(jiang)精密無(wu)縫鋼管試樣置(zhi)放臺表面,張嘴往上面,將(jiang)按(an)規范(fan)錐度選用(yong)的頂心嵌進(jin)無(wu)縫管中,直(zhi)至試驗直(zhi)徑擴口率超出規范(fan)后(hou),試樣表面無(wu)裂紋或開裂等缺陷(xian)。
