Kunzwisisa ASTM A139: Mutsipa weSAWH Pipe uye Spiral Welded Pipe Applications

Munyika yemapaipi emaindasitiri, makodhi nemitemo inodzora zvinhu zvinoshandiswa zvakakosha pakuona kuchengetedzeka, kugara kwenguva refu uye kushanda zvakanaka. Imwe yemitemo iyi ndeiyiASTM A139, iyo inoita basa rakakosha mukugadzirwa nekushandiswa kwemapombi eSAWH (spiral arc welded hollow) nemapombi espiral welded. Mublog rino, tichakurukura kukosha kweASTM A139, hunhu hwepombi yeSAWH, uye zvakanakira Pipe yeHelical Welded mumaindasitiri akasiyana-siyana.

Chii chinonzi ASTM A139?

ASTM A139 ipfungwa yakagadzirwa neAmerican Society for Testing and Materials (ASTM) iyo inotsanangura zvinodiwa papombi yesimbi yakasungirirwa nemagetsi (arc). Iyi chiyero inoshanda zvikuru kumapombi anoshandiswa kutakura mvura nemagasi. Iyi pfungwa inosanganisira mhando dzakasiyana dzemhando dzesimbi uye inoita kuti mapaipi anogadzirwa akwane hunhu hwakasiyana hwemakanika uye makemikari.

Mutemo weASTM A139 wakakosha kune vagadziri nemainjiniya nekuti unopa gwara pakugadzira, kusanganisira matekiniki ekunamira uye matanho ekudzora mhando anofanirwa kutorwa. Nekutevedzera mitemo iyi, vagadziri vanogona kuve nechokwadi chekuti zvigadzirwa zvavo zvakavimbika uye zvakakodzera kushandiswa kwakasiyana-siyana, kubva pakufambisa mafuta negesi kusvika pakushandiswa kwezvivakwa.

Basa repombi yeSAWH

Pombi yeSAWH kana kuti pombi yesimbi yakasungirirwa ine spiral arc yakasungirirwa ine hollow imhando yepombi yakasungirirwa yakagadzirwa nekuspirally welding flat steel strips kuita chimiro che cylindrical. Nzira iyi yekugadzira inobvumira kugadzirwa kwemapombi ane dhayamita hombe akasimba uye akareruka. Tekinoroji yesimbi yakasungirirwa inoshandiswa muMapaipi eSAWH inopa mabhenefiti akawanda, anosanganisira:

1. Kubudirira Kwemari:Maitiro ekugadzira mapaipi eSAWH anowanzo dhura mari kupfuura nzira dzechinyakare, zvichiita kuti ive sarudzo inokwezva kumapurojekiti makuru.

2. KUSHANDA-SHANDA:Pombi yeSAWH inogona kugadzirwa muhukuru hwakasiyana-siyana uye ukobvu, zvichiita kuti ive yakakodzera kushandiswa kwakasiyana-siyana, kusanganisira mvura, masisitimu emvura yakasviba, uye zvikamu zvechivakwa.

3. Simba Rakawedzerwa:Kuvaka kwakasungirirwa kwesimbi kunopa simba rakawedzerwa uye kuramba kumanikidzwa kwekunze, zvichiita kuti pombi yeSAWH ive yakakodzera munzvimbo dzine kushushikana kwakanyanya.

Mabhenefiti epombi dzakasungirirwa dzakatenderedzwa

Mapaipi akasungirirwa espiral imwe mhando yemapaipi akasungirirwa akagadzirwa uchishandisa tekinoroji yekushongedza espiral. Nzira iyi inosanganisira kuputira simbi yakatenderedza mandrel uye kuishongedza mudenderedzwa rinotenderera.Pipe yeHelical Welded inopa mabhenefiti akawanda, anosanganisira:

1. Hunhu hwekuyerera kwemvura hwakavandudzwa:Nzvimbo yemukati yakatsetseka yeHelical Welded Pipe inoderedza kusagadzikana uye inowedzera kuyerera kwemvura, zvichiita kuti ive yakakodzera kushandiswa muindasitiri yemafuta negesi.

2. KUDERERA KWAKADERERA:Dhizaini yedenderedzwa remadziro inobvumira madziro akatetepa pasina kukanganisa simba, zvichiita kuti pombi ive yakareruka uye ive nyore kubata nekutakura.

3. Hurefu Hunogona Kugadziriswa:Pipe yeHelical Welded inogona kugadzirwa nehurefu hwakareba, zvichideredza huwandu hwemajoini anodiwa mupombi uye zvichideredza mukana wekubuda kwemvura.

Mukupedzisa

Muchidimbu, ASTM A139 ndiyo nzira huru yekugadzira pombi yeSAWH nepipi yakasungirirwa inotenderera, ichiva nechokwadi chekuti zvinhu izvi zvakakosha zvinosangana nezvinodiwa zvekuchengetedza uye mashandiro. Hunhu hwakasiyana hweSAWH nepipi yakasungirirwa inotenderera inoita kuti ive yakakosha mumaindasitiri akasiyana kubva pakuvaka kusvika kusimba. Sezvo tekinoroji ichiramba ichifambira mberi, kukosha kwekutevedzera mitemo yakagadzwa seASTM A139 kuchakura chete kuona kuti zvivakwa zvatinovimba nazvo zvinoramba zvakachengeteka uye zvichishanda zvakanaka. Kunyangwe uri mainjiniya, kontrakita, kana maneja wepurojekiti, kunzwisisa mitemo iyi uye zvakanakira mhando idzi dzepipi kwakakosha pakuita sarudzo dzakangwara pamapurojekiti ako.
