Tinokugamuchirai kublog redu! Muchinyorwa chanhasi, tichakurukura nezveAmerican Standard ASTM A500 Square Pipe uye kukosha kwayo muindasitiri yekutumira simbi kunze kwenyika. Semugadziri wemapaipi esimbi anotungamira muASTM A500 uye mutengesi, Shandong Zhongao Steel Co., LTD. yakazvipira kupa zvigadzirwa zvesimbi zvemhando yepamusoro zvinosangana nezvinodiwa zvepasi rose. ASTM A500 square pipe iri kutora nzvimbo yakakosha mumusika, uye tichanyatsoongorora mamakisi ayo esimbi, kunyanya ASTM A500 Grade A neASTM A500 Grade B. Pamusoro pezvo, tichaongorora zvakanakira mapaipi esimbi anodhonzwa nechando. Saka, ngatitangei!
1. Nzwisisa pombi yeASTM A500 square:
Machubhu eASTM A500 square tube anogadzirwa zvichienderana neAmerican Society for Testing and Materials (ASTM) A500 standard, iyo inonyanya kushandiswa pamachubhu esimbi yakasungirirwa uye isina musono yecarbon steel. Zita rayo rekuti "structural tube" rinoratidza kushandiswa kwayo kukuru mumapurojekiti akasiyana-siyana ekuvaka akadai sezvivakwa, mabhiriji nezvimwe zvivakwa zvinotsigira. Nekuda kwekugadzirwa kwesimbi yakasanganiswa necarbon steel yepamusoro, chubhu iyi ine simba rakasimba, kugara kwenguva refu uye kuvimbika.
2. Kutumira kunze kwesimbi kubva kumapombi esimbi akajairwa eASTM A500:
Kutengeswa kwesimbi kunze kwenyika kunoita basa guru mukutengeserana kwenyika, zvichipa zvinhu zvakagadzirwa kunyika dzepasi rose. Izvi zvinosimudzira kukura kwehupfumi nekuvandudzwa kwezvivakwa. Kuti kuve nechokwadi chekuti simbi inotengeswa kunze kwenyika yakanaka, kutevedzera mitemo yepasi rose kwakakosha. ASTM A500 standard inovimbisa kunaka uye kushanda zvakanaka kwemachubhu emativi, zvichiita kuti ive sarudzo yekutanga yekutengeswa kwesimbi kunze kwenyika. Nekuda kuri kuramba kuchiwedzera kudiwa kwemachubhu emhando yepamusoro, ASTM A500 Square Pipe yave chigadzirwa chakakosha kune nyika dziri kutsvaga simbi yakavimbika inotengeswa kunze kwenyika.
3. ASTM A500 Giredhi A neASTM A500 Giredhi B:
Sekureva kweAmerican Standard ASTM A500, kune mhando mbiri huru dzesimbi dzinowanzo shandiswa: ASTM A500 Giredhi A uye ASTM A500 Giredhi B. Hunhu hwemakanika uye zvirevo zvemhando idzi dzesimbi zvinosiyana. ASTM A500 Giredhi A inopa chimiro chesimbi.
