Kunzwisisa Kukosha Kwemhando Yepombi YeGasi Rakasikwa: X42 SSAW Pipe, ASTM A139 uye EN10219
X42SSAWpombiimhando yepombi yegasi yechisikigo inowanzoshandiswa muindasitiri yemafuta uye gasi.Iyo inogadzirwa uchishandisa yakanyura arc welding process iyo inoburitsa emhando yepamusoro uye yakasimba pombi.X42 SSAW pombi ine simba rakakwirira uye yakanakisa makemikari zvivakwa, zvichiita kuti ikwane kune zvinodiwa zvinodiwa zvekutakura gasi rechisikigo.Kuramba kwayo kwakanakisa mukuora uye kutsemuka kunoita kuti ive sarudzo yekutanga yemapurojekiti ekuvaka mapaipi.
ASTM A139ndeimwe chiyero chakakosha chepombi dzegasi.Iyi dhizaini inovhara electrofusion (arc) yakasungwa yakatwasuka kana spiral seam simbi pombi inoshandiswa kufambisa magasi, chiutsi, mvura uye zvimwe zvinwiwa.ASTM A139 pombi inozivikanwa nekuvimbika kwayo uye kushanda kwenguva refu pasi pemamiriro ekushanda akaomarara.Mapombi aya akagadzirirwa kumirisana nekumanikidza kwakanyanya uye kushanduka kwetembiricha, zvichiita kuti ive yakanakira kutapurirana gasi remusikirwo uye kugovera maapplication.
