Flattening Property
Pane tembiricha yemumba (5 ℃ ~ 35 ℃), iyo weld inotenderera kune yekumanikidza nzira.Dzvinyirira muenzaniso pakati pemapuratifomu maviri kusvika chinhambwe H pakati pepuratifomu chasvika zvikamu zviviri kubva muzvitatu zvekunze dhayamita yepakati simbi pombi, uye ipapo tarisa pakatsemuka.
Bendability
Kana DN≤50A, ita bvunzo yekukotama.
Paunenge uchikotama kune radius yemukati ye90 ° ye6 nguva yekunze kwepaipi, chidimbu chekuedza hachizobudisi chero kuputika.Usati wakotama, yera kona yekukotama kubva panzvimbo yakatwasuka.
Hydraulic Test kana Nondestructive Test (NDT)
Imwe neimwe pombi inofanirwa kunge iri Hydraulic Test kana Nondestructive Test.
Hydraulic Test
Iyo pombi inofanirwa kumira 2.5MPa kweinenge 5 s, isina kuvuza.
Nondestructive Test
Nondestructive hunhu hwekuyedza hunogona kushandiswa kune ultrasonic kana eddy ikozvino yekuongorora, uye pombi inosangana neinotevera isina kuparadza yekuyedza maitiro.
Kuongororwa kwe ultrasonic, mareferensi samples anotsanangurwa muJIS G 0582 ane EU kirasi referensi zviyero achashandiswa seyero yearamu;chero chiratidzo chinobva papombi chakaenzana kana chikuru kupfuura chiyero chearamu chichashandiswa seyero yearamu.chiratidzo chichashandiswa seyero yearamu;chero chiratidzo chinobva papombi chinoenzana kana chikuru kupfuura mwero wearamu chichava chikonzero chekurambwa.
