Spiral welded simbi pombi

Spiral welded simbi pombi inozivikanwawo se spiral simbi pombi uye spiral welded pombi, iri kushandisa yakaderera kabhoni structural simbi kana yakaderera alloy simbi tambo zvichienderana nekona ye spiral line (inonzi kuumba angle) yakakungurutswa muchubhu, uyezve. iyo chubhu inobatanidzwa pamwe chete yakagadzirwa, inogona kuva yakamanikana tambo kugadzirwa yakakura dhayamita simbi pombi.Iyo coil inonyanya kushandiswa kuoiri uye gasi mapaipi, ayo akatemerwa OD * madziro ukobvu.Side welding uye kaviri-sided welding spiral welded pombi inofanirwa kuve nechokwadi chekuti hydrostatic bvunzo, kusimba kwekusimba kweiyo weld uye kutonhora kukotama kuita kunodiwa.

(1) the pressure fluid transmission spiral yakanyura arc welded pombi: inonyanya kushandiswa kutakura oiri, gasi rechisikigo pombi;

(2) iyo yekumanikidza fluid transmission yakakwirira frequency welded simbi mapaipi ane spiral musono: welded yakakwirira-frequency lap welding nzira yekumanikidza fluid transmission spiral yakakwirira-frequency welded simbi pombi.Kugona kwesimbi pombi pasi pekumanikidzwa, kunaka kwepurasitiki, kusununguka kwekugadzira uye kuumba nzira;

(3) low pressure fluid transmission spiral undermerged arc welded simbi pombi: kaviri-sided automatic submerged arc welding kana single-sided welding kupinda mumutemo system for low pressure fluid yakadai semvura, gasi, mhepo uye chipfunga chine arc welded pipe.

Seamlesssimbipombi

Seamless pombi chigadzirwa maitiro:
1. isina musono chubhu process performance test: flattening test, tensile test, impact test, flaring test, hardness test, metallographic test, bending test, nondestructive test (kusanganisira eddy current X-ray uye ultrasonic test).

2.Seamless pombi kemikari yekuongorora: iyo kemikari yezvinyorwa zvekuongorora kwemakemikari, kuumbwa kwemakemikari kusangana nezvinodiwa.

3.Seamless pombi pressure uye hydrostatic test ndeyekumanikidza chubhu nekupinda muyero ye hydrostatic, iyo isingachengetedze iyo yakatemerwa kukosha kweiyo isingasviki masekonzi mashanu, kwete kuburitsa, iyo yenguva dzose inopa hydraulic pressure test ndeye 2.45MPa kudzvanywa The pressure test is P = 0.5MPAa.

4.The corrosion test: industrial corrosion-resistant simbi pombi maererano nemitemo yakajairwa kana chibvumirano pakati pekuora kwesimbi pombi corrosion resistance test, hapana intergranular corrosion.

Hunhu hwepaipi isina musono
(1) dhayamita rekunze idiki.

(2) Kunyatsoita zvakanaka kunogona kuita zvimedu zvidiki zvembishi.

(3) inotonhora inodhonzwa simbi pombi ine yakakwirira nemazvo uye yakanaka yepamusoro mhando.

(4) simbi pombi muchinjikwa nzvimbo yakaoma zvikuru.

(5) simbi pombi yepamusoro kuita, yakati dense simbi.
