Ukucaciswa kwepayipi lomugqa: 8-1240×1-200mm

okujwayelekile: API SPEC 5L

Ukusetshenziswa: kusetshenziselwa ukuthutha igesi, amanzi kanye nowoyela ezimbonini ze-petroleum negesi yemvelo.

I-API SPEC 5L-2007 (incazelo yepayipi lomugqa), ehlanganiswe futhi yakhishwa yi-American Petroleum Institute, isetshenziswa kakhulu emhlabeni jikelele.Ipayipi likalayini: Uwoyela, igesi noma amanzi aphuma phansi athuthelwa ezinkampanini zezimboni ze-petroleum negesi yemvelo ngepayipi.Amapayipi olayini ahlanganisa amapayipi angenamthungo namapayipi ashiselwe.Iziphetho zamapayipi zineziphetho eziyisicaba, iziphetho ezinezintambo kanye neziphetho zesokhethi;izindlela zokuxhuma ukuphela kwe-welding, uxhumano lokuhlanganisa, uxhumano lwesokhethi, njll. Izinto eziyinhloko ze-tube yi-B, X42, X46, X56, X65, X70 namanye amamaki ensimbi..

Izinga lepayipi lomugqa:

I-API SPEC 5L-American Petroleum Institute Standard

I-GB/T9711-China National Standard

Sebenzisa:

Amapayipi omoya, amanzi kanye nowoyela asetshenziswa ezimbonini ze-petroleum negesi yemvelo

Ikakhulukazi ukukhiqiza amabanga amapayipi ensimbi:

B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485

Ukubekezelela usayizi wepayipi lomugqa:

1.【Hlukanisa umlilo wamapayipi olayini】Izinga lokushisa eliphansi (150-250 degrees)

Isakhiwo esitholwe ngokushisa okuphansi kwezinga lokushisa yi-martensite epholile.Inhloso yayo ukunciphisa ukucindezeleka kwangaphakathi kanye nokuqina kwensimbi ecishiwe ngaphansi kwesisekelo sokugcina ubulukhuni obuphezulu nokumelana nokugqoka okuphezulu, ukuze ugweme ukuqhekeka noma ukulimala ngaphambi kwesikhathi ngesikhathi sokusetshenziswa.Isetshenziselwa ikakhulukazi amathuluzi okusika ekhabhoni ephezulu, amathuluzi okulinganisa, amapayipi ensimbi e-GB/T9711.1, amabhere aginqikayo kanye nezingxenye ezishisiwe, njll. Ukuqina ngemva kokushisa ngokuvamile ku-HRC58-64.

2.【Hlukanisa umlilo wamapayipi olayini】Izinga lokushisa elimaphakathi (250-500 degrees)

Isakhiwo esitholakala ngokushisa ukushisa okuphakathi yi-troostite epholile.Inhloso ukuthola amandla esivuno esiphezulu, umkhawulo wokunwebeka kanye nokuqina okuphezulu.Ngakho-ke, isetshenziselwa ikakhulukazi ukwelapha amapayipi ensimbi e-GB/T9711.1 ahlukahlukene kanye nesikhunta somsebenzi oshisayo, futhi ubulukhuni ngemva kokushisa ngokuvamile bungu-HRC35-50.

3. 【Hlukanisa umlilo wamapayipi olayini】Izinga lokushisa eliphakeme (500-650 degrees)

Isakhiwo esitholwe ngokushisa okuphezulu kwezinga lokushisa yi-sorbite epholile.Ngokwesiko, ukwelapha okushisa okuhlanganisa ukucisha kanye nokushisa okuphezulu kokushisa kubizwa ngokuthi ukucisha kanye nokwelashwa kokushisa, futhi inhloso yakho ukuthola izakhiwo eziphelele zemishini ngamandla amahle, ubulukhuni, ipulasitiki kanye nokuqina.Ngakho-ke, isetshenziswa kabanzi ezimotweni, amapayipi ensimbi e-GB/T9711.1, amathuluzi omshini nezinye izingxenye ezibalulekile zesakhiwo, njengezinduku zokuxhuma, amabhawodi, amagiya namashafti.Ubulukhuni ngemva kokushisa ngokuvamile buyi-HB200-330.
