1. Isicelo semakethe yamazwe ngamazwe
Amashubhu esilinda sensimbi engenamthungo asetshenziswa kabanzi ekugcineni nasekuthuthweni kwegesi enomfutho ophezulu, futhi izimakethe eziyinhloko zifaka:
Igesi yezimboni (i-oxygen, i-nitrogen, i-argon, njll.):
Izinto: 34CrMo4, 30CrMo (insimbi ye-alloy enamandla aphezulu)
Isicelo: amasilinda egesi anomfutho ophezulu ekukhiqizeni, amakhemikhali, ukushisela kanye neminye imboni.
Igesi yamandla (i-CNG, i-LNG, i-hydrogen):
Izinto: 34CrMo4, XCrMo4 (ukumelana nokucindezela okuphezulu, ukumelana nokushisa okuphansi)
Isicelo: amasilinda e-CNG ezimoto, amathangi okugcina i-LNG, isitoreji samandla e-hydrogen kanye nokuthuthwa.
Igesi yezokwelapha neyezinga lokudla:
Izinto zokwakha: Insimbi engagqwali engu-316L (ukumelana nokugqwala, ukuhlanzeka okuphezulu)
Isicelo: amasilinda e-oxygen yezokwelapha, amasilinda e-CO₂ asezingeni lokudla.
Amasilinda okucisha umlilo kanye nokucwila:
Izinto: 4130, 37Mn (ukuqina okuphezulu, ukumelana nokukhathala)
Isicelo: imishini yokuphefumula umlilo, amasilinda okuntywila.
2. Ukuhlaziywa kwesidingo semakethe
(1) Abashayeli bokukhula kwemakethe yomhlaba wonke
Ukuguqulwa kwamandla: Isidingo esikhulayo samandla ahlanzekile njenge-hydrogen, i-CNG/LNG, njll., siqhuba ukukhula kwemakethe yamasilinda egesi anomfutho ophezulu.
Intuthuko Yezimboni: Isidingo samasilinda egesi anomfutho ophezulu embonini yokukhiqiza, yamakhemikhali, kanye neyezokwelapha sikhule kancane kancane.
Ukuthuthukiswa kwemithethonqubo nezindinganiso: IYurophu ne-United States (DOT, TPED) kanye ne-Asia (GB, JIS) zinezidingo zokuphepha ezengeziwe zamasilinda egesi, okwenze kwaba nesidingo samapayipi angenamthungo asezingeni eliphezulu.
(2) Izici zesidingo semakethe yesifunda
Imakethe yaseYurophu:
Landela ngokuqinile amazinga e-EN 1964 kanye ne-PED (Pressure Equipment Directive), futhi ukhethe izinto ze-34CrMo4 kanye ne-XCrMo4.
Isidingo samandla e-hydrogen kanye namasilinda egesi e-CNG sikhula ngokushesha.
Imakethe yaseNyakatho Melika:
Ngokuyinhloko yamukela indinganiso ye-ASTM A519 (4130/4140), futhi kunesidingo esikhulu samasilinda egesi e-CNG ezimoto.
Imboni kawoyela negesi iqhuba isidingo samasilinda egesi anomfutho ophezulu.
Imakethe yase-Asia (iShayina, iNdiya, iJapan kanye neNingizimu Korea):
IShayina: Izinga elijwayelekile le-GB 18248 liyabusa, ama-34CrMo4, ama-37Mn adingeka kakhulu, kanti imakethe yamasilinda e-CNG/LNG ikhula ngokushesha.
I-India: Izimakethe zegesi yezimboni kanye nezimoto ze-CNG ziyanda, okuqhuba ukungeniswa kwamapayipi esilinda.
| Inkambu yohlelo lokusebenza | Izinto ezivamile | sebenzisa amazinga | Izici |
| Isilinda segesi yezimboni | 34CrMo4、30CrMo | I-ISO 9809, IS 7285 | Amandla aphezulu Ukubekezelela ukucindezela okuphezulu |
| Isilinda segesi se-CNG | 34CrMo4、XCrMo4 | I-EN 1964, ISO 11439 | Ukulwa nokukhathala Ukumelana nokushisa okuphansi |
| Isilinda segesi se-LPG | 37Mn、4130 | IS 7285, DIN 17200 | Uhlobo lwezomnotho Kusebenza ekucindezelweni okuphakathi kanye nokucindezela okuphezulu |
| Isilinda segesi yezokwelapha | 316L, 37Mn | I-ISO 9809-3, IS 8198 | Ayimelani nokugqwala Ukuhlanzeka okuphezulu |
IJapan/South Korea: Insimbi ye-alloy ejwayelekile ye-JIS G3429 (STH11/STH22) efunwa kakhulu.
Imakethe yaseMpumalanga Ephakathi nase-Afrika:
Imboni kawoyela negesi inesidingo esikhulu, kanti imakethe yemishini yokugcina nokuthutha ye-CNG inamandla amakhulu.
Izinzuzo eziyinhloko zamashubhu esilinda sepayipi lensimbi e-China angenamthungo emakethe yamazwe ngamazwe ukusebenza kahle okubiza kakhulu, ukuthobela imithetho ejwayelekile, kanye nochungechunge lokuphakelwa oluzinzile.
Ngokuphathelene neziteshi zokuthenga, inkampani yethu ixhumana ngqo nezimboni zensimbi (njenge-China Baosteel, i-Baotou Steel, i-Hengyang, ne-Tianjin Steel Pipe) ukuze ithole amanani aphansi.
Ukuguquguquka okuphezulu, isevisi yokuma okukodwa yama-oda amancane namakhulu. Kuma-oda amancane, sizobeka phambili ekutholeni indawo yokugcina impahla, futhi kuma-oda amakhulu, sizosebenzisana nemishini yensimbi ukwakha uhlelo lokukhiqiza.
Sihlinzeka ngamanani e-FOB kanye ne-CIF ukusiza amakhasimende ukuxazulula izinkinga zezokuthutha, ukusulwa kwempahla kanye nezinye izinkinga.
I-34CrMo4 kanye ne-37Mn ezikhiqizwa eShayina zishibhile ngo-20%-30% kunemikhiqizo yaseYurophu. Singahlinzeka ngobuningi bama-oda ngokuzinzile. Sineziqu ezivuthiwe kanye namakhono okusebenza ukuze sijwayele futhi sihlinzeke ngezindinganiso. Siphinde sibe nezinkampani ezithutha impahla ezizinzile zesikhathi eside zezinkampani zempahla.
