2. Uhlalutyo lwemfuno yemarike
(1) Izinto ezibangela ukukhula kwemarike kwihlabathi liphela
Utshintsho lwamandla: Ukunyuka kwemfuno yamandla acocekileyo afana ne-hydrogen, i-CNG/LNG, njl.njl., kuqhuba ukukhula kwemarike yesilinda yegesi enoxinzelelo oluphezulu.
Uphuhliso lwemizi-mveliso: Imfuno yeesilinda zegesi ezinoxinzelelo oluphezulu kumashishini okuvelisa, amachiza, kunye namayeza ikhule ngokuthe chu.
Ukuphuculwa kwemigaqo nemigangatho: IYurophu neMelika (DOT, TPED) kunye neAsia (GB, JIS) zinemfuno yokhuseleko oluphezulu kwiisilinda zegesi, nto leyo eqhubela phambili imfuno yeepayipi ezingenamthungo ezikumgangatho ophezulu.
(2) Iimpawu zemfuno yemarike yengingqi
Imakethi yaseYurophu:
Landela ngokungqongqo imigangatho ye-EN 1964 kunye ne-PED (Pressure Equipment Directive), kwaye ukhethe izinto ze-34CrMo4 kunye ne-XCrMo4.
Imfuno yamandla e-hydrogen kunye neesilinda zegesi ze-CNG ikhula ngokukhawuleza.
Imakethi yaseMntla Melika:
Ngokuyintloko yamkela umgangatho we-ASTM A519 (4130/4140), kwaye kukho imfuneko enkulu yeesilinda zegesi ze-CNG zeemoto.
Ishishini leoyile negesi liqhuba imfuno yeesilinda zegesi ezinoxinzelelo oluphezulu.
Imakethi yaseAsia (iTshayina, iIndiya, iJapan kunye neSouth Korea):
ITshayina: Umgangatho we-GB 18248 uyalawula, i-34CrMo4, i-37Mn zifunwa kakhulu, kwaye imakethi yesilinda ye-CNG/LNG ikhula ngokukhawuleza.
I-Indiya: Iimarike zegesi yemizi-mveliso kunye neemoto ze-CNG ziyanda, nto leyo ebangela ukuba kuthengwe iityhubhu zesilinda kwamanye amazwe.
| Intsimi yesicelo | Izixhobo eziqhelekileyo | nyanzelisa imigangatho | Iimpawu |
| Isilinda segesi yemizi-mveliso | 34CrMo4、30CrMo | I-ISO 9809, IS 7285 | Amandla aphezulu Melana noxinzelelo oluphezulu |
| Isilinda segesi se-CNG | 34CrMo4, XCrMo4 | EN 1964, ISO 11439 | Ukulwa nokudinwa Ukumelana nobushushu obuphantsi |
| Isilinda segesi ye-LPG | 37Mn、4130 | IS 7285, DIN 17200 | Uhlobo lwezoqoqosho Isebenza kuxinzelelo oluphakathi noluphezulu |
| Isilinda segesi yezonyango | 316L, 37Mn | I-ISO 9809-3, IS 8198 | Ayikwazi ukugqwala Ucoceko oluphezulu |
IJapan/eMzantsi Korea: I-JIS G3429 (STH11/STH22) intsimbi ye-alloy esemgangathweni, ekumgangatho ophezulu ifunwa kakhulu.
Imakethi yaseMbindi Mpuma naseAfrika:
Ishishini leoyile negesi lifunwa kakhulu, kwaye imakethi yezixhobo zokugcina nezokuthutha ze-CNG inamandla aphezulu.
Iingenelo eziphambili zeetyhubhu zesilinda zentsimbi ezingenamthungo zaseTshayina kwimarike yamazwe ngamazwe kukusebenza ngexabiso eliphezulu, ukuthobela imithetho esemgangathweni, kunye nothungelwano lokubonelela oluzinzileyo.
Ngokuphathelele iindlela zokuthenga, inkampani yethu iqhagamshelana ngokuthe ngqo neefektri zentsimbi (ezifana neChina Baosteel, iBaotou Steel, iHengyang, neTianjin Steel Pipe) ukuze ifumane amaxabiso aphantsi.
Ukuguquguquka okuphezulu, inkonzo yokumisa indawo enye kwiiodolo ezincinci nezinkulu. Kwiiodolo ezincinci, siza kunika ingqalelo ekufumaneni indawo yokugcina izinto, kwaye kwiiodolo ezinkulu, siza kusebenza neefektri zentsimbi ukwenza ucwangciso lwemveliso.
Sibonelela ngamaxabiso e-FOB kunye ne-CIF ukunceda abathengi basombulule iingxaki zezothutho, ukususwa kwerhafu kunye neminye imiba.
I-34CrMo4 kunye ne-37Mn eziveliswa eTshayina zitshiphu nge-20%-30% kuneemveliso zaseYurophu. Singabonelela ngobuninzi beeodolo ngokuzinzileyo. Sineziqinisekiso ezivuthiweyo kunye nezakhono zokusebenza zokuqhelana nokubonelela ngemigangatho. Sikwanazo neenkampani zokuhambisa imithwalo ezizinzileyo zexesha elide.
