2. Tlhahlobo ea tlhoko ea 'maraka
(1) Bahlohlelletsi ba kholo ea 'maraka oa lefats'e
Phetoho ea eneji: Tlhoko e ntseng e eketseha ea eneji e hloekileng joalo ka haedrojene, CNG/LNG, jj., e khanna kholo ea 'maraka oa silindara ea khase e nang le khatello e phahameng.
Ntshetsopele ea indasteri: Tlhoko ea lisilindara tsa khase tse nang le khatello e phahameng indastering ea tlhahiso, lik'hemik'hale le bongaka e ntse e hola butle-butle.
Ntlafatso ea melaoana le maemo: Europe le United States (DOT, TPED) le Asia (GB, JIS) li na le litlhoko tse eketsehileng tsa polokeho bakeng sa lisilindara tsa khase, e leng se susumetsang tlhoko ea liphaephe tse se nang sekoli tsa boleng bo holimo.

'Maraka oa Europe:
Latela ka tieo maemo a EN 1964 le PED (Pressure Equipment Directive), 'me u khethe lisebelisoa tsa 34CrMo4 le XCrMo4.
Tlhoko ea matla a haeterojene le lisilindara tsa khase tsa CNG e ntse e hola ka potlako.
'Maraka oa Amerika Leboea:
Haholo-holo e amohela maemo a ASTM A519 (4130/4140), 'me ho na le tlhoko e kholo ea lisilindara tsa khase tsa CNG tsa likoloi.
Indasteri ea oli le khase e susumetsa tlhoko ea lisilindara tsa khase tse nang le khatello e phahameng.
'Maraka oa Asia (Chaena, India, Japane le Korea Boroa):
Chaena: Maemo a tloaelehileng a GB 18248 aa busa, 34CrMo4, 37Mn li batloa haholo, 'me' maraka oa lisilindara tsa CNG/LNG o ntse o hola ka potlako.
India: Mebaraka ea khase ea indasteri le likoloi tsa CNG e ntse e atoloha, e leng se etsang hore lipeipi tsa lisilindara li kenngoe ka ntle.

'Maraka oa Bochabela bo Hare le Afrika:
Indasteri ea oli le khase e na le tlhoko e kholo, 'me' maraka oa polokelo le lisebelisoa tsa lipalangoang tsa CNG o na le bokhoni bo phahameng.
Melemo ea mantlha ea lipeipi tsa silindara tsa tšepe tse se nang sekoli tsa Chaena 'marakeng oa machaba ke ts'ebetso e theko e phahameng, ho latela melao e tloaelehileng, le ketane ea phepelo e tsitsitseng.
Mabapi le metjha ya ho reka, khamphani ya rona e hokahana ka ho toba le difeme tsa tshepe (tse kang China Baosteel, Baotou Steel, Hengyang, Tianjin Steel Pipe) ho fumana ditheko tse tlase.
Ho tenyetseha ho hoholo, tšebeletso ea ho emisa ntho e le 'ngoe bakeng sa liodara tse nyane le tse kholo. Bakeng sa liodara tse nyane, re tla etelletsa pele ho fumana sebaka sa polokelo, 'me bakeng sa liodara tse kholo, re tla sebetsa le lifeme tsa tšepe ho theha kemiso ea tlhahiso.
