Ntchito M'minda mwa Makinawa kuwotcherera

 CNPC

     Ndikukula kwachuma, anthu amadalira kwambiri mphamvu. Kuyendetsa mapaipi ndi njira yofunikira poyendetsera mphamvu. Ndizotetezeka komanso ndizochuma motero zakhala zikugwiritsidwa ntchito kwambiri. Makina owotcherera atha kugwiritsidwa ntchito popanga ma payipi m'mafakitale osiyanasiyana monga mafuta, gasi, mafakitale, ma hydropower station, tank thupi, zomangamanga zam'madzi, madzi ndi ukadaulo wa ngalande, ukadaulo wamafuta ndi zina zambiri. Pakati pa madera ambiri omwe akugwiritsidwa ntchito, payipi yofunika kwambiri yopatsira mafuta ndi gasi mosakayikira. Chifukwa chake, zida zabwino zodziwikiratu ziyenera kukhazikitsidwa ngati zingasinthidwe bwino kuti zikwaniritse mapaipi amafuta ndi gasi ngati muyeso wodziyesa.

     Ndi kugwiritsa ntchito ndi kupititsa patsogolo kwa mapaipi kuwotcherera kwamafuta ndi mapaipi amafuta achilengedwe, ndipo nthawi yomweyo, mapaipi akumanga ali ndi zofunikira kwambiri pakulimbikira kokometsera, kumakhala kovuta kwambiri kuphunzitsa ma welders achikhalidwe. Mapaipi kuwotcherera zodziwikiratu kumachepetsa kuwonjezeka kwa ntchito kwa ma welders ndikugwiritsa ntchito nthawi ya ma welders. Mwachidule, njira yapa-site yodziwikiratu imagwiridwa bwino, ndipo magwiridwe antchito a kuwotcherera ndiabwino. China ndi dziko lomwe lili ndi malo ovuta kwambiri. Mizinda yambiri yomwe ili ndi anthu ambiri ili m'mapiri akumwera ndi mapiri ndi madera amadzi, ndipo pakufunikanso kwambiri mayendedwe amapaipi achilengedwe. Pali zambiri, kotero zida zodziwikiratu za chitoliro zoyenera malo ovuta ndizofunikira kwambiri.

     Kuphatikiza mawonekedwe a phiri lalikulu lotsetsereka, gawo lamadzi ndi malo osungira malo okhala ndi malo oletsedwa ogwirira ntchito, Tianjin Yixin amaphatikizira makina onse otchingira okha, ndikuwongolera kakulidwe kakang'ono, ntchito yamphamvu kwambiri, ndi kuwotcherera kolimba kwambiri . Njira yothetsera zida ikukwaniritsa zosowa za mapaipi owotcherera m'malo opangira zovuta.

     Posachedwa, ndinayang'ana lipoti lofufuzira za ngozi yomwe yaphulika payipi yaphulika m'dera la Shazi Town ku Qinglong County, Qinglong County, Qianxinan Prefecture la payipi ya gasi lachilengedwe la China-Myanmar pa Juni 10, 2018. Ngoziyi idapangitsa kufa kwa 1 ndi kuvulala kwa 23, ndi kutaya kwachuma kwachindunji kwa yuan miliyoni 21.45.

     Ngoziyi idachitika chifukwa chophwanyika kwa girth weld, komwe kudapangitsa kuti gasi wambiri payipi atayike ndikusakanikirana ndi mpweya kuti apange chisakanizo chophulika. Kusamvana kwakukulu pakati pa kuchuluka kwa mpweya wachilengedwe ndi kuphulika kwa chitoliro kunayambitsa magetsi kuti ayambe kuyaka ndikuphulika. Choyipa chachikulu cha ngoziyi ndikuti mtundu wazowotcherera pamalowo sizinakwaniritse zofunikira, zomwe zidapangitsa kuti chimbudzi cha girth chiphwanyeke pansi pa katundu wophatikizika. Zinthu zomwe zimayambitsa mavuto ndi mtundu wa ma girth welds ndizophatikizira njira zowotchera mapaipi a X80 pamalopo, zofunikira zochepa pamayeso osawononga pamalopo, komanso kusamalira bwino ntchito yomanga. Kutsekemera kwa theka-automatic + kuwotcherera pamanja kumagwiritsidwa ntchito potulutsa mapaipi amafuta achilengedwe pamzere wa China-Myanmar. Omwe amawotcherera omwe amagwiritsidwa ntchito ndi omwe adachita kuwotchera mwangozi apanga ziphaso zogwiritsa ntchito zida zapadera. Zomwe zimayambitsa ngoziyi ndizodabwitsa.

     Maipi otsekemera nthawi zambiri amagwiritsa ntchito kutuluka kwakukulu, kudzaza ndikutsekemera kumamalizidwa mosavuta, zomwe zimatsimikizira kuti kuwotcherera kumakhala kofanana poyerekeza ndi bukuli, potero kuwonetsetsa kuti weld ikuyenda bwino, ndikupereka chitsimikizo chofunikira chachitetezo cha nthawi yayitali ntchito ya payipi.
