Uma ufuna ukwazi ulwazi olwengeziwe, njengekhotheshini, imikhiqizo, izixazululo, njll., pqashaxhumana nathi ku-inthanethi.
I-Tianjin Sanon Steel Pipe Co., Ltd. ingumthengisi wamasheya. Ifektri yethu yamasheya iseDolobheni laseCangzhou, eSifundazweni saseHebei. Imithombo yethu eyinhloko yezimpahlaamapayipi ebhoyila, futhi izinto ezimele ziyiI-ASTM A335 P5/P11/P91/P92,I-ASME SA-106/SA-106MGR.B,I-GB/T 3087-200810#/20#. Izinto ezimele amapayipi epayipi yileziI-API 5L,I-API 5CT, izinto ezimele amapayipi okuqhekeka kwephethiloliI-GB/T 9948ziyi-15MoG/12CrMoVG. I-GB/T 6479-2013 imele izinto ezingu-10#/20#, amashubhu okushintshanisa ukushisa i-SA179/SA210/SA192, njll., amashubhu omshini i-GB/T 8162 amele izinto ezingu-10#/20#/Q345/42CrMo, i-EN10210 imele izinto ezingu-S355JOH/S355J2H, amashubhu esilinda segesi i-GB1 8248, amele izinto ezingu-34CrMo4/30CrMo.
Ukuthengwa kwepayipi lensimbi yekhabhoni kanye nesilinganiso
Ipayipi lensimbi yekhabhoni liwumkhiqizo ovame ukusetshenziswa kakhulu oboniswa futhi uthengwe amakhasimende. Imininingwane evamile ifaka phakathiI-ASTM A106 GRB, ububanzi bangaphandle bungu-60-273mm, ubukhulu bodonga bungu-SCH40-SCH80. Ngaphambi kokuthenga, kubalulekile ukuhlunga imininingwane yezidingo zamakhasimende bese ucela abahlinzeki ngamanani. Abahlinzeki bekhwalithi ephezulu esibambisana nabo bahlanganisa iBaosteel, iHengyang, iTPCO, i-Anhui Tianda, iLuli, iFengbao, njll., futhi sibeka kuqala izinto ezitholakala endaweni yazo ukuqinisekisa impendulo esheshayo ezidingweni zamakhasimende.
Uma umhlinzeki enikeza intengo yepayipi elingenalutho, kudingeka ukucubungula okwengeziwe, okubandakanya ukuthutha impahla, izimali zokucubungula kanye nemali yokuhlola (ngokuya ngezidingo zamakhasimende). Ukuhlolwa okuyisisekelo kufaka phakathi ububanzi bangaphandle, ukujiya kodonga, ukulinganiswa kobude, kanye nokuqinisekiswa kwesithombe noma ividiyo. Ukuhlolwa komuntu wesithathu kungahlelwa ngokubambisana, futhi zonke izithombe zepayipi lensimbi zigcinwa ukuze zibhekwe.
Ukuthengwa kwamapayipi ensimbi ye-alloy kanye nezici
Inqubo yokuthengwa kwamapayipi ensimbi e-alloy ifana neyamapayipi ensimbi e-carbon, kodwa ukusebenza kwezinto kuhluke kakhulu. Insimbi e-carbon yakhiwe kakhulu ngensimbi ne-carbon, ngezindleko eziphansi futhi ifanele ukukhiqizwa ngobuningi, kodwa ayinabo ukuqina futhi ithambekele ekuqhekekeni okuqhekekayo emazingeni okushisa aphansi. Insimbi e-alloy yengeza izinto ezifana ne-chromium, i-nickel, ne-molybdenum ukuthuthukisa ukumelana nokugqwala, amandla okushisa aphezulu, kanye nokumelana nokuguguleka. Isibonelo:
I-ASTM A335 P5, P9, P11, P22,I-P91
I-GB/T 5310 12Cr1MoVG, 15CrMoG
Ipayipi lesilinda segesiGB/T 18248-2021 34CrMo4, 37Mn
Sinezimbobo ze-alloy ezingamathani angu-20,000 ezikhona unyaka wonke ukuze kuhlangatshezwane nezidingo ezahlukahlukene.
Amaphuzu abalulekile okuthengaamapayipi kawoyelafuthiamapayipi
Amapayipi kawoyela namapayipi asetshenziswa kakhulu kuma-oda obunjiniyela noma ukugcwalisa kabusha. Amathani amancane ayathandwa uma kuthengwa khona manjalo, kanti ama-oda amakhulu adinga ukubuyekezwa nokuhlela. Ama-oda obunjiniyela avame ukucacisa izinhlobo kanye nezidingo zokubhida. Singahlinzeka ngemibhalo yokufaneleka ukusekela ukubhida. Amacala aphumelelayo ahlanganisa i-India, iNepal, iVietnam, iBahrain, iPeru, iNigeria namanye amazwe, anolwazi oluvuthiwe ekusebenzeni kwama-oda obunjiniyela.
Isifinyezo
Ukuthengwa kwamapayipi ensimbi angenamthungo kudinga ukuhambisana kahle nezidingo zamakhasimende. Amapayipi ensimbi yekhabhoni, amapayipi e-alloy, amapayipi kawoyela kanye namapayipi omugqa ngalinye linezici zalo. Sithembele kubaphakeli bekhwalithi ephezulu kanye nempahla eningi ukuqinisekisa ukulethwa okuphumelelayo, ngenkathi sisekela izinsizakalo zokucubungula nokuhlola ezenziwe ngokwezifiso ukuze sinikeze izixazululo zamapayipi ensimbi ezinokwethenjelwa zamaphrojekthi omhlaba wonke.
