Ukuba ufuna ukwazi ulwazi oluthe kratya, olufana neekowuteshini, iimveliso, izisombululo, njl.njl., pqeshisanxibelelana nathi kwi-intanethi.
I-Tianjin Sanon Steel Pipe Co., Ltd. ngumthengisi wempahla. Ifektri yethu yempahla ikwiSixeko saseCangzhou, kwiPhondo laseHebei. Imithombo yethu ephambili yeempahla yileimibhobho yebhoyila, kwaye izixhobo ezimeleyoI-ASTM A335 P5/P11/P91/P92,I-ASME SA-106/SA-106MGR.B,GB/T 3087-200810#/20#. Izinto ezimele imibhobho yepayipi zeziI-API 5L,I-API 5CT, izinto ezimele imibhobho yokuqhekeka kwepetroliyamI-GB/T 9948ziyi-15MoG/12CrMoVG. I-GB/T 6479-2013 imele izinto ezi-10#/20#, iityhubhu zokutshintsha ubushushu i-SA179/SA210/SA192, njl.njl., iityhubhu zoomatshini i-GB/T 8162 zimele izinto ezi-10#/20#/Q345/42CrMo, i-EN10210 imele izinto ezi-S355JOH/S355J2H, iityhubhu zesilinda yegesi i-GB1 8248, zimele izinto ezi-34CrMo4/30CrMo.
Okokuqala, ioyile negesi. Le yeyona marike inkulu yeepayipi zentsimbi ezingenamthungo. Umgangatho we-casing, iityhubhu kunye neepayipi zokubhola ezisetyenziswa kwindawo evulekileyo ephezulu nguloI-API 5CT, kwaye izixhobo ziqukaJ55, K55, L80kunye ne-P110. Iipayipi zemibhobho zemibhobho emide esezantsi, eqhelekileyoI-API 5LizintoX42 to X80Ngowama-2025, umlinganiselo weepayipi zentsimbi ezingenamthungo zaseTshayina ezithunyelwa kuMbindi Mpuma uza kuba yi-42%, kwaye yiloo nto uninzi.
Okwesibini, izityalo zokucoca kunye neekhemikhali kunye nezikhululo zamandla. Imibhobho yentsimbi engatyiwayo kunye nentsimbi ye-alloy yokucokisa kunye nezityalo zeekhemikhali, iityhubhu zebhoyila ezinoxinzelelo oluphezulu zeebhoyila zezikhululo zamandla, ezifana ne-P91 kunye ne-P92. Imigangatho eqhelekileyo: GB 5310,I-ASTM A335, I-ASTM A213Izinto: 15CrMoG, 12Cr1MoVG, kunyeP11, P22, I-P91, I-P92Nangona imakethi yaseYurophu ibandakanya inxalenye encinci kuphela yokuthunyelwa kweepayipi ezingenamthungo, uninzi lwazo ziimveliso ezinexabiso eliphezulu.
Okwesithathu, uyilo lwezakhiwo, imisebenzi kamasipala, kunye neendlela kunye neeBhulorho. Kukho imfuno enkulu yeepayipi ezidityanisiweyo kweli candelo. Imigangatho eqhelekileyo: GB/T 3091, ASTM A53, EN 10219. Izinto eziphambili yintsimbi yekhabhoni i-Q235B kunye ne-Q355B. Amazwe akwiBelt and Road Initiative anemfuno enkulu yeziseko zophuhliso, kwaye ukuthunyelwa kwamanye amazwe kweepayipi ezidityanisiweyo kunyuke kakhulu kwiminyaka yakutshanje.
Okwesine, ukwenziwa koomatshini. Iityhubhu ezithambileyo nezithambileyo ezitsalwa ngokucokisekileyo zisetyenziswa kwiibharele ze-hydraulic cylinder, ii-drive shafts kunye nee-shock absorbers. Imigangatho: GB/T 3639, EN 10305-1, ASTM A519. Izinto: 20#, 45#, 40Cr, 35CrMo. Ukongeza, icandelo elitsha lamandla nalo liyakhula: ii-wind power towers, ii-photovoltaic brackets, kunye nee-hydrogen gas cylinders zonke zisebenzisa iipayipi zentsimbi.
Ezi ngongoma zingentla zezona ndawo ziphambili zokuthunyelwa kweepayipi zentsimbi kwimarike yamazwe ngamazwe. Kwiphepha elilandelayo, ndiza kwabelana nani ngee-terminals eziphambili zamazwe ngamazwe kwisicelo ngasinye, ndibeka umkhombandlela ocacileyo worhwebo lwethu lwangaphandle lweepayipi zentsimbi.
