Umgangatho: ASTM A500 (ASME SA500)
Injongo ephambili: umbane, i-petroleum, iinkampani zeekhemikhali, ubushushu obuphezulu, ukuxhathisa ubushushu obuphantsi, iinkqubo zemibhobho ekwazi ukumelana nomhlwa.
Iimveliso eziphambili zentsimbi / ibakala lensimbi: Gr.A;Ibakala B;Gr.C.
Iinkcukacha: OD : 10.3-820 mm, ubukhulu bodonga: 0.8 ukuya ku-75 mm, Ubude: 6m, Ukongezelela, ngokusekelwe kwiimfuno zabathengi, ezinokubonelela ngamanye amabakala kunye neenkcukacha zepayipi yensimbi.
Ukucutshungulwa: insimbi iya kuhambelana nenye okanye ngaphezulu kokucutshungulwa: i-open-hearth, i-oxygen evuthelayo, okanye i-steelmaking yesithando sombane, ukuphosa amabakala ahlukeneyo ensimbi ngokulandelelana, abavelisi bensimbi kufuneka banqume izinto eziphakathi usebenzisa iinkqubo eziqhelekileyo ezisusiweyo, ezicacileyo. ukwahlukana kweNqanaba.
Manufacturing: iveliswa ngokungenamthungo okanyeumbhobho wentsimbi odityanisiweyo, umbhobho odityanisiweyo ngokuqengqeleka owenziwe ngokumelana ne-welding.Amandla oyilo lolwakhiwo lwecala longitudinal lombhobho, ityhubhu yesicelo sedocking yindlela yokumisela ngokutyeba kwayo ukuwelda.

I-ASTM A520
Inkcazo yoMgangatho we-ASTM A520 yeeMfuno ezoNgezelelweyo zoMthungo kunye ne-Electric-Resistance-Welded Carbon Steel Tubular Products kwi-High-Temperature Service ehambelana neeNgcebiso ze-ISO kuLwakhiwo lweBoiler.
Le ngcaciso ibonelela ngeemfuno eziya kuncedisa kwaye zigqithise iimfuno ze-ASTM zenkcazo ezingenamthungo kunye ne-electric-resistance-welded carbon steel tubular iimveliso ezifanelekileyo kwinkonzo yobushushu obuphezulu, xa ezi mveliso ze-tubula ziza kusetyenziswa kwizicelo ezihambelana nemithetho ye-ISO.Iinkcukacha zetyhubhu ezinokuthi zibhengeze olu balulo zezi: Umbhobho weNtsimbi weKhabhoni ongenaMthungo weNkonzo yoBubushushu obuPhezulu A 106 uMbane-Ukumelana-Welded iCarbon Steel Boiler Tubes A 178/A 178M iSeamless Carbon Steel Boiler Tubes for High-Pressure Service A 192M 192M 192M Ibhoyila yentsimbi yeCarbon engenamthungo ePhakathi kunye neeThubhu ze-Superheater ye-A 210/A 210M yoMbane-Ukumelana-iWelded iBoiler yentsimbi yeCarbon kunye ne-226 ye-Superheater Tubes yeNkonzo yoxinzelelo oluphezulu.Amaxabiso achazwe kwiiyunithi ze-inch-pound kufuneka athathwe njengomgangatho.
