Heerka: ASTM A500 (ASME SA500)
Ujeedada ugu weyn: koronto, batroolka, shirkadaha kiimikada, heerkulka sare, iska caabinta heerkulka hooseeya, nidaamyada tuubooyinka u adkaysta daxalka.
Alaabooyinka ugu muhiimsan ee heerka birta / birta: Gr.A;Gr.B;Gr.C.
Tilmaamaha: OD: 10.3-820 mm, dhumucda derbiga: 0.8 ilaa 75 mm, Dhererka: 6m, Intaa waxaa dheer, oo ku saleysan shuruudaha macaamiisha, kaas oo bixin kara darajooyin kale iyo qeexitaanno tuubo bir ah.
Processing: birta waa in ay ahaataa mid waafaqsan mid ama in ka badan oo ka mid ah processing: qalbi furan, afuufaya ogsijiin, ama birta foornada korontada, tuurista ee darajooyinka kala duwan ee birta si ay u kala horreeyaan, soo saarayaasha birta waa in ay go'aamiyaan wax dhex dhexaad ah iyadoo la isticmaalayo hababka caadiga ah laga saaray, cad. kala soocidda Heer.
Wax-soo-saarka: waxaa soo saara si aan kala go 'lahayn amaDhuumaha birta welded, tuubooyinka alxanka by giringiriyey sameeyey alxanka caabbinta.Awood qaab dhismeedka qaab dhismeedka jihada dheer ee tuubada, tuubada codsiga xidhidhiyaha waa hab lagu go'aamiyo dhexda dhumucdeeda in la alxanayo.

ASTM A520
ASTM A520 Heerka Gaarka ah ee Shuruudaha Dheeraadka ah ee Alaabada Tubularka Kaarboon-Birta-Kaarboonka-iska-caabbinta-Alxanka-la'aanta ah ee Shuruudaha Dheeraadka ah ee Adeegga Heerkulka Sare ee waafaqsan Talooyinka ISO ee Dhismaha Kuleyliyaha.
Qeexitaanku wuxuu bixiyaa shuruudaha ah in lagu kabo oo laga beddelo shuruudaha ASTM tafatirka alaabada tubaakada kaarboon-kaarboonka-iska-caabbinta-la'aanta iyo korantada ee ku habboon adeegga heerkulka sare, marka alaabooyinkan tuubada ah loo adeegsado codsiyada u hoggaansamaya Xeerarka ISO.Tilmaamaha tubbada ee laga yaabo in ay tilmaamaan waxa ka mid ah: Dhuumaha Birta Kaarboon-kaarboonka ee Adeegga Heerkulka Sare A106 Tuubooyinka Kaarboon-Kaarboon-iska-caabbinta-Alxanka Tubooyinka A178/A 178M Kuleyliyaha Birta Kaarboon Dhexdhexaadka ah iyo Tubooyinka Kululiyaha A 210/A 210M Kuleyliyaha-Kaarboon-Kaarboonka-iska-caabbinta-Alxanka iyo 226 Tubooyinka Kuleyliyaha Sare ee Adeegga Cadaadis Sare.Qiimaha lagu sheegay halbeeg-rodol waa in loo tixgaliyaa heerka caadiga ah.
