STPG 370 waa darajada tuubooyinka birta ee kaarboon-yar oo lagu qeexay heerka Japan JIS G 3454.
STPG 370 waxa uu leeyahay ugu yaraan cudud xawli ah oo ah 370 MPa iyo awoodda wax-soosaarka ugu yar ee 215 MPa.
STPG 370 waxaa loo soo saari karaa sida tuubooyinka birta ah ee aan fiicnayn ama tuubooyinka birta welded iyadoo la adeegsanayo habka alxanka caabbinta korantada (ERW).Waxay ku habboon tahay in loo isticmaalo hababka tuubbooyinka cadaadiska leh heerkulka shaqaynta ilaa 350 ° C.
Marka xigta, waxaan eegi doonaa STPG 370 ee hababka wax soo saarka, halabuurka kiimikada, sifooyinka farsamada, tijaabooyinka cadaadiska hydrostatic, baaritaanka aan burburin, iyo daahan galvanized.
JIS G 3454 STPG 370 waxaa lagu soo saari karaa iyadoo la isticmaalayoaan kala go 'lahayn or ERWhabka wax soo saarka, oo ay weheliyaan hababka dhamaystirka habboon.

STPG 370 waa bir kaarboon-yar marka loo eego ka koobnaanta kiimikada.Halabuurka kiimikaad waxaa loogu talagalay in lagu isticmaalo meelo aan ka badnayn 350 ° C, oo leh xoog wanaagsan, adag, iyo iska caabin heerkul sare ah.

Marka lagu daro xoogga jilicsanaanta, xoogga jilicsanaanta, iyo dhererka aan kor ku soo sheegnay, waxaa sidoo kale jira tijaabin fidsan iyo leexin.
Tijaabada fidsan: Marka masaafada u dhexeysa labada taarikada ay gaarto masaafada la cayimay H, waa in aysan jirin cillado ama dildilaaca dusha sare ee tuubada birta.
Dabacsanaanta: Tuubbadu waa in la laalaa 90° xagal 6 jeer dhexroorkeeda dibadda ah.Darbiga tuubbadu waa inuu ahaadaa mid ka nadiif ah cillado ama dildilaac.
Tuub kasta oo bir ah waxaa lagu sameeyaa tijaabo hydrostatic ama baaritaan aan burburin si loo hubiyo wixii cillado ah ee aan indhaha qaawan arkin.
Baaritaanka Hydrostatic
Marka loo eego darajada la qorsheeyay ee dhumucda gidaarka tuubada birta, dooro qiimaha cadaadiska biyaha ee ku habboon, ku hay ugu yaraan 5 ilbiriqsi, oo hubi in tuubada birta ay soo daadanayso.

Tijaabada aan burburin
Haddii baaritaanka ultrasonic la isticmaalo, waa in lagu saleeyaa heer ka adag kan calaamada fasalka UD ee JIS G 0582.
Haddii tijaabada hadda jirta la isticmaalo, waa in lagu saleeyaa halbeeg ka adag calaamadda fasalka EY ee JIS G 0583.
JIS G 3454, tuubooyinka birta ah ee aan dahaarka lahayn ayaa loo yaqaantubooyinka madowiyo tubooyinka birta galvanized ayaa loo yaqaantubooyinka cadcad.
Dhuumaha cad: Dhuumaha birta galvanized
Dhuumaha madow: tuubo bir ah oo aan galvanized ahayn
Habka tuubooyinka cad cad ayaa ah in tuubooyinka madow ee aqoonta leh la toogto ama la soo qaado si wasakhda looga saaro dusha tuubada birta ka dibna lagu galvanized Zinc oo buuxiya heerka JIS H 2107 ee ugu yaraan fasalka 1. Arrimaha kale ayaa la fuliyay. iyadoo la raacayo heerka JIS H 8641.
Tilmaamaha dahaarka zinc waxaa lagu hubiyaa si waafaqsan shuruudaha JIS H 0401, Qodobka 6.
Tan iyo markii la aasaasay 2014,Botop Steelwaxay noqotay shirkad hormuud u ah tuubbooyinka birta kaarboon ee Waqooyiga Shiinaha, oo caan ku ah adeeg aad u wanaagsan, alaab tayo sare leh, iyo xalal dhammaystiran.
Shirkaddu waxay bixisaa noocyo kala duwan oo ah tuubooyinka birta kaarboonka iyo alaabada la xidhiidha, oo ay ku jiraan kuwa aan fiicneyn, ERW, LSAW, iyo tuubada birta ee SSAW, iyo sidoo kale saf buuxa oo ah xirmooyinka tuubooyinka iyo flanges.Alaabooyinkeeda gaarka ah waxa kale oo ka mid ah alloys-ga sare iyo biraha austenitic ahama, oo loogu talagalay in lagu daboolo baahiyaha mashaariicda dhuumaha ee kala duwan.
