Ku saabsanQalabka tuubooyinka ASTM A234 WPB
ASTM A234 waa qeexida caadiga ah ee xirmooyinka tuubooyinka birta waxaa ku jira kaarboon iyo walxo bir ah oo loogu talagalay adeegyada heerkulka dhexdhexaadka ah iyo sare.Waxay dabooshaa qalabyada birta ah ee noocyada alxanka leh.Qalabka birta ah ee tuubooyinka waxaa lagu dabaqaa dhuumaha cadaadiska iyo maraakiibta cadaadiska.Walxahaan ku rakiban waxay ka kooban yihiin bir la dilay, foorjaro, baararka, taargooyinka, bilaa-la'aanta ama HFW (fiyuuska alxanka) alaabta tuubooyinka, oo lagu daray biraha buuxinta.
Waa maxay WPB?
W = WELDABLE / la sameeyay
P = LAXIRIIRTA T TIRADA ALLOOY ALAAB AH
B = TIXRAAC SAARAHA UGU YAR EE ALAABTA
Waxay ku jiraan dib u eegistii ugu dambeysay ee ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, iyo MSS-SP-97.Sidoo kale si weyn loogu isticmaalo tuubooyinka cadaadiska iyo samaynta weelka cadaadiska ee adeega heerkulka dhexdhexaadka ah iyo sare.Dhibcuhu waa ASTM A234 WPB, WPC, WP5, WP9, WP91, WP11, WP12 iyo WP22.

Farqiga u dhexeeya A105 iyo A234
ASTM A234 WPB Xirmooyinka tuubooyinka waxay ka samaysan yihiin bir kaarboon ah oo la sameeyay oo aad u xoog badan oo lagu dabaqi karo shuruudaha xoogga sare.ASTM A234 WPB waxaa lagu daaweeyaa kulayl ka dibna loo oggolaado inay si degdeg ah u qaboojiso.
Qalabyada Birta Kaarboon ee Been Abuurka ah waa tuubooyin ka samaysan A105 Material.Kuwaas waxaa lagu soo saaraa xaalad la koolkooliyey, mid caadi ah, caadi ah oo la xanaaqay ama la demiyey oo la xanaaqay.
