Waxaa si toos ah u shaqeeya soosaarayaasha tuubooyinka birta ee wareega ee goobaha dhismaha
Heerarka caadiga ah ee dhuumaha birta wareega ah ayaa guud ahaan loo qaybiyaa: SY / t5037-2008 (Heerka wasaaradda, sidoo kale loo yaqaan spiral submerged arc welded tube steel ee dhuumaha gudbinta dareeraha caadiga ah), GB / t9711.1-2008 (heer qaran, sidoo kale loo yaqaan Sida shuruudaha bixinta farsamada ee gudbinta birta birta ee saliidda iyo warshadaha gaaska, qaybta I: fasalka birta birta ah (GB / t9711.2 fasalka B tuubo bir ah oo leh shuruudo adag)), api-5l (Ururka Batroolka Mareykanka, oo sidoo kale loo yaqaano birta dhuumaha tuubo); Oo ay ku jiraan PSL1 iyo PSL2), SY / t5040-2008 (tuubyada birta alxanka leh ee tuulan).
SY / t5037-2008 waa halbeega ay dejisay Wasaaradda Batroolka, kaasoo guud ahaan loo yaqaan heerka wasaaradda.
GB / t9711.1-2008 dhuumaha wareega qaranka, birta gudbinta ee batroolka iyo warshadaha gaaska dabiiciga ah, fasalka A.
Spiral seam-sare-soo noqnoqoshada tubbada birta alxanka ah (sy5039-2000) ee gaadiidka dareere cadaadiska hoose ee guud wuxuu qaataa gariiradda birta kulul duuban ee kulul sida tuubbada maran, inta badan diiran samaynta, oo adeegsada habka alxanka dhabta-soo noqnoqda sare si ay u alxanka tollayn sare sare- inta jeer ee tuubooyinka birta alxanka leh ee gaadiidka dareeraha cadaadiska hooseeya.
Tuubooyin bir ah oo isbiirsaday oo tuulan (sy5040-2000) waxay ka samaysan tahay gariiradda birta duuban ee kulul sida tuubbada bannaan, badiyaa diirran samaynta, alxanka arc laba-geesoodka ah ama alxanka-soo noqnoqda sare leh. Waxaa loo isticmaalaa tuubooyinka birta ee gundhigga dhismaha dhismaha madaniga ah, wharf, buundada iyo wixii la mid ah. Gaadiidka dareeraha la cadaadiyay, spiral submerged arc welded tube steel sy5036-2000 ayaa loo isticmaalaa, taas oo inta badan loo isticmaalo dhuumaha qaada saliidda iyo gaaska dabiiciga ah;
Spiral seam-sare-soo noqnoqoshada alxanka tuubada birta sy5038-2000 ee gudbinta dareeraha cadaadiska, kaas oo lagu alxanayo by habka alxanka-soo noqnoqda dhabta ah oo loo isticmaalo gudbinta dheecaan cadaadis. Tuubada birta ahi waxay leedahay awood cadaadis xoog leh iyo caag wanaagsan, taas oo ku habboon alxanka iyo farsamaynta;
Gaadiidka dareeraha guud ee cadaadiska hooseeya, spiral seam submerged arc welded tube steel sy5037-2000 ayaa loo isticmaalaa, iyo dhuumaha birta ah ee arc alxanka hoostiisa ee gaadiidka dareeraha cadaadiska hoose ee guud sida biyaha, gaaska, hawada iyo uumiga waxaa lagu sameeyaa si toos ah laba-dhinac alxanka arc hoostiisa ama alxanka hal dhinac ah.
