Alxanka dabada ee birta ah ee 45° xusullada waxay la mid tahay 90° suxulka waana qayb inta badan loo isticmaalo nidaamka tuubooyinka. Marka loo eego shuruudaha injineernimada, mararka qaarkood waa lagama maarmaan in lagu rakibo qaar ka mid ah suxullada leh xaglo yaryar, ka dibna 45 ° suxullada ayaa la isticmaali karaa. Qalabka alxanka dabada ee birta 45 ° suxulka badanaa waa la mid ah kan 90 °, oo ay ku jiraan 304 birta, 316 birta, 321 birta, iwm. iyo xoog xajin. Marka la eego qeexitaannada, cabbirka alxanka dabada birta ah ee 45° guud ahaan waxaa loo qaabeeyey oo loo soo saaray si waafaqsan heerarka caalamiga ah iyo heerarka warshadaha. Cabbirrada caadiga ah waxaa ka mid ah DN15-DN1200, dhumucda derbiga SCH5S-SCH160, XS, XXS, iwm. Marka la eego heerarka, soo saarista birta dabada alxanka 45 ° waxay u baahan tahay inay raacdo heerarka iyo xeerarka qaarkood, sida ASME B16.9, DIN 2605, GB/T12459, iwm, si loo hubiyo in tayada wax soo saarkeeda iyo waxqabadkeedu ay buuxiyaan shuruudaha heerarka la xiriira oo ay leeyihiin isku halleyn iyo xasilooni wanaagsan. Marka la eego hababka rakibaadda, marka loo eego codsiyada kala duwan iyo shuruudaha rakibaadda, hababka isku xirka kala duwan ayaa loo isticmaali karaa, sida alxanka, isku xirka dunta, isku xirka xajinta, iwm. nidaamyada kiimikada, batroolka, gaaska dabiiciga ah, dawooyinka, cuntada iyo warshadaha kale si ay u beddelaan jihada socodka iyo xagasha dhuumaha dareeraha si ay u buuxiyaan shuruudaha nidaamka iyo in la hubiyo badbaadada nidaamka dhuumaha iyo xasiloonida.
