Mapaipi esimbi asina musono anogona kukamurwa kuita ASTM American standard seamless simbi pombi, DIN German standard seamless simbi pombi, JIS Japanese standard seamless simbi pombi, GB yenyika musono simbi pombi, API musono simbi pombi uye mamwe marudzi maererano nemiyero yavo. ASTM American standard seamless simbi mapaipi anonyanya kushandiswa pasi rose, uye marudzi awo akasiyana. Iwo akakodzera paramita eASTM isina musono simbi mapaipiASTM a179/179m/sa179/sa-179m American standard seamless simbi pombi dzakanyorwa sezvinotevera
application
Inokodzera mapaipi esimbi anoshandiswa mu tubular heat exchangers, condensers uye zvakafanana kupisa kupisa michina.

Seamless simbi pombi kugadzira maitiro. Zvinoenderana nemaitiro ayo ekugadzira, pombi dzesimbi dzisina musono dzakakamurwa kuita pombi dzesimbi dzisina musono dzinopisa, pombi dzesimbi dzisina musono dzinodhonzwa, dzinobowa uye dzakatambanudzwa dzesimbi isina musono, uye pombi dzesimbi dzisina musono dzakasimudzwa. Matanho maviri ekutanga anoshandiswa kugadzira mapaipi esimbi asina musono-akawanda, dhayamita rawo rinowanzoita 8-406, uye ukobvu hwemadziro kazhinji 2-25; iwo maviri ekupedzisira maitiro anoshandiswa kugadzira hombe-caliber gobvu-yakavezwa seamless simbi pombi, dhayamita rayo rinowanzoita 406-1800, uye ukobvu hwemadziro i20mm-220mm. Maererano nekushandiswa kwayo, inogona kukamurwa kuvamapaipi esimbi asina musono ezvivakwa, mapaipi esimbi asina musono ezvinwiwa, mapaipi esimbi asina musono emaboilers,uyemapaipi esimbi asina musono emapaipi emafuta.
