Iyatọ Laarin ASTM A234 WPB ati WPC
ASTM A234 WPB ati WPC jẹ awọn iṣedede ohun elo ti iwọn otutu yara iwọn otutu ti Amẹrika, irin ti awọn ohun elo titari, ti a lo lati ṣe awọn igunpa, awọn tee, awọn ori nla ati kekere, awọn fila, awọn igbonwo, bbl Sibẹsibẹ, awọn iyatọ diẹ wa ninu akopọ kemikali ati awọn ohun-ini ẹrọ laarin awọn meji: awọn C akoonu ti WPC ká kemikali tiwqn ni die-die ti o ga ju WPB. Fun awọn ohun elo igbekalẹ gbogbogbo, WPC le rọpo WPB, ṣugbọn o ṣe pataki fun ibajẹ wahala. Bẹẹni, o nilo lati ṣe akiyesi pe kikankikan giga le ma wulo, ati pe o nilo itupalẹ kan pato. Agbara fifẹ ti WPC ga ju WPB lọ. Nitorinaa, WPB ati WPC ko le ṣee lo ni awọn ohun elo BARRED TEE. Ti o ba ti oniru sipesifikesonu ni WPC, WPB ko le ṣee lo; ti o ba ti awọn oniru sipesifikesonu lo WPB ati ki o fe lati lo WPC dipo, awọn eniti o yẹ ki o gba gba.
Ni gbogbogbo, ipinsi igbonwo ni a yan ni ibamu si boṣewa.

2. Ni ibamu si ọna iṣelọpọ, o le pin si titari, titẹ, fifun, simẹnti ati bẹbẹ lọ.
3. Gẹgẹbi awọn iṣedede iṣelọpọ, o le pin si ipilẹ orilẹ-ede, boṣewa ina mọnamọna, ọkọ oju omi ọkọ oju omi, boṣewa kemikali, boṣewa omi, ati bẹbẹ lọ.
4. Ni ibamu si rediosi ìsépo rẹ: o le pin si igbonwo rediosi gigun ati igbonwo rediosi kukuru. Awọn igbonwo rediosi gigun n tọka si iwọn ila opin ita ti tube ti radius ti ìsépo jẹ dogba si awọn akoko 1.5, iyẹn R = 1.5D; igbonwo rediosi kukuru n tọka si rediosi ti ìsépo rẹ ti o dọgba si iwọn ila opin ita ti tube, eyun R = 1.0D. (D jẹ iwọn ila opin ti igbonwo, R jẹ rediosi ti ìsépo).
5. Ti o ba pin nipasẹ ipele titẹ: awọn iru 17 ni o wa, eyiti o jẹ kanna gẹgẹbi awọn iṣedede paipu Amẹrika, pẹlu: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS; awọn meji ti o wọpọ julọ ni STD ati XS.
