Phapang lipakeng tsa Weld Neck Flanges le Slip On Flanges
1. Mefuta e fapaneng ea weld:
Tlhahlobo ea radiographic e ka etsoa bakeng sa li-welds tsa tjheseletsa ea molala butt, empa eseng bakeng sa molala o bataletseng oa welding flange.Mofuta oa tjheseletsa oa molala butt-welding flange le phala ke weld circumferential, ha mofuta oa welding oa flange o bataletseng oa welding le phala ke fillet weld.tjheseletsa butt ke tjheseletsa e circumferential butt, mme welding e bataletseng ke lithapo tse peli tse circumferential fillet.Phapang pakeng tsa tse peli ke hore tjheseletsa e kopanyang molala butt-welding flange le nozzle ke ea Class B seam, athe weld e kopanyang molala butt-welding flange le nozzle ke ea Class C seam.
2. Lisebelisoa tse fapaneng:
Thepa ea molala butt welding flange hangata e entsoe ka likarolo tsa tšepe tse entsoeng ka machining.Thepa ea slip-on welding flange e nang le molala e entsoe ka poleiti e tloaelehileng ea tšepe e nang le botenya bo hlokahalang ka machining.
3. Likhatello tse fapaneng tsa lebitso:
Khatello ea lebitso la molala butt-welding flange ke 1-25MPa, e phahameng.Khatello ea lebitso la molala o bataletseng oa welding flange ke 0.6-4MPa.Ha ho bapisoa le neck flat welding flange, boemo ba eona ba khatello bo tlase 'me bokhoni ba eona ba ho ikamahanya le khatello le bona bo tlase.
