PT umbala wokuthola

1.如何运作：

A penetrant containing a colorant (usually red) is applied to the surface of the workpiece, and the penetrant will penetrate into the open defects on the surface. The excess penetrant on the surface is then removed, and a developer (usually white) is applied. The developer absorbs the penetrant in the defect, forming a clear red defect display against a white background, thereby determining the location, shape, and size of the defect.

2. Vorteil:

（1）Ukuthola izinkinga zephezulu: Ingakwazi ukuthola kahle izinkinga zephezulu ezifana nezikhala (njengokukhala kokuhlanganisa nezikhala zokucindezela), amaphuzu, izikhala, ukungabikhona, kanye nokungaphelele kokuhlanganiswa (izikhala zephezulu) kumafitthi e-carbon steel tee. Lezi zinkinga zingaholela ekuphumeleleni kokuphuma kwe-fluid, ukulahleka kwengcindezi, noma ukuphuka kwesakhiwo.

（2）Ensuring safety: Tees are commonly used in pipeline systems, performing flow diversion or converging functions. Surface defects can expand under pressure, causing leaks or even explosions. PT testing can detect defects early and prevent safety accidents.

（3）Ukulawula ikhwalithi yomkhiqizo: Ngesikhathi sokukhiqizwa kwepiphu (njengokufaka nokuhlanganisa), ukuhlolwa kwe-PT kungasebenza njengendawo yokulawula ikhwalithi ukuze kutholakale ukuhambisana kwenqubo (njengokuthi izilungiselelo zokuhlanganisa zifanele) futhi kuqinisekiswe ukuthi umkhiqizo uhambisana nezindinganiso zokwakha.

（4）Zwidziwiso: Ayikhethiwe ngohlobo lwezinto ezisebenzayo futhi ikakhulukazi ifanele ukuhlola izakhiwo eziyinkimbinkimbi (njengokuhlangana nezindawo zokuhlangana) kumafitilana e-tee. Iphinde idinge imishini elula (ayidingi imishini enkulu), ukusebenza okuguquguqukayo, kanye nezindleko eziphansi.
