I-ASME wuphawu lokuthengisa olubhalisiwe lwe-American Society of Mechanical Engineers.

Ububanzi

Leli zinga lihlanganisa ukulinganisa kobukhulu bepayipi lensimbi elihlanganisiwe nelingenamthungo lamazinga okushisa aphezulu noma aphansi nezingcindezi.Leli payipi lamagama lisetshenziswa njengoba lihlukaniswa neshubhu ukuze lisebenze emikhiqizweni yamashubhu enobukhulu obuvame ukusetshenziselwa amapayipi namasistimu amapayipi.

Usayizi

Usayizi wewonke amapayipiikhonjwa ngosayizi wepayipi ojwayelekile.

Ukwenziwa kwepayipi i-NPS 1/8 (DN 6) kuya ku-NPS 12(DN 300) kuhlanganiswe kusekelwe kububanzi obujwayelekile obungaphandle (OD).Le OD ekuqaleni yakhethwa ukuze ipayipi eline-OD evamile futhi elinogqinsi oluvamile lwenkathi libe nobubanzi bangaphakathi(ID) obucishe bulingane nosayizi wegama.

Yize kungekho budlelwano obunjalo phakathi kogqinsi olujwayelekile olukhona-OD kanye nosayizi wegama - lab' osayizi bamagama kanye nama-OD ajwayelekile ayaqhubeka nokusetshenziswa"njengokujwayelekile".

Izinto zomshado

Izindinganiso zobukhulu zamapayipi ezichazwe lapha ezemikhiqizo embozwe ekucacisweni kwe-ASTM.
