1. Ububanzi Bangaphandle-Kusekelwe esilinganisweni esiyindilinga ±0.5% sobubanzi obushiwo bangaphandle.
2. Ngaphandle Kwe-Roundness-Umehluko phakathi kwamadayamitha angaphandle amakhulu namancane.
3. Ukuqondanisa-Kusebenzisa i-10 ft (3m) yokuqondisa ebekwe ukuze iziphetho zombili zithintane nepayipi, 1/8 in. (3mm).
4. Ukuqina-Ubukhulu obuncane bodonga kunoma iyiphi indawo epayipini akumele bube ngaphezu kuka-0.01 in. (0.3mm) ngaphansi kogqinsi olushiwo.
5. Ubude obuneziphetho ezingashintshiwe buyoba phakathi kuka--0+1/2 in. (-0+13mm) walokho okushiwo.Ubude obuneziphetho ezenziwe ngomshini buzoba njengokuvunyelwana ngabo phakathi komkhiqizi nomthengi.
Ukuhlolwa Kwengcindezi—Izici eziqinile eziguquguqukayo zelunga elishiselwe zizohlangabezana nezidingo ezincane zamandla okugcina aqinile wento yepuleti elishiwo.
Ukuhlola okugobile okuqondiswa-okuguquguqukayo—Isivivinyo sokugoba siyokwamukeleka uma kungekho mifantu noma okunye ukukhubazeka okudlula u-1/8 in. (3mm) kunoma iyiphi indlela ekhona ensimbi yokushisela noma phakathi kokushisela nesisekelo sensimbi ngemva kokugoba.
Ukuhlolwa Kwezithombe Zomsakazo-Ubude obugcwele be-weld ngayinye yekilasi X1 ne-X2 buzohlolwa ngokwemisakazo ngokuhambisana futhi kuhlangatshezwane nezimfuneko ze-ASME Boiler and Pressure Vessel Code, Isigaba sesikhombisa, isigaba UW-51.
Ipayipi eliqediwe ngeke lingabi nasici futhi lizoba nesiphetho esifana nomsebenzi.
A. Igama noma umaki womkhiqizi.

D. Ibanga( A noma B).
E. Uhlobo lwepayipi( F, E, noma S).
F. Ingcindezi yokuhlola(ipayipi lensimbi elingenamthungo kuphela).
G. Inombolo Yokushisa.
H. Noma yiluphi ulwazi olwengeziwe olucaciswe ku-oda lokuthenga.
● Ipayipi elingenalutho noma i-Black / Varnish coating/Epoxy coating/3PE (ngokwezidingo zekhasimende);
