Izidingo ze-Elongation: Njengokwejwayelekile

Ukwehluka Okuvumelekile Kwesisindo Nobukhulu:

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 Komshini kwe-ASTM A672 B60/B70/C60/C65/C70 LSAW Ipayipi Lensimbi Lekhabhoni:

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.

Ukupakisha i-ASTM A672 B60/B70/C60/C65/C70 LSAW Ipayipi Lensimbi Lekhabhoni:

● Ipayipi elingenalutho noma i-Black / Varnish coating/Epoxy coating/3PE (ngokwezidingo zekhasimende);

● 6"nangaphansi kube izinyanda ezinezihlilingi ezimbili zikakotini;

● Kokubili kuphetha ngabavikeli bokugcina;

● I-Plain end, i-bevel end(2"nangaphezulu ene-bevel ends, degree: 30~35°), intambo futhi ihlanganiswe;

● Ukumaka.
