Ipuleti yensimbi ye-ASTM A285 yeBanga A

Izinga le-ASTM A285 elensimbi yensimbi, amapuleti ensimbi aqinile aphansi futhi amaphakathi ahloselwe imikhumbi yomfutho we-fusion-welded.

Ipuleti lensimbi ngaphansi kwe-ASTM A285 lihluka ngamabanga amathathu, A, B kanye no-C, ukusetshenziswa okuvame kakhulu amapuleti e-ASTM A285 Grade C.
Okuzokwenziwa ngokubulala, ukubulawa kancane, insimbi enezimbotshana noma ezinerimu ngokukhetha komkhiqizi.

Ubukhulu: 6MM kuya ku-300MM,
Ububanzi: 1500mm ukuze 4050mm,
Ubude: 3000mm ukuze 15000mm

Amadokhumenti Akhonjiwe:

I-ASTM Sandards:

I-A20/A20M: Izidingo ezijwayelekile zamapuleti ensimbi emikhumbi yokucindezela.

Izidingo ezijwayelekile kanye nolwazi loku-oda:

Izindlela zokuhlola nokuhlola kabusha, izinqubo, ukubekezelela ubukhulu, isisindo, ikhwalithi nokulungisa izinkinga, ukumaka, ukulayisha kanye noku-oda ulwazi kuzohambisana ne-A20/A20M.
Ngaphezu kwezidingo eziyisisekelo, izimfuneko ezithile ezengeziwe ziyatholakala.
Amakhoyili awafakwa ku-A285 aze asikwe abe yipuleti.
