Are PN10 and PN16 SS 316 flange same?
PN10 and PN16 are the pressure nominal of the ASTM A182 F316 flange. The PN16 grade has higher pressure tolerance than the PN10 grade.
What is the difference between SS 316 lap joint flange and slip on flange?
The A182 F316 lap joint flange has a two piece assembly. Here a stub end and a ring type lap joint are placed over it. These flanges have bolt holes and can even be welded. A182 Gr F316 slip on flange is a versatile grade that can be slid on the piping material. Here the flange is welded with one or more fillet welds.
The AISI 316 lapped joint flange is efficiently used in applications where regular inspection and disassembly for material inspection are necessary. UNS S31600 ring type joint flange has a curved radius at bore at the face which differentiates it from sorf flanges.

What is open die forging 316 Stainless Steel Flanges?
Open die forging is a forging metal that is designed to obtain ASTM A182 grade F316 forged flange of different sizes. The metal is subjected to impact or pressure to deform it freely across all its directions. The SA 182 316 plate flange is subjected to temperatures between 500 to 2400 degrees F using heated billets. In the open die forging DIN 1.4401 RTJ flange has excellent flexibility and superior strength.
