Q: Does the six angle flange bolt and the six angle bolt have the same meaning?: Different. The head of the flange bolts is like a hat.

Q: All details, forms and websites are OK. Thank you: Nominal diameter mm inch inch (inch), commonly known as our country6 "1/8" -"8 1/4" -10 "3/8" -15 1/2, 4 points20 3/4 "6"251 "1 inches."(32) 1 "+1/4" ----401 "+1/2" inch and a half502 "2 inches"Flange due to different nominal pressure, structural types and installation methods of different thickness and size of different, please refer to the "mechanical design manual", pipe fittings.

Q: What does "-150# SO/FF" mean by flange 4?: American Standard, pressure rating of 150, hubbed flangeSealing surface plane of flange

Q: DN200 how many screws are there in the weld flange?: For welding flange DN200, many customers say the welding flange you DN200, but you and our site is not the same, your welding flange is thicker than the US, and your site we screw holes to. First of all, let us explain to you the customer, the pressure of your piping design is incorrect at first.

Q: Flange WN50 (B) -25 RF S=6 specific points: WN indicates that butt welding 50 means nominal diameter DN (B means B series diameter is 57) - 25 is pressure, new standard is 25 kg pressure, old standard is 250 kg pressure RF, sealing surface protrusion S=6 flange diameter thickness is pipe thickness

Q: How many kinds of flanges are there?: 1. The flange is divided into flange, flange, threaded flange, socket welding flange and loose flange according to connection.2. according to the form of flange sealing surfaceFlange in accordance with its form of sealing surface can be divided into flat, convex surface, concave convex surface, tongue and groove surface and ring connection surface.
