Sliding A182 Grade F316Ti 300# Sleeve Flange ASME B16.5 Caliber 141.3mm

Sliding sleeve flange A182 Grade F316Ti, 300#, the sealing surface is convex, ASME B16.5 caliber 141.3mm

A loose flange refers to a flange loosely fitted on the flange of a container or pipeline. Flange is a part that connects between shaft and shaft and is used for connection between pipe ends; it is also useful for flanges on the inlet and outlet of equipment for connection between equipment.
The loose flange is a loose flange. The flange can be made by flanging, direct turning out, or another welding ring. The advantage is that no additional torque is generated to the container or pipeline when the flange is deformed, and it is convenient to manufacture. It can be made of materials different from the container or pipeline, which is convenient for saving precious metals. The disadvantage is that the flange thickness is relatively large. It is suitable for occasions where the vessel or pipeline is lined with brittle materials and the pressure is not high.

The pressure mark specified in the standard is divided into PN mark and Class mark.
The PN mark has 12 pressure levels, namely: PN2.5; PN6; PN10; PN16; PN25; PN40; PN63; PN100; PN160; PN250; PN320; PN400.
Class is marked with 6 pressure levels, namely: Class 150; Class 300; Class 600; Class 900; Class 1500; Class 2500.

Loop flanges are divided into multiple models according to different nominal pressure, sealing surface form, flange type and nominal size.
