Premium Flanges For Industry Pipeline System
Looking for world-class flanges for your industry? We offer premium forged steel flanges with unmatched strength and top-notch performance.
Blind Flanges
Blind flanges temporarily or permanently block the flow of fluids or gases in a pipeline. It is beneficial when a pipeline needs to be disconnected from the rest of the system for maintenance, repairs, or other purposes.
Plate Flanges
A plate flange is a flat, circular disc welded to a pipe’s end enabling the flange to be bolted to another pipe. It is often referred to as flat flange, plain flange and flange slip, etc. It is usually used in fuel and water pipelines.
Weld Neck Flanges
A weld neck flanges transfers stress to the pipes, lessening the high-stress concentration at the bottom of the flange. This attribute of weld neck flanges makes them suitable for the oil and gas industry.
Slip-On Flanges
Slip-on flanges on the pipe and connect without utilizing additional tools for installation. The design of slip-on flanges allows direct and secure pipe connections that can withstand high pressure and temperature conditions without leaking or bursting
Threaded Flanges
A threaded flanges connects a device securely to a pipe without welding. Threads create a secure and leakage-free connection between the flange and the pipe. Threaded flanges work well for fixing equipment quickly.
Socket-Weld Flanges
Socket-weld flanges are suitable for smaller-diameter pipes and operate in lower-pressure/temperature systems. Insert the pipe into the female socket of socket-weld flanges, and then a fillet weld is used around the top to create a connection. It allows a seamless flow of liquid or gas in the pipe.
