Flanges & Fasteners

Flanges and fasteners are essential mechanical components that serve as the backbone of industrial assembly and piping systems. They are used to connect, secure, and seal pipes, valves, pumps, and other equipment in high-pressure and high-temperature environments. Our product line includes a comprehensive range of high-performance flanges and fasteners engineered to meet international standards and diverse industrial requirements.


🔹 Flanges

Flanges are used to connect pipes, facilitate maintenance, and allow for easy inspection and modification of systems. We offer a wide range of flanges made from carbon steel, stainless steel, alloy steel, and special alloys, with various pressure ratings.

Types of Flanges We Supply:

Flange TypeDescription
Weld Neck FlangesIdeal for high-pressure applications, welded to pipe neck
Slip-On FlangesEasy to install and align, lower pressure ratings
Blind FlangesUsed to close pipe ends, essential for pressure testing
Socket Weld FlangesFor small-diameter high-pressure piping
Threaded FlangesUsed where welding is not feasible
Lap Joint FlangesPaired with stub ends, ideal for systems requiring frequent disassembly
Orifice FlangesUsed with flow meters for measurement systems
