Calle Industries

INTRODUCTION

We are one of the leading manufacturers & exporters of threaded flanges, threaded pipe flanges and stainless steel threaded flanges. These special type of flange is generally used for high pressure, yet smaller diameter applications. Their key feature is that these flanges can be assembled without welding. Threaded Flanges can be used in extremely high pressure services, thus proving impeccable working capacities.
At Calle Industries, our threaded flanges, threaded pipe flanges, and stainless steel threaded flanges can also be customized as per the client’s requirements, maintaining high quality and precision standards.

Types of Flanges We Manufacture

Calle Industries offers a types of flanges, designed to satisfy an extensive range of commercial programs:.

Weld Neck Flanges (WN)

Ideal for excessive-stress packages, weld neck flanges offer an easy transition from flange to pipe, lowering strain attention.

Slip-On Flanges (SO)

These are easy to put in and value-powerful, normally used in low-pressure packages.

Blind Flanges (BL)

Used to seal off the ends of piping systems or valves. These are pressure-resistant and perfect for trying out go with the flow structures.

Threaded Flanges (TH)

Screwed flanges that do not require welding—perfect for applications wherein welding isn’t viable.

Lap Joint Flanges (LJ)

Often used with stub ends, lap joint flanges permit for smooth alignment and are suitable for structures requiring common dismantling.

Socket Weld Flanges (SW)

Designed for small-diameter, excessive-pressure pipelines. Easy to put in and ideal for compact piping.

Orifice Flanges

Designed with holes for meter faucets for measuring drift fees in pipelines. Eight. Spectacle Blind Flanges used in pipeline systems that require regular renovation or drift interruption.
