Variable Orifice Flares

The patented Steffes Variable Orifice Flare has become the industry standard with its innovative design and superior Destruction Removal Efficiency (DRE). Our variable orifice design efficiently and reliably combusts volatile organic compound (VOC) emissions with its self-adjusting flare tip that uses site pressure, eliminating the need for electricity on-site.

This innovative product design allows both high and low-pressure gas streams to be used on a single modular device, mitigating the need for multiple flares on one site. 

Achieve smokeless operation in compliance with Quad-O & 40 CFR 60.18 Environmental Protection Agency (EPA) regulations with our Variable Orifice Flare, and ensure site reliability while improving up-time with our dual-pilot offering.

We keep Steffes Variable Orifice Flares stocked in our inventory yards across the country!

Custom Site Solutions

The modularity of our Variable Orifice Flare allows you to apply a combination of tips on one or more constructs to meet the needs of each specific well site. We have a variety of in-stock flare configurations available based on flow rates, regulations, production, and operational goals. 

Once we understand your specific needs, we can provide a customized site plan including heat radiation, modeling, and equipment spacing requirements.

Flare Accessories

Steffes flare accessories allow you to customize your hardware to meet your flaring needs. Our team can help you determine which flare accessories you need to maximize the performance of your Steffes flare.

Flare Controllers

Steffes Flare Controllers are innovative, high-quality ignition and monitoring systems that provide high reliability and performance for your locations. Our controllers' dual voltage and integrated design makes installation easy, while providing you with the features needed for dependable and reliable performance, even when grid power is unavailable.

Gas Assist Rings

Improve low pressure flare combustion performance with a stainless steel Gas Assist Ring, and increase the operating range for smokeless flaring.

Extension Kits

Steffes Flare Extensions Kits extend the height of the flare to stack heights of 20’, 30', 40’, and 60'. Regardless of your site layout and gas flow rate, we have a solution to keep your equipment and your people safe.

Pilot Heaters

Steffes Pilot Heaters are designed to help producers avoid costly shutdowns caused by frozen pilots. Not only do they provide results in increased production and minimize maintenance, they can also prevent costly fines for emitting volatile organic compounds from venting unlit flares.

Retractable Pilots

Steffes Retractable Pilot Arms are a reliable solution for safer flare maintenance, eliminating the need for cranes, ladders or bucket trucks to service the flare pilot. Add it to a new flare or retrofit existing flares for service made simple.


Fit your flare with a Steffes Flare Knockout to minimize the accumulation of liquids that are condensed from relief gases. Our Knockouts are equipped with automated drain pumps and come fully pre-assembled, and can be housed in a controlled environment.

Detonation Arrestors

Protect against flame propagation in piping systems by installing a Detonation Flame Arrestor. Our bi-directional Detonation Arrestor is proven to stop ignited flammable vapor mixture approaching from either direction.
