Controls Southeast, Inc.

Over the past 40 years, we have been engineering, designing, and building steam tracing systems to heat piping, tanks, vessels, valves, pumps, and instruments. Our experience with steam tracing systems and specialty fabrication has led to recognized expertise in heat transfer, fluid flow, piping design, and the ASME Codes. Based on your thermal needs (thermal maintenance, freeze protection, or heat-upcool-down), we determine the right system for your steam tracing application, whether that be a weld-on or bolt-on jacketing solution. We offer the following products to solve your steam tracing needs:

For many years, refineries and gas plants have employed below-ground seal legs to prevent process vapor from entering the sulfur pit or collection vessel. While seal legs perform this function well, they are prone to water intrusion and mechanical plugging, which results in costly repairs and unplanned SRU downtime. To address issues with current technology, CSI has partnered with oil and gas industry leaders to develop an above-ground sulfur seal solution: the SxSeal™ 1000. CSI’s patent-pending SxSeal™ 1000 design ensures reliable sealing performance while enabling continuous SRU operation. Moreover, the SxSeal™ 1000 is backed by CSI’s engineering expertise, expansive production capacity, and exemplary customer service. As such, CSI’s SxSeal™ 1000 delivers the technical and commercial value you’ve come to expect from CSI for over 50 years.

Most process instrumentation is sensitive to temperature; not only must the instrument or meter be kept at a constant temperature for successful operation, but temperature uniformity can also be critical to instrument performance. ControHeat® jackets are perfect for these applications, particularly since their unusual geometry can make heating via weld-on jacketing and tube tracing almost impossible.

Safe flow confirmation in Sulfur Recovery Unit rundown lines For many years, refineries and gas plants have employed methods for viewing liquid sulfur flow through their rundown lines, including look boxes and various sight glass devices. Standard look box designs require the operator to open a hatch door to view the liquid sulfur running through the piping. This activity potentially exposes the operator to H2S vapor andor liquid sulfur spray. To limit operator exposure risks, many attempts at closed sulfur viewing devices using sight glass ports have been introduced. The common issue with those devices, however, is fogging of the sight glass which hinders visibility of the liquid sulfur flow. Addressing issues with current technology, CSI has partnered with oil and gas industry leaders to develop a safe, reliable sulfur flow indication device. CSI’s patent-pending SxView™ design ensures consistent, safe visual confirmation of liquid sulfur flow. Moreover, the SxView™ is backed by CSI’s engineering expertise, expansive production capacity, and exemplary customer service. As such, CSI’s SxView™ delivers the technical and commercial value you’ve come to expect from CSI for over 50 years. The benefits of the SxView™ include: Safe, visual confirmation of liquid sulfur flow No sight glass fogging or solid sulfur freezing Easy to install Rod-out capability Easy to maintain

Specialty fabrication has been at the core of our business since we began producing jacketed piping in 1976. Unlike process (unjacketed) piping, jacketed piping presents a maze of potential problems that requires special knowledge and skill to navigate successfully. Most fabricators and contractors are ill equipped to resolve Code conflicts with design criteria, thermal stresses, heating medium routing and stresses, rigorous testing procedures, and complete documentation. Our vast experience with jacketed piping and various metals has enabled us to produce a wide range of specialty products, including: ASME Code stamped pressure vessels Precision manifolds Single-pass stacked heat exchangers Degassing columns Modular equipment skids Sulfur seal legs SxSeal™ 1000 Sulfur Trap SxSeal™ 2000 Sulfur Trap Sulfur look boxes Complex polymer manifolds are a good example of the type of specialty products we are capable of producing. During operation, polymer manifolds are subject to high pressures and high temperatures. They also go through regular "burn-out" maintenance cycles. These are tough conditions for equipment that should last for 20 years. Furthermore, all dimensions must be maintained within 132”! This is a tall order, particularly considering the heavy wall thicknesses often required for these processes can lead to significant weld distortion. Through the use of precisely aligned fixtures and expert craftsmen, we ensure the high quality of workmanship for polymer manifolds. In fact, our reputation for high quality has led to our being an alliance supplier for several worldwide companies.

Heat Transfer Compound, often referred to as heat transfer mastic, is a compound used to enhance the thermal performance of bolt-on heating products. The compound is applied to the bolt-on jacket at time of installation. Heat transfer compound consists of graphite and one or more binder components which are formulated for different applications. Graphite is a good heat conductor with half the thermal conductivity of aluminum and more than 100 times the conductivity of air. For ControTrace® heating elements and panels, CSI recommends its Grade-B ControTrace® Thermal Compound. Grade-B is a non-hardening compound composed of a high-temperature petroleum derivative and graphite. Its maximum service temperature is 400°F. At room temperatures, Grade-B has the consistency of heavy grease. Its workability decreases with decreasing ambient temperature, becoming very stiff near freezing temperatures. Grade-B is not soluble in water. It will dissolve in light mineral oils. It has an unlimited shelf life and is provided in one-gallon containers.
