Measurement and Control Products for the Shale Gas Industry

M.S. Jacobs provides measurement and control solutions
to the shale gas production and processing sectors.
Several areas of North America are involved with the extraction of shale gas resources. The Marcellus Formation, one of the largest shale gas production areas, is located beneath much of the coverage area of M.S. Jacobs & Associates. A substantial portion of the company's product lines have application potential throughout the layers of the industry.

The Gentherm Global Power Technologies TEG (thermo-electric generator) is a product M.S. Jacobs provides for “upstream” use on the production well pad. It provides a reliable source of electric power at off-grid locations and is preferred because of its reliability and operating principle. A TEG has no moving parts and requires little maintenance. A thermoelectric generator converts heat directly into electricity. As heat moves from a gas burner through a thermoelectric module, it causes an electrical current to flow. Thermoelectric generators are a preferred source of power in areas without reliable and abundant sunshine for photovoltaic production of electricity.

Another source of remote power are the Stirling Engine driven generators from Qnergy. Operating on any combustible fuel, these systems deliver electric power efficiently and require no maintenance. The Qnergy power units are fuel agnostic and insensitive to gas content, able to run on gas with variable caloric content.

M.S. Jacobs is also involved with solutions for midstream operations. Flexim ultrasonic clamp-on flowmeters serve as check meters at midstream processing facilities and compressor stations to measure large volumes of gas. They are also being used to help balance the load to the compressors. Other applications are on gas storage wells that are filled in the summer and pumped out in the fall-winter, taking advantage of the bi-directional measurement capability of the meter.

M.S. Jacobs also provides Magnetrol level controls and Orion visual level indicators for various level applications as well as valves and controls on other midstream and downstream applications. A primary partner to many processing companies, M.S. Jacobs provides experience, application expertise, local inventory, and ongoing support.

Expansion Joints in Process Piping Systems

due to a number of real world factors.

Piping systems of any size require consideration of stresses placed upon the system by movement resulting from a number of possible factors. In some cases, the movement is vibratory and related to the operation of connected machinery. Another common case is the expansion and contraction of piping sections due to thermal effects.

Process piping can have substantial stress applied due to thermal expansion of the piping material itself. This is especially evident when portions of the process piping are fixed in position by their mounting method. Allowances must be made for expansion of the piping material in the installed location. The design criteria will include factors that impact the expansion of the piping components, as well as the relationships between the piping and elements of their supporting structures. Expansion can produce substantial movement of pipe sections which must be accommodated by the supports and the piping itself.


One manufacturer, General Rubber Corp., manufactures a wide range of expansion joints for process piping systems of almost any size. Their expertise, acquired over many years in the field, is reflected in the numerous product variants available to meet every application condition.

One, Two, or Three Piece Ball Valve?

Ball valves are employed throughout many commercial, institutional, and industrial venues where the need to isolate part of a system is necessary, or even just to regulate the on/off condition of system fluid flow. The product variants are almost uncountable, with a version to accommodate almost any application.

When selecting a ball valve, one facet of construction will be evident in your research. There are three common types of ball valve construction; one piece, two piece, and three piece. Here are some general considerations and differences among the three types.

  • A one piece ball valve has a body and end connections formed from a single piece of material. This construction presents a comparatively reduced number of opportunities for leakage. The valve trim and seals are inserted through one of the end connections. This type of valve will not have a port size equal to the line size. The simplicity of the one piece body design tends to make their cost lower than the other versions. Once the valve is in place, it cannot be serviced without removing the entire valve assembly from the piping system.
  • Two piece ball valves generally have one piece that includes an end connection and the body, plus a second piece that fits into the first that will hold the trim in place and provide the second end connection. The construction presents an additional leak potential where the two pieces are joined, but also allows disassembly of the valve for replacement of the internals. These valves can provide full port service and bidirectional flow shutoff.
  • A three piece ball valve essentially separates the connection portions of the valve assembly from the body of the valve. These will be more expensive than either of the other two types, but their allowance for removing the valve body and trim from the piping system while leaving the connections in place may prove valuable for many applications. Full port and bidirectional shutoff can be provided by this construction.
Properly applied, all these valves will provide good service. Your selection depends on the demands of the application.
