SAMSON VETEC – Rotary Plug Valves for High Flow Rates

VETEC, an associated company of the SAMSON GROUP, specializes in rotary plug valves. They are mainly used in processes where high flow rates and low or medium pressure drops are frequently encountered. VETEC’s Maxifluss rotary plug valves combine the advantages of conventional globe valves, butterfly valves, and ball valves into one instrument. Thanks to the double eccentric design of the rotary plug, it only comes into contact with the valve seat when the valve is completely closed; the plug and seat do not touch even when the valve is only slightly open. An added benefit of the valves is that, when they close, any fibers contained in the process medium are cut off and cannot impair the valves’ proper functioning. Tight valve shut-off is guaranteed even at high pressure drops, while a high rangeability ensures precise control. The plug does not obstruct the flow path when the valve is open and, as a result, the fluid can flow through the entire cross-section of the pipe.

SAMSON PFEIFFER – High-Grade PTFE or PFA Lined Valves

Pfeiffer, an associated company of the SAMSON GROUP, specializes in producing valves with high-grade linings made of PTFE or PFA. Lining the intricately shaped inside surfaces of a valve is certainly an engineering challenge, especially to achieve a uniform thickness and the highest lining quality, without cavities or inclusions. Various ceramic linings as well as globe valves, butterfly valves, and ball valves made of stainless steel and exotic alloys, such as titanium and tantalum, complete Pfeiffer’s product range.

An additional area of Pfeiffer’s expertise is turnkey pigging installations. The company specializes in planning and manufacturing turnkey pigging systems tailored to the customers’ specific needs. Pigs are run through a pipeline section to efficiently clean out excess liquids and solids. This reduces product loss and allows different media to run through the same pipe after one another without being mixed or contaminated.

Q: What are the federal requirements for aboveground storage tanks under the Clean Water Act?

Federal requirements under the Clean Water Act are summarized below:

General Description – Storage tanks that are aboveground, regardless of whether they are used for to store petroleum products, hazardous waste, or other hazardous material.


Summary of Federal Requirements
– Aboveground storage tanks (ASTs) used for the storage of petroleum products is regulated primarily under 40 CFR 112. The regulation does not actually use the terms “aboveground storage tank.” Instead, the term “bulk storage container” is used and is defined as “any container used to store oil. These containers are used for purposes including, but not limited to, the storage of oil prior to use, while being used, or prior to further distribution in commerce. Oil-filled electrical, operating, or manufacturing equipment is not a bulk storage container.”

A bulk storage container is 55 gallons or greater and may be aboveground, partially buried, bunkered, or completely buried. “Bunkered tanks” are defined as “a container constructed or placed in the ground by cutting the earth and re-covering the container in a manner that breaks the surrounding natural grade, or that lies above grade, and is covered with earth, sand, gravel, asphalt, or other material. A bunkered tank is considered an aboveground storage container for purposes of 40 CFR 112.”

Design – A container (i.e. storage tank) cannot be used for the storage of oil unless its material and construction are compatible with the material stored and conditions of storage such as pressure and temperature.

All bulk storage container installations must be constructed so a secondary means of containment is provided for the entire capacity of the largest single container and sufficient freeboard to contain precipitation. Diked areas must be sufficiently impervious to contain discharged oil. While dikes, containment curbs, and pits are commonly employed for this purpose, an alternative system consisting of a drainage trench enclosure that must be arranged so that any discharge will terminate and be safely confined in a facility catchment basin or holding pond may also be used.

Each bulk storage container installation must be engineered or updated in accordance with good engineering practice to avoid discharges, including at least one of the following devices:

  • High liquid level alarms with an audible or visual signal at a constantly attended operation or surveillance station (NOTE: In smaller facilities, an audible air vent may suffice.)
  • High liquid level pump cutoff devices set to stop flow at a predetermined container content level
  • Direct audible or code signal communication between the container gauge and the pumping station
  • A fast response system for determining the liquid level of each bulk storage container such as digital computers, telepulse, or direct vision gauges (NOTE: If you use this alternative, a person must be present to monitor gauges and the overall filling of bulk storage containers.)

Management – Control leakage through defective internal heating coils is by monitoring the steam return and exhaust lines for contamination from internal heating coils that discharge into an open watercourse or pass the steam return or exhaust lines through a settling tank, skimmer, or other separation or retention system.

The drainage of uncontaminated rainwater is not allowed from the diked area into a storm drain or discharge of an effluent into an open watercourse, lake, or pond, bypassing the facility treatment system unless the facility:

  • Normally keeps the bypass valve sealed closed
  • Inspects the retained rainwater to ensure that its presence will not cause a discharge
  • Opens the bypass valve and reseals it following drainage under responsible supervision
  • Keeps adequate records of such events, for example, any records required under permits (i.e., NPDES)

Testing/Monitoring – Each aboveground container must be tested for integrity on a regular schedule and whenever material repairs are made. The frequency of and type of testing must take into account container size and design (such as floating roof, skid-mounted, elevated, or partially buried). In July 2012, EPA released a helpful fact sheet on bulk storage container inspections. The facility must combine visual inspection with another testing technique such as hydrostatic testing, radiographic testing, ultrasonic testing, acoustic emissions testing, or another system of non-destructive shell testing. Comparison records must be kept and the container’s supports and foundations also inspected. Personnel must frequently inspect the outside of the container for signs of deterioration, discharges, or accumulation of oil inside diked areas. Liquid level sensing devices must be regularly tested to ensure proper operation. Effluent treatment facilities should observed frequently enough to detect possible system upsets that could cause a discharge. If field-constructed aboveground containers undergo a repair, alteration, reconstruction, or a change in service that might affect the risk of a discharge or failure due to brittle fracture or other catastrophe or has discharged oil or failed due to brittle fracture failure or other catastrophe, the container is evaluated for risk of discharge or failure due to brittle fracture or other catastrophe and appropriate actions taken.

Mobile/Portable AST – Mobile or portable oil bulk storage containers must be positioned or located to prevent a discharge and furnished with a secondary means of containment, such as a dike or catchment basin, sufficient to contain the capacity of the largest single compartment or container with sufficient freeboard to contain precipitation.

Regulatory Applicability – 40 CFR 112 applies to petroleum oils and non-petroleum oils, animal fats and oils and greases, and fish and marine mammal oils; and vegetable oils (including oils from seeds, nuts, fruits, and kernels). 40 CFR 112 also applies to any owner or operator of a non-transportation-related onshore or offshore facility engaged in drilling, producing, gathering, storing, processing, refining, transferring, distributing, using, or consuming oil and oil products, which due to its location, could reasonably be expected to discharge oil in quantities that may be harmful, into or upon the navigable waters of the United States or adjoining shorelines, or into or upon the waters of the contiguous zone, or in connection with activities under the Outer Continental Shelf Lands Act or the Deepwater Port Act of 1974, or that may affect natural resources belonging to, appertaining to, or under the exclusive management authority of the United States (including resources under the Magnuson Fishery Conservation and Management Act) that has oil in:

  • Any aboveground container
  • Any completely buried tank (see definitions)
  • Any container that is used for standby storage, for seasonal storage, or for temporary storage, or not otherwise “permanently closed” (see definitions)
  • Any “bunkered tank” or “partially buried tank” (see definitions), or any container in a vault, each of which is considered an aboveground storage container for purposes of 40 CFR 112.)

Hazardous Materials Storage in ASTs – Depending on the type and amount of hazardous materials (e.g., gasoline, diesel fuel, other liquids) stored and/or used at the facility, EPA reporting requirements may apply.

Summary of State Requirements – ASTs are primarily regulated by states. The requirements can usually be found in environmental regulations and/or the fire code. There may be a requirement to paint the tank or a fill pipe a certain color to identify its contents, provide alarms in addition to those Federally required, and register the tank.
