Safety Considerations for Pneumatic Pressure Testing
Safety considerations for pneumatic pressure testing. Safety considerations for pneumatic pressure testing. Published October 2023 Keywords Pneumatic Pressure Test Stored Energy Minimum Safe Distance Scaled Consequence Factor ASME PCC-2 Repair of Pressure Equipment and Piping Share Summary Pneumatic pressure testing poses a significant health and safety risk due to the stored energy of the test gas, especially on larger volume piping. This can affect the operations of clients or construction activities and should be considered when specifying pneumatic pressure tests. Safe distances for personnel are proscribed in ASME PCC-2 Repair of Pressure Equipment and Piping. Minimum safe distance is 30m (100ft) and increases with stored energy and risk of fragments being thrown. The safe distance can be reduced utilizing mitigation techniques included in ASME PCC-2. When specifying a pneumatic pressure test always consider stored energy and look to eliminate the need for the testing or substitute hydrostatic. Reducing the safe distance below 30m (100ft) should always be a last resort. Codes and Standards ASME PCC-2 Repair of Pressure Equipment and [...]
Pilot Plant Produces Excellent Wastewater Treatment at Local Beef Abattoir
JNE installed a pilot plant at a beef abattoir to evaluate the treatment effectiveness and projected operating costs by treating actual wastewater streams generated from the plant. The tremendous performance of the pilot plant confirmed to the client that a DAF based system is the most cost effective solution for their facility.
Cost-Effective Polymer Make Down and Preparation Unit
JNE Environmental has developed a very cost effective dry polymer make down and preparation unit. This system is fully automatic and can prepare 1,000 litres of properly mixed and aged polymer every 2.5 hours with an accuracy of +/- 0.0002% by weight.
New Coagulant Maximizes DAF Performance and Reduces Waste Removal Costs
At the forefront of wastewater treatment technology, JNE Environmental is continuously developing new products and chemistries to help treat our customers’ wastewater. A prime example of this is the newly developed JNE 2890 coagulant. JNE 2890 has been specifically engineered to increase efficiency and reduce the overall cost of Dissolved Air Flotation (DAF) based systems.
Dissolved Air Flotation (DAF) Unit and Stripper Tower Delivery to Laundry Company
Due to the potential for foaming caused by the presence of soap, coupled with the requirement for foaming tolerance, a packed column stripper was selected for the separation process. An FS-120 Dissolved Air Flotation (DAF) unit was chosen to remove the TSS and FOG, as well as to reduce the Biological Oxygen Demand (BOD). The DAF, in conjunction with our engineered chemical solutions JNE 281 (coagulant) and JNE 3003 (flocculant), showed excellent results.
Delivering Exceptional Fluoride Removal — Right to Your Door
JNE Environmental has designed, built in-house, and shipped Fluoride batch treatment and pH correction systems to an ultrapure chemical manufacturer in Reno, Nevada. The fluoride treatment system is comprised of an incoming equalization tank, a specialized cone-bottom reaction tank, sludge waste holding tank, and a discharge effluent equalization tank to allow for safe discharge into the sewer system.
Carbon Dioxide pH Correction System is an Eco-Friendly Treatment Solution
JNE Environmental has developed a cost-effective and environmentally-friendly pH correction solution — using the same principles as carbonated soda. This process can achieve the desired pH correction without the use of expensive plastics, dangerous industrial acids, or specialized protective equipment, and does not result in the addition of Chlorides or Sulfates.
