Screen Guides for a Cooling Tower at a Chemical Plant
March 21, 2022

These screen guides were custom fabricated for a cooling tower at a chemical plant in Texas. These anchor bars are used to secure the screen guides to the concrete. These screen guides are 10″ in width and are 42″ in length. All components were completely fabricated from A36 carbon steel with a galvanized finish. Standard quality control inspections were performed before shipment.

Many plants, such as power, petroleum refineries, metal processing, and other industrial facilities are designed to use open recirculating systems utilizing cooling towers for heat transfer from condensers and other heat exchangers through a process called “latent heat of vaporization.”

Industrial Process Cooling TowersWithin these cooling towers, screen guides are used in a gravity-flow distribution system where supply water flows or cascades down over successive offset levels of horizontal screens or splash bars into a basin. These guides provide a means by which screens or splash bars are supported from a concrete structure. The screens are intended to lower the temperature of water by causing the water to spread over large areas to promote maximum exposure to airflow as it cascades from the top of the tower into the lower basin. One side of the guide provides a “slot” by which screens or other types of “surfaces” can be installed. The other side of the guides are fitted with bent “strip anchor bars” similar to those used for embed plates. As a manufacturer of embed plates, we also supply these for mining facilities, semiconductor plants, wastewater treatment plants, or any construction site where there is steel attached to a concrete panel or slab.

152 Variable Spring Supports for a Furnace Application at an Ammonia Plant
March 7, 2022

Ptp Variable Furnace Springs 151617

PT&P custom-designed and manufactured over 150 variable spring supports for a furnace application at an ammonia plant. The ammonia plant was the largest single train plant of its kind in the world for the leader in mineral-based commodity and specialized fertilizer production. As an important base to material for fertilizers, ammonia helps put food on the table as the engine of plant growth. Over 85% of anhydrous ammonia is used as fertilizer for the three primary nutrients of fertilizer: nitrogen, phosphates, and potash. The plant and the EPC for which these were designed and manufactured were in Europe highlighting Piping Technology and Products’ robust international footprint in the marketplace for over 47 years. We serve over 90% of the countries in the world covering almost all continents. Outside of use in the fertilizer industry, ammonia is positioned to have a key role in our renewable-based, lower carbon footprint hydrogen economy supporting on-board hydrogen carrier for fuel cell activities given its high capacity for hydrogen storage based on its molecular structure.

These furnace springs are fabricated from carbon steel and painted with a red-oxide primer to help prevent corrosion. We also designed and manufactured 304 stainless steel pipe clamps to attach the furnace springs to catalysis tubes within the furnace. They are designed to support a cold load of almost 3,000 lb./in. while operating in an area where temperatures are higher than ambient. There were a total of 173 assemblies fabricated for this project, 152 variable hangers, 3 constant spring supports, 6 ball joint rigid struts, and 12 rigid rod hangers. Special load tests were performed before shipping.
