To The Specifying Engineer: In 1962 we introduced our first “HVAC ENGINEERING SPECIFICATION.” While the 1962 approach was very well received and filled a void, it was made up of many individual specifications rather than presented in an organized format.It had no meaningful minimum static deflection guide and engineers found it hard to work with.…
First Presented at the Fall Lecture Series NOISE AND VIBRATION PROBLEMS AND SOLUTIONS New York Chapter-A.S.H.R.A.E. November 1966 Condensed & Published in Air Conditioning, Heating & Refrigeration News – 1-29-68 Until a very few years ago the vibration isolator recommendations for air conditioning equipment were more a matter of tradition than science. It was well…
BALL JOINTS When ball joints are installed at each end of a pipe offset, the system can accommodate much larger movements with much lower anchorage requirements than solid pipe in the same configuration. We not only sell our flanged and weld end ball joints, but we engineer the systems should there be no specifications or…
Piping Guides Our newly developed Adjustable Sliding Guides offer many improvements over other guides: one size guide for all thicknesses of insulation, less friction with our Stainless Steel Slides, sturdier construction and they can be used as load supports as well. We still carry spider guides as well. Anchors are manufactured to order. BULLETINS &…
HOUSED EXPANSION JOINTS Expansion Compensators and Housed Expansion Joints are basically a bellows that is protected by and guided within a pipe housing. While the industry offers two styles, one of which is referred to as “internally” and the other “externally pressurized”, they both serve the same function but we prefer the “externally pressurized” for…
EXPANSION COMPENSATORS Expansion Compensators and Housed Expansion Joints are basically a bellows that is protected by and guided within a pipe housing. While the industry offers two styles, one of which is referred to as “internally” and the other “externally pressurized”, they both serve the same function but we prefer the “externally pressurized” for improved…
BELLOWS PUMP CONNECTORS All bellows differ from Stainless Steel Hose in the corrugation configurations. Bellows are deeper and wider, and they are made of heavier material, to handle the pressures without braid. A very common location for our 2 ply Bellows is at the pumps. The face to face dimension is equal to the length…
EXPANSION JOINTS Many expansion joints are custom manufactured to diameters as large as 8 feet (2.4m). The construction varies, depending on the operating pressure and the required movements. We can provide these unusual constructions in virtually every configuration. We can build to your specific product description or complete our own recommendations based on your movement…
VEE ASSEMBLES Many buildings are separated by expansion joints through the walls and floors. During an earthquake, the two adjacent parts resonate with relative motion of as much as ± 4” (100mm) in shear as well as toward and away from one another. Vertical motion is minimal. We have developed a unique product to handle…
