The ASME Story

Dennis Alexander Service Tip of the Month

ASME is best known for improving the safety of equipment used in manufacturing and construction particularly boilers and pressure vessels.

Expansion and Compression Tanks – Which Tank? – Part 8

Norm Hall Monday Morning Minutes

Choosing to use a Bell and Gossett ASME bladder style expansion tank, ASME diaphragm style tank, or ASME standard compression tank in your hydronic system will depend on several factors. One important consideration in choosing which tank to use depends on the type of “air control” system you design. Air elimination systems depend on automatic air vents to continually remove the air from the hydronic system. [Read more…]

Types of Tanks – Expansion and Compression Tanks – Part 7

Norm Hall Expansion & Compression Tanks, Monday Morning Minutes, Tanks

What is the difference and when should I use them? Let’s start with ASME. In commercial and institutional applications, ASHRAE, as well as most codes require the pressure vessels carry an ASME U stamp. This assures the owner and the owner’s insurance carrier that the vessel was inspected by an independent appraiser and registered with the National Board. [Read more…]

Maximum Pressure of Expansion and Compression Tanks – Part 5

Norm Hall Monday Morning Minutes

Maximum pressure in a hydronic system depends on a number of variables. Last week we used an example to introduce the maximum pressure at the expansion tank. Let’s look at a couple more examples. EXAMPLE TWO: Figure 1 shows a one line diagram of a heating system with a boiler and pumping system. [Read more…]
