3 Custom Built Disc-Spring Arrestors with Clamps
February 28, 2003
3 Custom Built Disc-Spring Arrestors with Clamps
The disc-spring arrestors provide resistance by utilizing disc springs (sometimes referred to as Belleville® washers) stacked in a series within the assembly housing to produce a specific spring rate. By utilizing large (over 8 diameter) disc springs, very high spring rates may be obtained. The arrestors are capable of operating in both tension and compression.
The housing, end bracket, and extension pieces of the spring arrestor are made form A-36 carbon steel. The disc springs are made from ASTM A-1075 spring steel. One clamp (for design temp. of 688 degrees F.) was made from carbon steel and two clamps (for design temp. of 1054 degrees F.) were fabricated from A-387 GR.22 Chrome-Moly steel.
The diameter of each disc spring was 9 with a thickness of 1. The overall pin-to-pin dimension for the assemblies varied with a minimum of 35 and a maximum length of 57. The maximum length that can be accommodated is 120. The clamps were made for 18 and 30 diameter pipes.
The shock arrestor will see a maximum operating load of 43,000 lbs. The spring rate of each arrestor was designed at 40,000 lb./in. The spring arrestors are designed for a maximum displacement of 2. The arrestors were tested to verify spring rate and to confirm the operation of the pipe hanger assembly.

40" Diameter, Alloy Yoke Clamp
October 12, 2001
40″ Diameter, Alloy Yoke Clamp
PT&P specially designed and manufactured a heavy duty, 40-inch diameter, alloy yoke clamp (cut from a 6″ thick plate) for a Power Plant in Mississippi. The clamp was designed for a 70,000 lb load and is to support a 40″ diameter, high pressure main steam line. The u-bolt was made of a 3″ diameter bar. In order to prove the design of this clamp, Finite Element Analysis was used to simulate the loads and stresses that it may experience in the field. The model shows the stresses at every point by a color coding system.
