Pedestals and Beams in Operation

The 54" suction line carrying gas to a gas compressor at a rate of 1.7 million lb./hr. developed a severe vibration. The deflections in the line were up to 3/4" and it was fully observable during operation.

PT&P designed and manufactured a special elevated hold-down clamp, including a unique laminated vibration dampening lining. The entire pipe hanger assembly stands 22' high and is coated with a carboline zinc finish. After installation and resumption of operations, the vibrations are now almost imperceptible.

ASME Code Pig Launchers and Receivers

Safety Locking System

One starter key per launcher/receiver is kept in a box located in the control room. Each lock is executed with two keys. When the first valve is opened with this starter key, it releases the second key. This key is transferred to next valve which releases second key from that valve and so on and so forth. This process guides the operator through the specified sequence for opening and closing valves with unique a key for each step.

F-Type Variable Spring Supports

An assortment of standard variable spring supports were manufactured ranging in size from 8-5/8" to 12-3/4" dia. with installed heights ranging from 9-7/16" to 18-1/8". The F-Type pipe hanger assembly is used to support the pipe from below and are typically mounted to concrete pads via anchor bolts or welded to structural steel. The various springs shown are designed for operating conditions ranging from loads of 1750 lb. with .02" travel to 21,280 lb. loads with .13" travel. As with all of our variable supports, these were quality checked with a 100% spring coil deflection test and a load cell calibration to set the assembly at the prescribed installed load.

Big Ton Springs with a Custom 3-Coat Paint System

PT&P fabricated big ton spring supports for an expedited delivery of six weeks from conceptual design to final delivery. The big tons measure 26" long x 26" deep x 34-5/8" tall and will be used to support substantial vertical loads while simultaneously providing a base support structure. They are designed for operating loads of 36,000 lb. with a travel of .5625" down.

Due to the harsh and corrosive environment, the exposed metal surfaces were finished with a three-coat urethane paint while the threaded components were cadmium plated with a blue Fluorocarbon coating. The big tons were also salt water spray tested according to ASTM B117 standards, and load tested to verify the springs' functionality throughout the entire travel range.

100 Type F Vertical Constant Supports

These are constants known as 100 type F vertical constant supports. They support pipe from below by means of a sway strut. They are fabricated from A36 carbon steel and hot dipped galvanized to prevent rusting. The constant in the first picture maintains a constant load of 7,000 lb. while the constant in the second picture maintains a load of 9,000 lb. on the pipe throughout its 4” of total travel. They are 36” high with two gussets at the base plate to prevent the coil housing from collapsing under test loading and normal operation. Standard load and travel testing was performed on the constant to insure proper field operation.
