Variable Spring Hangers Designed for an Upstream and Valve Project in Thailand

Variable Spring Hangers Designed for an Upstream and Valve Project in Thailand

PT&P designed and manufactured these variable spring hanger assemblies for an upstream and valve project in Thailand. The variables clamp sizes range from 6″ to 12″ diameter with installed heights ranging from 6-8/8″ to 12-1/4″ from the structure to the center of the pipe. The B-Type pipe hanger assembly uses coil springs to support the load and allow for some movement. They are furnished with one lug welded to the top of the spring casing which allows the assembly to be suspended from structural members for pipe support. All forty-seven variable spring supports were quality checked with a 100% spring coil deflection test and a load cell calibration to set the assemblies at the prescribed installed load.

Variable Spring Support Design, Size Selection, Installation & Maintenance Webinar

This Webinar will focus on the different types of variable spring supports and big ton variable spring supports. Learn about the special features available, in addition to the design of a variable support. View how the different coil configurations produce a unique response to an applied load and see how a spring assembly is loaded. Discover the basic steps in selecting a hanger design and the step by step process used to size a spring for your application. Learn about the different attachments, testing, and installation and maintenance procedures. View examples of failed supports provided by our Field Service Division and learn why they failed and how to prevent it. Gain knowledge of the valuable tips used when deciding to replace or re-calibrate a variable spring support, as well as adjustments, shutdown and isolation procedures.

Big Ton Spring Supports Designed for an LNG Facility in Australia

These big ton variable spring assemblies were custom designed for an LNG plant in Western Australia. They are specially designed with PTFE, 25% glass filled slide plates, and will be used under horizontal pressure vessel saddle supports. The big tons were selected due to a combination of heavy loads and thermal expansion. The units measure 30″ x 30″ and are capable of supporting a load up to 95,000 lb. with down travel of 2 to 5mm vertical.

Custom Sway Strut and Pipe Clamp Assemblies for an LNG Plant in Australia

PT&P fabricated and designed 52 of these custom sway strut assemblies for a liquid natural gas plant in Australia. These are manufactured from carbon steel with 304 stainless steel pins. The pipe sizes range from 2”-72” diameter, with a total length ranging from 27” to 137”. The sway struts are fabricated to restrain either tensile or compressive force in one direction while providing for movement due to thermal expansion or contraction in another direction. These sway struts have an operating temperature of 650°F and are designed for operating loads ranging of 650 lb. to 120,000 lb.

G-Type Variable Spring Supports Designed for an LNG Facility

PT&P designed these G-Type variable spring support assemblies for an LNG facility in Saudi Arabia. The variables are comprised of two standard spring housing joined together with an intermediate bridge assembly. They are designed an upwards travel range of 0.078″ to 0.118″. The variables were fabricated from carbon steel with a hot-dipped galvanized finish. Standard load and travel testing was completed prior to shipment.
