Variable Spring Supports for a Gas Storage FacilityVariable Spring Supports for a Gas Storage Facility

A total of 90 variable spring supports were designed and manufactured to support pipe lines in a gas storage facility in Abu Dhabi. The pictures above show PTP-4 Double Spring B-Type, PTP-6 Triple Springs B-Type, PTP-1 Triple Springs D-Type, and PTP-4 Double Springs F-Type, (also known as F-Cans). Load capacities range from 1,000 lb. to 45,000 lb., and movements range from 3/8″ to 3″. A two-layer custom paint was applied over the hot-dip galvanized finish to protect against a severely corrosive environment. Travel stops were chained to the spring can housing, so they can be reused during plant shutdowns. Load and quality assurance tests were performed on all the supports prior to shipment.

Custom Designed Variable Spring Supports with Stainless Steel Slide Plates

Custom Designed Variable Spring Supports with Stainless Steel Slide Plates

This custom designed variable spring assembly is comprised of a standard PTP-1-160 type F variable spring with a supplementary extension and load flange with a stainless steel slide plate. The variable is fabricated entirely from carbon steel with a hot-dipped galvanize finish. The extension is schedule 40 pipe, 8″ in diameter and 12-5/16″ in height. The slide plate is fabricated from A240 grade stainless steel and is welded to the top of the load flange. This support will be used underneath a 16″ diameter pipe with a dummy leg. It is designed for 1/16″ vertical travel and 1/8″ horizontal travel for an oil refinery in Algeria.

Constant Spring Supports Designed with Special Lugs for Connecting to a Trolley

These PT&P 200 series constants are fabricated from A36 carbon steel. The 200-A constants measure 18.5″w x 20″H x 65″L and will support a 22,200 lb. load. They are modified to avoid interference with the structure by shortening the frame. The 200-C constants measure 18.5″w x 29″H x 80″L and will support a 32,000 lb. load. The constants have specially fabricated lugs to allow for a 3 ton trolley to connect with it.

G-Type Variable Spring Support Assemblies for an Expansion Project at an Oil Refinery

March 14th, 2011 No comments

G-Type Variable Spring Support Assemblies for an Expansion Project at an Oil Refinery PTP-2 Type-G variable spring support assemblies were designed and fabricated for an expansion project at an oil refinery. The G-type spring is comprised of two standard variable spring housing-coil subassemblies joined together with an intermediate bridge assembly. The bridge assembly is customized to match existing site conditions, which allows for use in applications with limited space or interferences. This particular assembly was provided with extra large channels because the specified C-C dimension of 59″ exceeded the maximum (48″) of our standard G-type variable springs. The housings, internal components and channels were fabricated from carbon steel, and spring steel was used for the coils. The assembly was designed for a total operating load of 24,014 lb. with a design travel of 0.76″ upward.

——————————————————————————————————————————

A “U-Type” and 6 “C-Type” constant spring supports were designed to support piping in a corrosive environment located off-shore in Malaysia. The U-Type measures 21″ x 25″ x 57″ and C-Types range in size from 11-5/8″ x 17″ x 4″ to 18-3/4″ x 32″ x 80″.

Constant Spring Supports with Corrosion Resistent Coating

The constants are fabricated from A36 carbon steel with a fluorocarbon coating on the pins. The frame, housing, and all components were coated with a 3-coat paint system to resist corrosion. Standard load and travel tests were performed prior to shipping the constants on a rush basis.

F-Type Variable Spring Supports

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.
