113 F-Type Variable Spring Cans with PTFE Slide Plates

July 16th, 2012 Comments off

113 F-Type Variable Spring Cans with PTFE Slide PlatesThese F-Type variable spring cans were designed with PTFE, 25% glass filled slide plates for a local oil refinery. Slide plates are used to reduce the friction between the load flange of the spring and the pipe support. This allows for easier adjustment of the spring’s installed height. These variables include external travel stops. The external travel stops are sometimes referred to as universal travel stops and can be utilized to adjust the installed load (also called the cold load) to other installed loads within the working range of the spring. 113 variable springs were supplied for this job. The variables have an installed load ranging from 95 lb. to 11,000 lb. and an operating load ranging from 90 lb. to 10,703 lb. They are part of a plant expansion and will be used to support horizontal piping in an oil refinery.

Big Ton Variable Spring Supports with Rollers Designed to Support a Load up to 60,000 lb.

These are custom designed big ton variable spring assemblies manufactured for a chemical plant in Brazil. They are fabricated from A-36 carbon steel, with monel rods, nuts and hardware. They measure 18″ L x 26″ H x 26-1/2″ W and are capable of supporting loads up to 60,000 lb. with down travel of .52″. These big tons employ the use of rollers for adequate mobility and are painted to protect against corrosion.

232 Variable Spring Supports for a Natural Gas Processing and Separation Plant

A total of 232 variable spring supports were custom designed for a natural gas processing and separation plant. This project included various spring sizes from PTP-1 30 C-type to PTP-4 160 F-type assemblies. The variables are fabricated from carbon steel, galvanized and coated with a special 3-coat paint system to protect against corrosive byproducts such as sulphur. The F-types include 304 stainless steel and PTFE, 25% glass filled slide plate assemblies.

PTP-1 F-Type Variable Spring Assemblies

December 19th, 2011 Comments off

PTP-1 F-Type Variable Spring Assemblies

These PTP-1 F-Type variable spring assemblies fabricated from A-36 carbon steel, were custom designed to accommodate a height of 11-11/16″ while keeping the same spring rate. The F-Type variable is used to support the pipe from below and are typically mounted to concrete pads via anchor bolts or welded to structural steel. The variables are designed for loads up to 6,500 lb. and a total upward travel of 5/16″.

F-type Variable Spring Support with a Stainless Steel Wire Rope Isolator

September 6th, 2011 No comments

F-type Variable Spring Support with a Stainless Steel Wire Rope Isolator

This F-type variable spring support was customized with a wire rope isolator for a facility located in Canada. The variable spring was designed for a load of 12,000 lb. The wire rope isolator is essentially a 1.25″ diameter stainless steel rope looped eight times between two chemically conversion coated aluminum alloy retaining bars. The wire rope isolator is effective in vibration isolation and energy absorption.

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.

Various Variable Support Assemblies for a Power Generation Facility

Various Support Assemblies for a Power Generation Facility

Piping Technology & Products, Inc. designed and manufactured 85 support assemblies for a power generation facility in Georgia.   These assemblies consisted of Variable and Constant Assemblies and structures made with carbon steel and alloy material. The variable spring hanger assemblies have standard three-bolt clamps and lug attachments for the existing pipes. These variable spring hangers accommodate operating loads varying from 8,000 to 18,000 lb. and 1-1/2 ” of upward travel. PT&P also manufactured a Fig.43 (heavy duty yoke u-bolt) for a 14″ diameter pipe. Components of the Fig. 43 include yoke, U-bolt, shield, and lug. The structure (beam, plate, angle, and tube steel) was painted green as per the customer’s specifications.
