Over 400 Clevis Hanger Assemblies Designed for a Pulp and Paper Plant

PT&P supplied over 400 clevis hanger assemblies for a pulp and paper plant in Indonesia. The assemblies accommodate elevation differences ranging from 94-1/2″ to 138″ with pipe diameters ranging from 1″ to 24″ and a rod diameter range of 3/8″ to 1-1/4″. All components were fabricated from hot-dipped galvanized carbon steel and are designed for ambient temperatures and loads ranging from 700 lb. to 7500 lb.

Upcoming Webinar: Compact Spring Support

March 24th, 2016 Comments off

This webinar is over, view the recording at: http://info.pipingtech.com/compact-spring-support-webinar

PT&P partnered with Disc Spring Technology (DST) and is now manufacturing the compact spring support.

Disc SpringsThe Compact Spring Support Webinar will cover key objectives, background and leading industry problems related to process equipment nozzels (both rotating and non-rotating equipment). First we will review the challenges involved in design and analysis of piping with respect to process equipment nozzles. Secondly, we will discuss the types of chronic problems and failures related to process equipment nozzles and present (or introduce) the Compact Spring Support as a solution. During our discussion, we will explain why chronic problems with process equipment exist, describing current design practices as they relate to industry code standards and how the Compact Spring Support addresses these problems directly and effectively. And finally, we will take a quick look at DST technical data and sizing program.

Big Ton Spring Supports Designed to Support a Pressure Vessel in an LNG Facility in Australia

These big ton spring supports were custom designed for an LNG plant in Australia. These units were designed with PTFE, 25% glass filled slide plates, and will be used under the saddle supports of a horizontal pressure vessel. The big tons were selected due to a combination of confined space, heavy loads, and thermal expansion. The units measure 28-3/8″ x 25-3/8″ x 13” and are capable of supporting a load up to 11,488 lb while accommodating a down travel of 0.31 inches.

Constant Spring Supports Designed for a Power Plant in New Mexico

PT&P fabricated constant support assemblies for a power plant in New Mexico. The constant assemblies will be used in conjunction with structural supports also provided by PT&P. Operating loads range between 7,000 lb. and 20,000 lb. and designed for movements from 10-1/2″ to 12″. All thread rods were coated with rust prevention compound and the constants were painted with Intergard® 475 HSS. The travel stops are wired to the constants frame and can be reused to lock the constant, preventing travel during plant maintenance or shutdowns. Standard load and travel tests were completed according to MSS standards prior to shipment.

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.
