May 16, 2011

Pig Launcher and Receiver with a Flag Indicator

PT&P’s Sweco Fab division designed and manufactured a pig launcher and receiver with a flag type  indicator and a flanged HI-T Pig Alert pig signaler. They are fabricated from carbon steel with a three coat paint system. The pig launcher has an 8” diameter minor barrel, a 10” diameter major barrel, and is 110” in overall length. The pig receiver has a 10” major barrel, a GD II Closure and is 170” in overall length. They are designed for 430 psig at 100°F and were hydro-tested at 645 psig , held for four hours. Both pig launcher and receiver went through a 100% radiography test prior to shipment.

Pre-Insulated Pipe Supports with 12" Thick Insulation Designed for a 49" High Temperature Line
April 18, 2011

Pre-Insulated Pipe Supports with 12" Thick Insulation Designed for a 49" High Temperature Line

PT&P fabricated pre-insulated pipe supports from galvanized carbon steel designed for a 49″ diameter pipe and temperatures in excess of 1600°F. The insulation is 12″ thick and composed of lime, silica and reinforcing fibers. This type of insulation features exceptional strength and extremely low water absorption. It is essentially dust-free, contains no asbestos and is a very good material for structural insulation inserts. This “hot shoe” will be used in a cat cracker unit at a refinery in Alabama.

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.

Do you have a need for constants in a current or upcoming project? Let us price them for you! access-our-webinar-archives

Custom Elevated Pipe Shoe-Clamp Supports Designed for a 12" Diameter Transfer Line in a Polymer Plant
March 28, 2011

Custom Elevated Pipe Shoe-Clamp Designed for a 12" Diameter Transfer Line in a Polymer Plant

PT&P designed and manufactured custom elevated pipe shoe-clamp supports for part of a palletizer transfer line in a polymer plant. The custom supports were designed to prevent cracking in the welds and grout base due to severe vibration in the line. The assemblies have an overall height of 48″ with an adjustable load column. The clamp-shoes are 13″ wide by 14″ long, and designed for a 12″ diameter aluminum pipe. The assemblies are carbon steel with a hot-dipped galvanize finish and include a unique laminated vibration dampening lining for the clamp.

G-Type Variable Spring Support Assemblies for an Expansion Project at an Oil Refinery
March 14, 2011

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.
