Cold Shoes with a Load Capacity of 75,000 lbs

PT&P recently designed and manufactured over 1,000 Coldshoes for an LNG Plant in Egypt.  These shoes are designed to support loads up to 75,000 lbs. at an operating temperature of -350°F. They are customized to fit pipe sizes of 20”, 24”, 30”, and 36”. All Coldshoes are composed of stainless steel with a Micarta® insulator.  Micarta® is a woven glass fabric laminated with epoxy resin. It is extremely high in mechanical strength, has low moisture absorption and dissipative factors, and has superior electrical characteristics which are exhibited over a wide range of temperatures and humidities.

Two 15’-0” long Carbon Steel Sway Struts for a Cycle Unit Project

Sweco Fab recently designed and manufactured two carbon steel sway struts with 2” adjustment capabilities for a cycle unit project. The sway strut is constructed of an 8” diameter pipe, 130 ¼” long, assembled with rod ends and brackets for an overall assembly length of 15’-0”. The 2” adjustment capability is accompanied by a load capacity up to 128 KIPS. Sway struts are used to restrain movement of piping in one direction while providing movement from thermal expansion or contraction in another direction.

PT&P Aids in the Immediate Replacement of over 160 Pipe Shoes

PT&P Aids in the Immediate Replacement of over 160 Pipe Shoes

PT&P Aids in the Immediate Replacement of over 160 Pipe Shoes

PT&P was called on by an energy center in Oklahoma to inspect failing pipe shoes designed for temperatures ranging from 650 to 1065 °F supplied by another company.  After thorough inspection, PT&P’s field service representatives concluded that the problem was due to the existing pipe clamps’ inability to firmly grip the pipe during expansion. This exposed the pipes to atmospheric moisture, resulting in both heat loss and deterioration. To alleviate the situation, PT&P designed secured pipe clamps that were bolted and torqued such that the entire pipe shoe would move with the pipe’s expansion. PT&P’s field service team also provided on-site installation of the replacement pipe shoes. The entire process involved stripping of the existing damaged insulation, removal of the failing supports, and installation of new pipe shoes and insulation.

PT&P Aids in the Immediate Replacement of over 160 Pipe Shoes

Pipe Shoes in the Field

Over 160 pipe shoes were engineered, manufactured, and installed for this energy center. The fabricated pipe shoes, designed for pipe sizes ranging from 12 to 28″ in diameter, are equipped with special base plate and slide bearing plate combinations which allowed axial movement from 1/2″ to 7″ and lateral movement up to 10 1/2″. In addition, they were designed to support a maximum vertical and lateral load of 38,000 lb. and 7,600 lb. respectively.

Emergency Request for Types B & E Stainless Steel Constants

Emergency Request for Types B & E Stainless Steel Constants

Within a two-week span, PT&P designed and fabricated eight Stainless Steel, grade-304, types B & E Constants for a marine plant. These constants have a travel of 1 1/2 – 5″ and are specified to carry 50 – 1540 lbs load. Stainless steel was requested due to the corrosive nature of the environment. PT&P also manufactured nine Carbon Steel types B & E Constants for this project.

28" dia. Hotshoes for a Natural Gas Plant

Piping Technology & Products, Inc. recently designed and manufactured twenty 28″ dia. Hotshoes (high temperature pre-insulated pipe supports) for a natural gas plant in Massachusetts. These supports are assembled with a 5″ thick high-density Calcium silicate insulation layer, in addition to stainless steel, Kaowool, and PTFE, 25% glass filled, slide plate materials. The supports are designed to support loads from 25 kips-50 kips at an operating temperature of 1800 degrees F. The shoes also allow for a travel of 7″ where applicable. PT&P also designed and fabricated rod hangers with variable spring supports for this project.

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.

 17,000 lbs. Upthrust Constants for a Construction Site

17,000 lbs. Upthrust Constant

Piping Technology & Products, Inc. designed and manufactured sixty nine Upthrust Constants for a construction site in Chad, Africa.  They range in constant size from 31-61 and are composed of A36 carbon steel. The applicable loads and travel for these constants are from 1,700 lbs.-17,000 lbs. and 3”-8”, respectively. The installed height for this job was much higher than our standard constants, so we had to customize them. By extending the height of our standard constant with an additional angle we were able to meet the installed height.

Variable Springs with Permanent Adjustment Travel Stops

Variable Springs with Permanent Adjustment Travel Stops

Piping Technology & Products designed and manufactured these variable springs with permanent adjustment travel stops for a refinery in Texas.

These types of travel stops are used to allow ease of installation, provide a means for field load adjustment within the working range of the spring, and allow the springs to be “locked” easily whenever they are taken out of service for shutdowns or refurbishment of the system.

For this requisition, a total of 23 variable springs with adjustable travel stops were fabricated.  The springs are made from carbon steel and the adjustment rods are made from A-325 high strength bolt material.  The springs ranged in size from PTP-1-60-F to PTP-2-180-F size spring.  The largest springs were set for an operating load of 12,900 lbs. and a hydrotest load of 14,000 lbs. and a maximum travel of ½.  All of the springs were tested in the load cell to insure proper operation. Per the customer’s request, these springs were supplied at an expedited delivery of 3 weeks.
