240 Welded Eye Rods for an Ammonia Plant

Piping Technology and Products, Inc. designed and manufactured 240 PT&P Figure 110 welded eye rods for an ammonia plant in Saudi Arabia. The rods will be attached to Type A variable springs designed to support loads from 850 lb. to 13,300 lb. Manufactured from A-36 carbon steel, the rods are 3/4 to 2 in diameter and range in length from 68 to 95. To prevent contamination at high temperatures, a red oxide primer with an alkyd topcoat was applied to the rods as per the customer's request. Prior to shipment, a 100% dye-penetrant test was performed to ensure quality.

230 lb. Double Cable Clamp for an Oil Refinery

Piping Technology and Products, Inc. recently fabricated a 230 lb. double cable pipe clamp assembly for an oil refinery in Kentucky. This cable clamp assembly, fabricated from 304 stainless steel, consists of a double clamp, a steel support structural, and a base plate. The double cable clamp with an overall dimension of 22 x 12 x 6 is designed for a 2.4 and a 3.8 dia. armored cable.

Embed Plates for a Concrete Reinforcement Application

Embed Plates for a Concrete Reinforcement Application

PT&P designed and manufactured two 240" x 12" x 1/2" Embed Plates with 3/4" diameter weld-stud projections to be used in a concrete reinforcement application.  All components are fabricated out of carbon steel with a hot-dipped galvanized finish. The plates were shaped to form a 45" x 90" frame prior to shipment. The frames were braced with 2" x 2" x 1/4" angles to ensure the frame maintained its structural shape prior to installation.

950 lb. load C-type Constants

PT&P recently designed and manufactured sixteen PTP-200 C-type constants modified to fit in constricted areas near a furnace of a chemical facility.  These constants are designed to travel from 5 1/2” to 19” and are specified to carry loads ranging from 245 to 924 lbs. They were fabricated from A36 plates with 4140 pins. Due to the proximity of the pipes and other equipment, the front part of the constant frame was cut to allow the pipe to move freely. Load and travel testing was performed to ensure quality and precise performance.

1,520 Spring Assemblies for a Chemical Plant

PT&P recently manufactured 1,520 PTP-2 and PTP-4 spring hanger assemblies designed specifically for a furnace application. These custom variable springs have welded components as opposed to bolted components found in standard assemblies. Due to the space limitation within the furnace, the spring coils were set in a welded housing which allows for the springs to be closely oriented within a smaller spatial envelope. The pipe hanger assemblies are made from carbon steel, consisting of variable spring, rod, and riser clamp components. Instead of galvanizing, the assemblies were coated with a red-oxide primer due to the high temperature operating conditions of the furnace. This prevents the possibility of molten zinc (from the galvanizing process) contaminating the furnace tubes.

1,520 Spring Assemblies for a Chemical Plant

The springs are designed for loads of 143 to 660 lbs. and for total travel ranging from 3/4 to 2". Each assembly was pre-assembled to ensure free movement throughout the spring’s travel range before welding the bottom closure plate. Prior to shipment, all assemblies were calibrated to determine the exact spring rate and then were set to the customer’s designated cold load position. These springs are then located and installed into the furnace based on the spring rate.

Rotary Valve for a Manufacturing Facility

Sweco Fab, Inc. recently fabricated a M-1318 Rotary Valve Assembly composed of a stainless steel hopper, double reduction gear, drive cover, and a sprocket & chain drive. The valve is powered by a 1/2 hp, 3 phase electric motor. This particular piece will be used in a plastic processing company. Rotary valves can be fabricated in different assembly formations and can be altered based upon customer needs.

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.

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.

 

28" dia. Hot Shoes for a Natural Gas Plant

Piping Technology & Products, Inc. recently designed and manufactured twenty 28" dia. Hot shoes (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.
