Spray Nozzle Assemblies for a Special Pressure Application

Sweco Fab. Inc. recently manufactured 16 injection spray nozzle assemblies from INCO 625 material for a specific pressure application.   Each nozzle is made up of a 1½ S/160 pipe. The quill construction is clog proof and utilizes the turbulence created by its unique design to achieve distribution of the injected liquid into the product flow.

8,500 lb. Load Pipe Clamp Support Assembly

PT&P recently designed and manufactured a support assembly with two PTP-2 Type C spring hangers and a special clamp support. The springs are designed for an 8,500 lb load and a maximum travel of 1″. The entire pipe hanger assembly, with a net weight of 860 lbs, was fabricated from Carbon Steel and A-387 GR. 22 Chrome. The springs were calibrated to determine the exact spring rate prior to adjusting to customer specifications.

Custom Carbon Steel Anchors and Shoes

Piping Technology and Products, Inc. fabricated 4702 carbon steel pipe shoes for various pipe sizes ranging from 2” to 10”. As per customer request, the shoes are designed to accommodate 30 PSI compressive strength. A three-coat paint system was applied for corrosion protection. All supports were liquid dye-penetrant tested at 5% of welds.

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.

 

150 PSIG Heat Exchanger for a Chemical Process Research Lab

Sweco Fab., Inc. recently designed and manufactured a 1 1/2" diameter heat exchanger for a chemical process research laboratory.  This Heat Exchanger is fabricated from stainless steel, grade 316L, with a maximum allowable working pressure of 150 PSIG at 250°F. It was hydro-tested at 185 PSIG. Heat exchangers are widely used in refineries for multiple applications. Sweco Fab, Inc. can design and fabricate pipe supports and heat exchangers in different sizes and materials as per customer needs.

PT&P Provides Variable Springs to an Oil Refinery

Piping Technology & Products, Inc. has designed and manufactured over 177 tons of supports for the Chad/Cameroon Development Project in Chad, Africa. Adjustable Base Pipe Supports designed to support pipe size ranging from 3 to 18" in diameter were one type of the many supports fabricated for this project.

Each of the hot-dipped galvanized pipe stands (pictured at left) has an 8"x8" base plate and a midrange height of 12". The pipe stands allow for a maximum travel of +/- 3". These supports provide for easy adjustment in the field when supporting pipe trunnions on concrete pads or foundations. In addition, these pipe stands have a major advantage when the exact installation heights are not known at the remote job site.

Other supports including constants and variables spring hangers, rigid rod hangers, structural steel, FRP pads, and pre-insulated pipe supports were also manufactured in a range of different specifications and materials.

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. 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.
