20,500 lb Riser Clamps for a Power Plant

PT&P recently fabricated 22 Fig. 190 Type 3 riser clamps for suspending the vertical runs of pipe at the central power plant in Puerto Rico.  The clamps are designed for 17" and 24” pipes and have an overall length of 71" and 87” respectively. Both designs have a bar stock size of 1.75"x10" and load bolts of 2.75" diameter. Utilizing gusset plates at the clamp’s bend radius allowed for the smallest, yet sufficient clamp stock size for the specified loads. The smaller clamp has an operating capacity of 14,000 lbs while the larger operates at 20,500 lbs. Chrome-Moy 387 Grade 22 bar stock was used with A193 Grade B7 bolting to accommodate high temperature operating conditions.

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.

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.

Variable Assemblies with Pre-Insulated Pipe Clamps

Piping Technology & Products, Inc. designed and manufactured several variable assemblies with pre-insulated pipe clamps for a chemical company in Texas. These assemblies are constructed of galvanized carbon steel hangers and hardware with Marinite® insulation.  The fabricated clamps range in size from 10" to 30", insulation thickness of 1" to 8" and with spring hanger sizes 80-180 standard, double, and triple variable spring hangers.

3 Custom Built Disc-Spring Arrestors with Clamps

The disc-spring arrestors provide resistance by utilizing disc springs (sometimes referred to as Belleville® washers) stacked in a series within the assembly housing to produce a specific spring rate.  By utilizing large (over 8 diameter) disc springs, very high spring rates may be obtained.  The arrestors are capable of operating in both tension and compression.

The housing, end bracket, and extension pieces of the spring arrestor are made form A-36 carbon steel. The disc springs are made from ASTM A-1075 spring steel. One clamp (for design temp. of 688 degrees F.) was made from carbon steel and two clamps (for design temp. of 1054 degrees F.) were fabricated from A-387 GR.22 Chrome-Moly steel.

The diameter of each disc spring was 9 with a thickness of 1. The overall pin-to-pin dimension for the assemblies varied with a minimum of 35 and a maximum length of 57. The maximum length that can be accommodated is 120. The clamps were made for 18 and 30 diameter pipes.

The shock arrestor will see a maximum operating load of 43,000 lbs. The spring rate of each arrestor was designed at 40,000 lb./in. The spring arrestors are designed for a maximum displacement of 2. The arrestors were tested to verify spring rate and to confirm the operation of the pipe hanger assembly.

18,500 lb. Load Constants for a Construction Site

The constants are made from A36 carbon steel and range in height from 4'-0 to 5'-0 and C-C dimension of 7'-0 to 8'-4.  They have a load capacity of 12,000 lbs. to 18,500 lbs. and a 4-5 travel capacity. Load setting and travel testing was conducted on the constants to ensure they met the customer's requirements.
