Sweco Fab, Inc. recently designed and fabricated 58 floating rings for a Refinery in Saudi Arabia. Ranging from 40″- 155″ in diameter and 12″- 18″ in height, these rings weigh more than 1,500 lbs. each and are made from SA240-316H stainless steel plate with thickness of 1/2″ – 1 1/2″. All rings are fabricated by Full Penetration Weld and examined by dye penetration test.

Piping Technology & Products recently designed and manufactured four fig. 2100 hydraulic shock snubbers for a refinery in California. Carbon steel was used to manufacture these snubbers. They support a maximum load of 14,000 lbs., have a 3” cylinder, and 5” stroke load. This was a custom job where the customer provided the figure number, cylinder size, and stroke load; we built the snubbers according to these specifications.

Piping Technology & Products, Inc. recently designed and manufactured 200 U-Type upthrust constants for a geothermal plant in Hawaii. The constant pictured on the left has frame dimensions of W 40″ x H 75″ x L 142″, a constant load of 9,888 lb. to 10,239 lb. and a design travel of 46″. It also utilizes rollers and PTFE, 25% glass filled slide plates to reduce the friction resulting from axial movements. All the constants in this project are composed of A36 carbon steel. Standard load testing and travel testing were conducted prior to shipment.

The three pictures above show materials being crated for shipment overseas. At the top center are pallets of variable springs designed for 10” of movement and 1000 pound load. This unusual combination of requirements is satisfied by an unusually long coil. This project required 700 of these variables. At the bottom center are constant supports designed for 14” of movement with loads near 2000 pounds. This large movement, unusual for this load, requires the large arc seen in the frame of the constant body. Two hundred of these constants were required. These spring supports are painted with a shop prime.

Piping Technology & Products, Inc. recently designed and manufactured 46 of these support assemblies for a cross-generating power station in South Carolina. These pipe shoes and assemblies are composed of carbon steel and accommodate pipe with diameters ranging in size from 18”-32”. All of these components are strong enough to support maximum installed loads of 8,000 lbs.

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.

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.

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.

Piping Technology & Products, Inc. recently designed and manufactured Sway Struts, PT&P Fig. 2110, with clamps for a construction company in Indiana.
The overall length of the support assemblies range from 24” to 60” and have loads ranging from 3,500 to 11,630 lbs. The strut assemblies are made of carbon steel and are used to restrain movement of piping in one direction while providing for movement due to thermal expansion or contraction in another direction.

Piping Technology & Products, Inc. designed and manufactured these Fig. 1400 pipe shoes for a power plant in Canada.
These Fig. 1400 pipe shoes are a combination of PT&P Fig. 900 and 400. These shoes are particularly made from carbon steel and graphite with 4” B.O.P (bottom of the pipe). They are used to control pipe movement by guiding. These shoes also prevent vertical and horizontal movement and allow axial movement. They are mainly used in power plants or areas where there is cyclical filling and emptying of the pipe.
