Big Ton Springs used in a Chemical Processing Plant

Stainless Steel Slideplates on Big Tons

The limiting constraint in designing and fabricating these big ton spring supports was to maintain an overall height less than 15-3/4″ and still allow the load table to travel downward during operation. Whereas a standard PT&P size 2-190 variable springs would have been sufficient to hold the load specified, the coil alone was taller than the space available at site. For this reason, a “big ton” design was implemented which utilized six smaller coils (2-130 size) working in parallel to produce the required load-carrying capability and spring rate.

All of the frame/housing components were made from carbon steel and supplied with an HDG finish. The travel stop rods were made of A-193 Gr. B7 material and were painted red. The slide plates sitting atop the load flange were made of polished A-304 stainless steel.

Both “big ton” assemblies are 30″ wide by 30″ deep by 15-3/4″ tall. Overall spring rate is 3,600 lb/in. and each weighed approximately 1,460 pounds. The installed (cold) load = 14,800 lbs. and the operating (hot) load = 16,075 lbs. Movement from cold to hot = 0.354″ down.

Tested in the load cell to insure proper operation throughout the entire working range of the coils, the “big tons” were then set to the cold (installed) load as specified.

60 Bolt Cradle Supports

Piping Technology & Products, Inc. custom fabricated sixty bolt cradle supports in May 2006. The base was fabricated by welding two plates to form a “T.” This was used in place of a standard split “T.” By making simple modifications to a standard Figure 900 for two-inch pipe, such as heavier clamps and shortened base length, PT&P was able to meet the customer’s special requirements quickly and efficiently.

Hot Shoes for a Power Plant in Argentina

Hot Shoe Inspection

Piping Technology and Products, Inc. received an order for a power plant in Argentina from our Pipe Shields division. This order consisted of variable assemblies, constant support assemblies, sway struts, and pre insulated pipe supports. Pipe sizes supported were up to 42” with 3” of insulation ranging from 340 lb. to 1300 lb. All hot shoes were designed to carry the load, along with its own weight and insulation. Since these pre-insulated supports are used for high temperature pipes, PT&P used calcium silicate as insulation and hot dipped galvanized the steel as a rust inhibitor. Piping Technology and Products Inc. handled all logistics of the international shipment.

Anchor Bolts for Boiler Feed Water Pump Turbine Drives

Anchor Bolts for Boiler Feed Water Pump Turbine Drives

These are special high-strength anchor bolts used in a coal-fired power plant to secure the water pumps’ foundation. They range from 1” to 3 1/2” in diameter and 137” in length. The actual bolts are made from ASTM low Alloy Steel F1554-04, grade 55. This steel has a tensile strength of 517-655 Mpa, (75-95 Ksi), and a yield strength of 380 Mpa, (55 Ksi). The nuts are made from ASTM A563, grade A, and the washers from ASTM F436, Type 1. The bolts are threaded per UNC threading, class 2A fit, and the finish is plain.

100 Type F Vertical Constant Supports

100 Type F Vertical Constant Supports

These are constants known as 100 type F vertical constant supports. They support pipe from below by means of a sway strut. They are fabricated from A36 carbon steel and hot dipped galvanized to prevent rusting. The constant in the first picture maintains a constant load of 7,000 lb. while the constant in the second picture maintains a load of 9,000 lb. on the pipe throughout its 4” of total travel. They are 36” high with two gussets at the base plate to prevent the coil housing from collapsing under test loading and normal operation. Standard load and travel testing was performed on the constant to insure proper field operation.

80ft. wide Cantilevered Canopy for an International Project

80ft. wide Cantilevered Canopy for an International Project

Piping Technology & Products, Inc. fabricated a Cantilevered Canopy for the entrance of an International State Department building. The Canopy was fabricated using ten 20-foot long girders. These girders were connected by sixty-three structural steel members. Together, they formed the 80-foot width of the Canopy. The wooden sheathing and architectural cladding that is supported by the canopy’s inner steel structure was installed at the construction site.

The fabricated girders and structural members combined weight exceeds 33,000 lb.

Piping Technology & Products also supplied the steel framing that supports the sheathing and cladding, roof drains and piping installed inside the canopy.

Close-Up View of MegaLug

Piping Technology & Products, Inc. and its wholly owned subsidiary, Pipe Shields, Inc. designed and fabricated many structural pipe hangers for an on-going project to rebuild the San Francisco-Oakland Bay Bridge. The pipe hangers are made out of A-36 carbon steel and galvanized to withstand corrosion from the ocean waters and rough winds. These pipe supports will be welded to Pipe Shields’ C Model Anchor Plates, which are set in a cast concrete to the bottom cavity of the bridge.

Structural Pipe Hangers

Supports pictured utilize friction holding devices known as MegaLug®, which permit attachment to the pipes without welding. These supports were designed and fabricated to include improvements in regard to strength and durability to withstand high loads during earthquakes and other seismic events.

Variable Springs for a Project in Mexico

Variable Springs for a Project in Mexico

Close Up of G-can

This Type G variable spring was manufactured for a Petrochemical Plant in Mexico. The Type G assembly is formed by welding two standard spring assemblies to the ends of a pair of channels. This type of assembly can accommodate unusually heavy loads, and is especially convenient for avoiding interference in spaces where headroom is limited.

Each spring assembly is loaded per the client’s specification at Piping Technology and Products manufacturing facilities. A travel stop is inserted and strapped in place to maintain the load for the assembly installation. In addition to banding the travel stops, the variables for this project required chained travel stops. The base style (F-Type) variables on this project were also required to have internal guides.

At Piping Technology and Products, Inc. we use PTP-1, PTP-2, PTP-4, PTP-6 and PTP-8 to designate the five standard coil arrangements to increase the working range of travel of variable supports.

Several types of variable supports were made for this particular project. They included Type A, Type B and Type F.
