PT&P Aids in the Creation of a "Chemical Island" in Singapore

February 8th, 2001 No comments

Piping Technology & Products, Inc. supplied a variety of pipeline products for the construction of a refinery plant on Jurong Island, Singapore. Jurong Island is a man-made island consisting of four petroleum refineries, 30 petrochemical firms, and many more industrial firms to support its existence.

PT&P and U.S. Bellows, Inc. first became involved in this extensive project in May 1998. During this time, PT&P supplied the international construction firm with more than 3,000 cold shoes, 400 slide plates and numerous more spring hangers, constants and fabricated pipe supports. U.S. Bellows, Inc., a wholly owned subsidiary of PT&P, also supplied many of the expansion joints used in the creation of this refinery. This includes three 36″ expansion joints were fabricated and sent to Singapore in October 1999. Two years, 300 jobs, and 670 tons of steel later, PT&P completed the last job for this project in September 2000.

PT&P has extensive experience performing product testing to ensure product quality and dependability. For this particular project a load test was performed on a 60″ diameter cold shoe. By measuring the axial and lateral loads, vertical tension and temperature, PT&P engineers are able to determine its maximum load.

Product testing was also performed on the three 36″ expansion joints provided. The bellows together with the hinge assembly were hydro-tested and a dry nitrogen test between the two plies was conducted to ensure that they would withstand the design pressure. These expansion joints were tested per ASME Sect. VIII Div. 1 Appendix 26 standards.

These supports are key components for the steam generators in a thermal power plant. The coils are coated with neoprene (black) to prevent corrosion while the steel plate and tie rods are painted white. Engineers of Piping Technology & Products, Inc. designed these units to support loads of 110,000 kips.

PT&P Providing Training to Field Personnel

Piping Technology & Products, Inc. shipped approximately 150 pipe supports to the Red Hills Power Plant with radio frequency identification (RFID) chips affixed to each pipe supports.  The RFID tags and RFID handheld reader were provided by SAT Safetrac.  Field personnel were trained on the use of the new technology.  The RFID-tagged pipe support assemblies were then received by field personnel.  Videos of the RFID receiving process were taken for the purpose of comparative time and motion studies.

16,000 Lb. 33 1/2" Travel Horizontal Constant Load Hangers

16,000 Lb. 33 1/2" Travel Horizontal Constant Load Hangers

In January 2000, Piping Technology & Products, Inc., a manufacturer of high quality engineered products, designed and built two 33 1/2 inches travel and two 25 inches travel constant load spring hangers. These constant load spring hangers will be in service at a geothermal production well in Hawaii, where they will be used to support a pipe that carries hot water discharged from a geothermal production well to a separator.

16,000 Lb. 33 1/2" Travel Horizontal Constant Load Hangers

The well will produce 2.8 Million gallons of water per hour at a discharge temperature of 680° F, and a pressure of 2800 psi. These custom designed constant load spring hangers provide extraordinarily large travel distance. The 33 1/2″ travel and the 25″ travel constant load spring hangers are designed to provide a constant 16,000 lbs. and 6,000 lbs support for a pipe moving a vertical distance of 33 1/2″ and 25″ respectively.

Replacing a Spring Coil With Stainless Steel Bellows

October 21st, 1997 No comments

Spring coils are so pervasive in design of pipe supports that our collective paradigm limits our ability to consider alternatives. The photograph below shows an example of a pipe support designed for the special environment of an off-shore platform which uses a stainless steel metal bellows instead of a spring coil.

This customer was concerned about the corrosive environment and the salt water which will occasionally flow over the pipe support. The rolled plate on the left will be welded to a structural pipe on the platform. A riser clamp (not shown) will be attached on the right. The stainless steel bellows was designed with the proper spring rate and movement.

Testing Proves Spring Coils Will Function In a Hot Environment

August 15th, 1996 No comments

An engineer with a major Houston E&C firm had concerns about the effect the temperatures in the furnace his company was designing would have on the coils in the spring supports used to support the tubing. PT&P engineers put the same question to the major suppliers of coils in the U.S.A. No one seemed to have the data to prove the coils would withstand the temperatures. The E&C firm included a requirement to test for relaxation of the coils with their purchase order to PT&P.

A random sample of coils of the size required was selected from PT&P’s inventory. The loads required to compress the coils through ten inches of travel were recorded and the coils were placed in a furnace at a controlled temperature of 176 degrees F for forty-eight hours. After the coils were cooled they were again compressed. No difference in the loads required was observed.

We did not expect any relaxation of the coils, but it was nice to have the experimental data to back our judgment.

Specially Designed 120,000 lb Load Big-Ton Spring Supports

Pictured above are Big-Ton Spring Supports specially designed by Piping Technology & Products, Inc. These types of supports are used in supporting large and heavy units such as compressors, vessels and pumps in power and petrochemical plants. The ones below were used to support vessels in excess of 120,000 pounds. The Big-Ton Spring Support are designed to allow limited movement in confined areas. By doing this, it saves the customer from having to entirely redesign the piping system and saves thousands of dollars.

Specially Designed Upthrust Constants

Specially Designed Upthrust Constants

Piping Technology & Products, Inc. announces the latest design of their “Horizontal Upthrust” base type constant support. The table or load flange move straight up or down as the weight of the pipe is transferred to the helical coil (spring) via the internal camlinkage. PTFE, 25% glass filled, slide bearings on the four corners eliminate the possibility of binding if undue axial or lateral forces are exerted. Also, PTFE, 25% glass filled, or graphite slide bearings can be added to the table to ease movement along the axis of the pipe. The Big-Ton and Type F Base Constant Supports are still available for other applications.]

Constant Effort Supports in the Field

Piping Technology & Products, Inc. has designed and built thirty-two constant effort supports ranging in loads from eighty to eighty-seven kips with seven and one half inches of total travel on each.Six of the thirty-two are shown in position and they will support critical portions of the heater. The balance in other parts of the plant will support equally critical lines such as main steam and boiler reheat.

Located near Calvert, Texas, this is the second generating facility for Texas – New Mexico Power at this site. Piping Technology & Products, Inc. supplied the same material on the previous installation for this client.

Constants for a Radiant-tube Support System

The photograph above shows a large number of specially designed constant spring supports being prepared for shipment to Chile. These constants are the key component of a reforming furnace, radiant tube support system designed for one of the world’s major engineering and construction firms.

Piping Technology’s engineers designed these units to fit in the limited space available inside the furnace and provided optional bolting patterns so attachment to the supporting structure could be made even if the radiant tube support system assumed a competitor’s design.
