Emergency Field Service Request on Constant

Emergency Field Service Request on Constant

Emergency Field Service Request on Constant

Piping Technology & Products, Inc. and its 24×7 Quick Turn/Emergency Service were put to the test on a Friday evening when they received an emergency call from a company located in Jamaica. The Jamaican company was concerned with existing pipe supports at their location and made a request for a PT&P field services representative to visit and inspect.

An experienced PT&P field services manager arrived at 8:00 p.m. on Saturday to survey and fulfill the request.

The reported problem was a pair of rusted and decayed spring hangers dating back to 1969. After inspection, PT&P’s field services manager concluded that the aged spring hangers could no longer support the piping system due to changes in the design of the system, whereas, failure resulted in additional forces being exerted onto the steam turbine.

Following identification of the measurements, load capabilities, and movements of the spring hangers, it was apparent that the system design did not compensate for the weight of two globe valves that were added to the system at a later date. Thus, PT&P’s field services manager had to take into consideration the weight of these two globe valves when sizing the replacement parts.

PT&P supplied and delivered two Type G variable spring assemblies to Jamaica on the following Monday. Type G assemblies can accommodate unusually heavy loads, and is especially adaptable for avoiding interference in spaces where headroom is limited. In this case, the spring assembly was supporting loads in excess of 2000 lbs. and movement was limited due to its location in the powerhouse.

Replacement of a Constant Spring Hanger

A large refinery plant located in Pasadena, TX called upon Piping Technology & Products, Inc. to aid them in the immediate replacement of a 5400 Lbs, 7 1/2″ travel vertical constant spring hanger used to support a Coker drum.

The constant spring hanger was damaged during servicing. The reliability engineer from the refinery contacted PT&P Wednesday evening to request an inspection by a PT&P field services representative. The following morning PT&P’s field services representative arrived on-site, inspected the damaged constant spring hanger and suggested that a replacement would be most efficient and cost effective. With the existing nameplate bolted to the constant, PT&P was able to easily locate the original design of the constant.

The original design, along with the convenience of the component parts being in stock inventory, allowed PT&P to quickly manufacture a replica of the constant and ship it out on the same day by 6 p.m.

In the past, lead times for delivery of constant supports averaged 6-8 weeks, however, through the process of maintaining stock components of interchangeable parts, lead time has been drastically reduced. Piping Technology & Products, Inc. maintains a large inventory of stocked constant support assembly components that allows them to quickly assemble and ship to customers on demand, especially in emergency/quick-turn situations.

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

February 8th, 2001 No comments

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.

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 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.]
