300 Variable Spring Supports Designed for a Furnace Application at a Methanol Processing Facility

300 Variable Spring Supports Designed for a Furnace Application at a Methanol Processing Facility

PT&P designed and fabricated 300 variable spring supports for use in a furnace within a methanol processing facility in Mexico. We manufactured the ”housing” of these variable springs using seamless pipe (in order to prevent the springs’ coils from rubbing against the ”weld seam” of a standard pipe) so that the exact spring rate (+/- 5%) can be calculated without discrepancies or variations. The reason that an accurate spring rate is important is because furnace springs function as a ”scale” in order to determine the weight of the radiant coils within the unit. These springs are coated with red oxide primer to protect against corrosion. We manufactured these furnace spring assemblies for an operating load of 1,036 lb. and a movement up to 8 1/2″. Each spring is traceable to test data and tagged with its’ unique spring rate along with other standard information use for identification.

PT&P partnered with Disc Spring Technology (DST) and is now manufacturing the compact spring support.

Disc SpringsThe Compact Spring Support Webinar will cover key objectives, background and leading industry problems related to process equipment nozzels (both rotating and non-rotating equipment). First we will review the challenges involved in design and analysis of piping with respect to process equipment nozzles. Secondly, we will discuss the types of chronic problems and failures related to process equipment nozzles and present (or introduce) the Compact Spring Support as a solution. During our discussion, we will explain why chronic problems with process equipment exist, describing current design practices as they relate to industry code standards and how the Compact Spring Support addresses these problems directly and effectively. And finally, we will take a quick look at DST technical data and sizing program.

Constant Spring Supports Designed for a Power Plant in New Mexico

PT&P fabricated constant support assemblies for a power plant in New Mexico. The constant assemblies will be used in conjunction with structural supports also provided by PT&P. Operating loads range between 7,000 lb. and 20,000 lb. and designed for movements from 10-1/2″ to 12″. All thread rods were coated with rust prevention compound and the constants were painted with Intergard® 475 HSS. The travel stops are wired to the constants frame and can be reused to lock the constant, preventing travel during plant maintenance or shutdowns. Standard load and travel tests were completed according to MSS standards prior to shipment.

Big Ton Spring Supports Designed for an LNG Facility in Australia

These big ton variable spring assemblies were custom designed for an LNG plant in Western Australia. They are specially designed with PTFE, 25% glass filled slide plates, and will be used under horizontal pressure vessel saddle supports. The big tons were selected due to a combination of heavy loads and thermal expansion. The units measure 30″ x 30″ and are capable of supporting a load up to 95,000 lb. with down travel of 2 to 5mm vertical.

Compact Spring Supports Designed for a Pump Application in Wyoming

November 30th, 2015 Comments off

Compact Spring Supports Designed for a Pump Application in Wyoming

These compact spring supports were custom designed and built within 4 weeks to support a pump for a facility in Wyoming. The housing was fabricated from A-36 carbon steel and hot-dipped galvanized to protect them against corrosion. The disc springs are engineered using the stainless steel Belleville disc springs designed for large loads but small movements. In this case, the springs are designed to support a load of 11,137 lb. and movement of 0.018″ (upward). Each assembly underwent load testing prior to shipment.

The compact size and resistance to corrosion attributes of these compact spring supports make them ideal for placement under the discharge piping of a pump at this facility. By using these compact spring supports directly on the pump, excessive thermal loading on the pump’s discharge nozzle is resolved and brings it within the pump manufacturer’s allowable limit, so the pump will operate safely, as intended which also results in extended life and low maintenance.

Engineered Spring Supports

Learn how the theoretical applications of spring supports are put into use in the real world. We will start with a review of the working principles of both variable and constant springs. See how brand new spring looks at delivery, and review installation guidelines. Learn the key points to review through the total installation process and subsequently when the springs are in operation. See how to determine if springs need adjustments, re-calibration, refurbishment or replacement. View in field examples, shutdown and isolation procedures. See the selection process required when there are significant changes to the operating condition.
