CATALOG 82 ENGINEERING SUPPLEMENT NO.3.STATIC ND DYNAMOC STR INTS DESIGN INFORMATION BERGEN-PATERSON PIPESUPPORT CORPORATION WOBURN, MASSACHUSETTS 01888
Bergen-Paterson markets the widest selection of restraint assemblies and devices which allows the designer to select devices technically and economically suited for the specific application, by type, size and configuration. Bergen-Paterson restraint systems now cover a broader range of load ratings and allow greater flexi- bility in field adjustment. High precision stainless steel ball bushings and pins are now standard components throughout the line. Also included is a new series of restraint yoke clamps. Bergen-Paterson hydraulic snubbers have also been improved and are available with options to better suit the different conditions the application requires. E Specifications : All Bergen - Paterson restraints are designed to meet requirements of: Manufacturers Standardization Society SP-58, Manufacturers Standardization Society SP-69 and ANSI Code for Pressure Piping ANSI B31.1. Rigid Strut Assemblies RECOMMENDED SERVICE : Used to restrain movement of piping in one direction. Movement due to thermal expansion in other directions should be evaluated. STANDARD DESIGN FEATURES: Designed to restrain tensile and/or compressive forces. Tight fitting connections allow positive control of piping systems. Hydraulic Snubber Assemblies GENERAL APPLICATION: Used for the control and protection of piping and equipment subject to shock (impulse) loading and swaying (cyclic) conditions. Its use transfers any imposed forces on the piping or equipment directly to the building structure at the instant of shock occurrence, while at all other times allowing free unrestricted movement through its normal operating range. SPECIFIC APPLICATIONS: Earthquake protection. To prevent damage by wind in outdoor installations. Employed at points in piping systems subject to shock loadings generated by quick closing valves, water hammer, relief valve reaction or other applied shock loads. STANDARD DESIGN FEATURES: Piping and/or equipment movement is controlled by tamper-proof dual stage flow control poppets designed with self cleaning orifices. Furnished as a complete, compact, and efficient unit, ready for immediate use. Manifold configuration requiring no external piping. Ethylene-propylene (EP) elastomer seals. Spherical, self-aligning ball bushings allow for ± 50 of angular motion or misalignment. Hydraulic fluid - General Electric SF1154 Methyl Phenyl Polysiloxane Silicone Fluid. Pressurized hydraulic reservoir allows mounting in any spatial orientation. Virtually no resistance to normal thermal movements of the piping. 7 Copyright 1982 Bergen-Paterson Pipesupport Corporation, Boston, Mass. 1 Units meeting the requirements of the ASME Boiler and Pressure Vessel Code, Section III are also available in accordance with Bergen-Paterson load capacity data sheets. Spherical, self-aligning ball bushing at both ends of the strut allow for ±5 of angular motion or misalignment. Can be installed in any spatial orientation. Field adjustment is available in all assemblies. All welding work required in the field is recommended to be fillet welds. Paint - Standard primer finish. Paint - standard primer finish. Large restraining forces compared to size. Functions in restraining tension and compression. Designed for continuous operation at 200 F with brief transients to a maximum of 350 F. Seals and fluid have been tested to a cumulative gamma dose of 3 x 107 rads without impairment of operation. Stroke determination is made from built-in datum point located on piston rod. Fluid Level Indicator - Provides concise determination of exact fluid level in the unit, thereby eliminating estimate of reserve fluid level. OPTIONAL DESIGN FEATURES: Stroke Position Indicator - A striped piston rod is available for "at-a-glance" determination of stroke position. Integral Relief Valve - A non-adjustable valve, which is factory preset at 133%, or 200% of rated load. Activation indicator - At 100 psig or greater, a pop-up device indicates that the unit is restraining load. Must be ordered with optional integral relief valve. Rigid Strut Application - When no thermal growth is anticipated after lock-up an optional poppet valve, without bleed, is furnished. Must be ordered with optional integral relief valve. More detailed information and brochures concerning the Bergen-Paterson Snubber are available upon request from your nearest Bergen-Paterson sales office. Dimensions subtect to change wlthoutnotlc.

Restraint Pipe Clamps Part 6520, 6525 Part 6521, 6526 LOAD i /x.10 trrf) Part 6520, 6521 SIZE RANGE : 700 to 1500 pounds of force in various pipe sizes from 1/2 through 21/2 inches. MAX. TEMP.: 350 F (11/2" insulation max.) Part 6525, 6526 SIZE RANGE : 700 to 1500 pounds of force in various pipe sizes from 1/2 through 21/2 inches. MAX TEMP.: 650 F (21/2" insulation max.) MATERIAL: Carbon steel except the load pin which is stainless steel. SERVICE: For non-integral on-axis attachment to the piping system in restraint applications. FEATURES: Designed for use with spherical ball bushings. Tight tolerances provide for low lost motion. Interchangeable with a variety of Bergen-Paterson struts. INSTALLATION NOTE: Torque u-bolts to 15 ft.-lbs. (nominal). Then lock jam nut to full nut. PIN ORIENTATION : Parts 6520 & 6525 are perpendicular to pipe center line. Part 6521 & 6526 are parallel to pipe center line. NOTE: This clamp is designed to function within a 10 cone of action perpendicular to the pipe. Loading beyond this cone is not recommended. USED WITH : Bergen-Paterson parts 2015, 2250, 2252, 2525, 2530. ORDERING: Specify part number, load size, and pipe size. Part 6520,6521 ( 11/2 "Insulation Max.)
