What is the purpose of a three bolt clamp?

May 16, 2014

A three-bolt clamp is normally used for horizontal insulated piping, which utilizes clamping bolts to attach the clamp to the pipe and a separate Load Bolt to transfer the piping weight to the remainder of the Pipe Hanger Assembly from a point outside the insulation.

What are cradle clamps?

February 11, 2011

A cradle clamp support refers to a shoe type support which you do not weld directly to the pipe but rather use a bolted configuration instead of a welded configuration.

42” Hold Down with Wedge Support
42” Hold Down with Wedge Support

PT&P designed and fabricated a Hold Down with wedge support for a 42” pipe. The entire assembly is PTFE, 25% glass filled, bonded and will be used to control and reduce pipe vibration at an LNG plant. Both the Hold Down and wedge support are made from A36 Carbon Steel and a fabric pad which is exceptionally suited for vibration impact and declination.

The clamp attachments shown are used for supporting vertical pipe sections to vessel clip anchors. These braces are designed for a maximum horizontal moment of 15,000 ft-lb at the vessel clip. All the clamps provided were made of carbon steel with a hot-dip-galvanized finish. The pipe hanger assembly lengths were fabricated per specifications provided by the client.

The clamp components were designed and fabricated for non-standard pipe diameters (i.e. 13-3/4″, 16-1/2″) so that they could be used on insulated or finned pipelines.

24", Chrome-Moly, Three-Bolt Clamps with Stanchions

Piping Technology & Products, Inc. designed and fabricated 24″, chrome-moly, three-bolt clamps with horizontal guide stanchions for a 765 MW natural gas-fired combined cycle facility in Mexico.

These clamps, in conjunction with variable springs, will allow for vertical and axial pipe movement while restricting lateral movements. They were made for 24″ OD pipe from 1-1/2 x 9″ stock material. Based upon design considerations, the clamp “E” dimension, from pipe centerline to outer load bolt, was 25″. The clamps were designed for operation at 1065°F and per customer-supplied information, the vertical design load was 1,848 lbs and the maximum lateral load was 19,207 lbs.

The clamp plates are made of A387 GR. 22 plate material, stanchion pieces of A335 GR.22 pipe and the side stop plates of carbon steel.

Piping Technology & Products, Inc. custom designed and fabricated a 66-inch diameter, three-bolt pipe clamp for a chemical company located in Deer Park, Texas.

The clamp will be used in conjunction with a PT&P Spring Hanger and a length of rod in order to support the pipeline.  After formation, the clamp’s dimensions measured at 97.75 OAL and 69.5 at its widest point. By using a FEA program, the clamp was designed for an operating load of 24,000 pounds at 500° F. The materials used consisted of 1 ¾ x 10 x 128 ¼ thick A-36 Carbon steel, with three 2½ studs and nuts.

40" Diameter, Alloy Yoke Clamp
40″ Diameter, Alloy Yoke Clamp

PT&P specially designed and manufactured a heavy duty, 40-inch diameter, alloy yoke clamp (cut from a 6″ thick plate) for a Power Plant in Mississippi. The clamp was designed for a 70,000 lb load and is to support a 40″ diameter, high pressure main steam line. The u-bolt was made of a 3″ diameter bar. In order to prove the design of this clamp, Finite Element Analysis was used to simulate the loads and stresses that it may experience in the field. The model shows the stresses at every point by a color coding system.

Arrestor Type Hold Down

March 9, 1994
Arrestor Type Hold Down
Arrestor Type Hold Down

The above photo shows an arrestor type hold down. This type of restraint is used when there is very low thermal movement. Its radius is lined with a belting material designed to absorb shock from movement. It is widely used on compressor lines or similar applications. The restraint type hold down’s clamp radius and base is lined with PT&P’s PTFE slide plate which allows for axial movement while restraining lateral movement and used on compressor lines where temperatures are high and thermal movement is great. This anchor type hold down is utilized on pipelines and require little or no insulation. It is fabricated from carbon steel and can be used in temperatures up to 750oF.
