Spider Guides for a Heat Recovery Steam Generation Plant Spider Guides
Components of these Cylinder Pipe Guides (a.k.a. Spider Guides) include carbon steel plates, stock clamps, angles, and hot-dipped galvanized pipes. The Guides range in pipe size from 6″ to 16″. The maximum design temperature for the Spider Guides is 750ºF.
They are designed to control lateral pipe movement and maintain the alignment of the piping through its axial and contraction cycles. A single piping run uses multiple Spider Guides to avoid a fulcrum or an imposed lateral deflection on critical components.

97" Diameter, 3-Piece Pipe Clamps for a Refinery in Ponca City
Piping Technology & Products, Inc. fabricated 3-piece pipe clamps used to support 97″ diameter stainless steel duct work. This duct work is being added to a refinery for an expansion project in Ponca City, Oklahoma. Each section of the clamp assembly is formed from a continuous plate and gussets are added at each of the bolt locations for increased strength and rigidity. Due to the ducts having a relatively thin wall, these clamps are designed wider than necessary in an effort to reduce localized stresses on the duct work. The lower section of each clamp is formed to create a 150° cradle. This acts as a cradle by supporting the duct without inducing extra pressure, which might cause the duct wall to buckle or bend.
The upper sections are formed from 1/2″ thick by 12″ wide bar stock, whereas the lower sections are formed from 1/2″ thick by 18″ wide. All three sections are rolled to an inner radius of 48 1/2″ and the welded gusset plates are all 1/2″ thick. The upper sections are formed at 105° each, and the upper load bolt is 2″ in diameter while the six clamping bolts are 1 1/2″ in diameter.
The maximum load to be carried by these pipe clamps is 16,888 lb. Each pipe clamp will be used in conjunction with a variable spring support to accommodate movements as high as 2 1/4″.

SWECO Fab, Inc. manufactured a pig launcher and receiver used to launch a pig throughout the piping system to clean the pipe line. Both the pig launcher and receiver have been hydro-tested to ensure quality and performance. Multiple coats of paint were also applied for environment protection.
