Frequently Asked Questions

Many factors other than just thickness determine the force required to bend steel.  In order to answer this question one must first determine the “yield strength” of the steel to be bent (the higher the yield strength the greater the force required to create permanent deformation to the steel).  One must next determine the size, more specifically the length of the bend line as that will determine how much area a given pressure must be applied across (the longer the bend line the greater the overall force is required to bend the material).  Finally one must determine the desired radius of the bend in order to select tooling options that also factor into the calculations required to determine the needed force to bend steel.  As a general rule, the minimum bend radius should not be less than 4 times the material thickness; however, this will go up with harder materials.  The larger the radius is the wider the block opening can be and the bigger the punch radius can be which reduces required force to make a bend.  All said, if your project requires plate bending our 750 Ton 5 Axis CNC press break may be able to get the job done, please feel free to send your inquiry through our CONNECT WITH DELTA link!

Spectacle Blinds are used when a valve cannot be installed to control the flow in pipe lines due to space restrictions, a spectacle blind is less in cost and smaller than valves.

Hold-down pipe clamps are the perfect solution for applications when you need to either anchor the pipe into position, or allow for axial movement of the pipe itself.

A hot shoe is a type of insulated pipe shoe/support that cradles the pipe, and is intended to withstand extremely high temperatures of over 200 degrees Fahrenheit.

Installing non-metallic wear pads is the simplest way to protect both your piping and clamps from metal-on-metal friction that could eventually lead to corrosion. You can also use a neoprene lining at the area where the clamp meets the pipe.

A split-t is a pipe shoe made from a cut w-beam. The flange becomes the base of the shoe and the web section is welded to the pipe.

Wear pads are used to protect process piping from wall-thinning due to contact with pipe racks and other metal structural components. To determine the size of a wear pad, one should consider:

• the wall thickness of the supported pipe.
  • thinner wall piping requires a larger contact surface.
• the capacity of the load being supported.
  • larger load capacity requires a larger contact surface.

A welding lug is a single plate intended to join other support components together with pins. The lug’s plate thickness depends on the load to which it is welded.

Pipe guides prevent bowing and buckling of pipe. Fabricated pipe guides ensure positive pipe alignment and are always recommended in applications involving pipe movement.

Always ensure that your pipe shoes lack severe corrosion or damage to the shoe plate components. Additionally, verify the following for these shoe types:

• Welded design pipe shoes—welds are in tact.
• Bolted pipe shoes—bolts are in tact, all components are tightened to the correct torque specifications.
• Insulated supports—bolts are intact and properly tightened, insulation is complete without being damaged or exposed to the environment.

An anchor system can be used to keep the pipe in position, with supportive structures incorporated into the design to maintain constant tension throughout the pipe’s operating cycle.

You should size your saddle pipeline shoe based on the diameter of the pipe and the thickness of the insulation.

Yes, if the clamps are lined with padding to dampen the vibration, such as neoprene or teflon.

Repads should be used to add strength in locations where pipes intersect.

Stops and anchors are types of pipe guides, with a main purpose of preventing bowing and buckling of piping. Stops restrict movement in two directions, whereas anchors restrict movement in all directions.

Pipe trunnions, also known as dummy legs, are used on sections of pipe as a support stand.  Trunnions are typically used when little to no pipe movement is foreseen.

Pipe guides are always recommended in applications involving pipe movement and can be used in all process piping systems.

An orifice plate is used to measure flow rate, then reduce the pressure and restrict the flow through the orifice in the middle of the blind.

Spectacle blinds (also referred to as a “spec blinds” or sometimes even “spectacle flanges”) are devices used to isolate a particular section of line or piece of equipment when the line or equipment needs to be safely inspected or removed.

Also known as paddle blinds, isolation blinds, are devices which temporarily halt the flow of fluid or gas while sections of process piping undergo maintenance.

Featuring a combination of spacers in the gapped flange, a purge blind is a device that’s used to create a tight seal and stop flange gasket surface damage while purging process piping systems.

Bleed rings (also known as drip rings) provide a safe and effective way to drain piping or bleeding valves.

Plate flanges are devices which allow pipe joints to be disconnected as needed, providing greater flexibility for piping system maintenance.

A spacer ring is a device that’s used between flanges to correct any potential gaps or misalignment.

Vent blinds are devices which allow one side of a blind to stop its flow, while the other side gives free access to purge and/or relieve the flow.
