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 four 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.

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.

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 intact.
• Bolted pipe shoes — bolts are intact, 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.

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.

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.
