KBS Long-Radius Roller-Bearing Tubing Benders
Get Precise and Reproducible Bends on Electro-Polished Stainless Steel Tubing. For Ultra-High Purity UHP Thin-Wall Electro-Polished Stainless Steel Tubing.
KBS Tubing Benders
Bend Steel, Stainless Steel, Aluminum, Brass, Soft and Some Hard Copper and Titanium
- Each tool bends up to 180 degrees and large radius bends are ideal for preventing smooth inside walls from cracking, flaking and generating particulate contamination.
- The open side slips over the tubing at any point. You get smooth long bends with no marking, scraping or flattening.
About Us
In the mid 1980's a well known semi-conductor fabrication facility in silicon valley was experiencing a 40% rejection rate of their chips due to particulate contamination in their process piping caused by bending tubing with standard radius tubing benders.
A contractor installing the process lines was asked if he could come up with a solution to the problem. After a couple of years of trial and error, the KBS Long-Radius Tubing Bender was invented and reduced the rejection rate from 40% to less than 10%. For a number of years now, KBS Long-Radius Tubing Benders have been required by all chip plants for contractors installing high-purity process piping.

BENDER MARKINGS AND INDICATORS
Springback
With some experience you will be able to predict the amount of springback to expect. Please allow for 1 to 3 degrees of compensation.
Verify the bend angle using a template, protractor or against a known angle to ensure the correct bend angle has been achieved.
Quality Control/Quality Assurance
The rugged heavy-duty, high-quality industrial grade construction of the KBS Long Radius Tubing Benders have been providing users with consistent, precise and repeatable bends for over 30 years.
