How Bonlok Non-Welding Pipe Connection Technology Works

HOW BONLOK WORKS

Swaging is the controlled uniform reduction of the fitting end over the tube whereby forces are applied equally 360 degrees around the fitting. The result of swaging creates a permanent connection between the fitting and tubing by plastically deforming together as an assembly.

Bonlok Non-Welding Pipe Connection Technology Best Use

SUITABLE FOR

  • Water mist fire suppression pipe systems
  • Hydraulic pipe systems
  • Fuel supply and transfer pipe systems
  • Bilge and ballast piping systems
  • Starting air systems
  • Vent and sounding pipes
  • Gas supply pipe systems

ABOUT PRODUCTS

BONLOK is a purely cold-work, non-welding pipe connection technology that is at least 10 times faster than welding.

It eliminates the need of X-Ray NDT and hot-work during pipe connection for a safer, faster and cleaner working environment.

About Bonlok Products

TECHNICAL SPECIFICATIONS

STANDARDS
Temperature range: –50 °C up to +600 °C
Working pressure: up to >1000 bar
Standards: Useable for seamless and welded pipes

MATERIALS

DIMENSIONING OF THE WALL THICKNESS
The dimensioning of the pipes is done to DIN 2413 or to ANSI B 31.3 for a given pressure for the particular application. For further specifications consult the pipe manufacturers.

STEP BY STEP

01

Driver moves Press Ring to closed position, compressing fitting body onto pipe wall.

02

High compressive load on pipe from sealing rings creates gas tights double seal.

03

Dynamic load between pipe and BONLOK fitting delivers enhanced joint integrity to resist in-service Flex, Vibration and Pull-out loads.

QUALITY AND RELIABILITY

The BONLOK 100% metal to metal joint is a direct replacement for welded joints, providing a superior alternative to most alternative pipe connection systems. The assembly process eliminates the human variation so often found in alternative systems, producing an identical and perfect result every time. With no re-work and guaranteed long term reliability, the BONLOK quality saves you money.

INSTALLATION TIME

Preparation for the perfect connection is a simple and fast process. Uncomplicated “Fit/No Fit” tools are supplied ensuring the right fitting for the pipe. Pressing each side of the BONLOK fitting takes as little as 15 seconds. Faster installation saves you time and money.

WEIGHT SAVING

Often saving weight requires a sophisticated solution with elevated costs. With BONLOK, specifying pipe to the pressure requirement of the system, rather than the thickness necessary for the welding process, gives the opportunity to reduce the total weight of steel required, cutting down the cost for the piping. Saving weight saves you money.

FIRE AND EXPLOSTION RISK

In many environments fire or explosion is a real concern. The BONLOK connection does not generate heat or sparks and so the high pressure swage technology is not classified as how works.

COORDINATION SPACE

Comparing the BONLOK system with a flanged joint system. There is considerable scope for reduced spacing between ceilings and deck. Reducing overhead coordination space has saved cruise ship designers tons of weight, impacting displacement and vessel stability, ultimately saving the operators money.

FLEXIBILITY IN PRODUCTION SCHEDULING

The BONLOK system allows you to assemble and install a piping system without finally pressing the fittings. The visual indication that a fitting is not pressed is an excellent feature for production and QC purposes which also allows for greater flexibility in production scheduling. Having flexibility in your production schedule, considerably saves time and money.

BONLOK TESTING

Bonlok Testing

BONLOK has the broadest range of fittings, across a wider size range to be sure we can provide you with a complete solution. BONLOK fittings are used in critical systems and therefore testing the technology comprehensively to its limits has been an essential element part of the development of the technology, the products and the company.

We have spent over US$1,000,000 on outsourced testing to simulate the most demanding and extraordinary conditions that BONLOK fittings might be subjected to in service.

BONLOK SWISS DESIGN

BONLOK fitting technology is the third generation of the Haener Axial Press Swage Ring (HAPS) Joint, originally developed by Gottfried Haener who is the Senior Technical Advisor to the BONLOK

CERTIFICATION AND APPROVALS

The extensive performance testing programme has resulted in BONLOK successfully securing the Type Approvals and product performance Certification necessary for use in many industries with pressures in excess of 400 bar. The certification process is ongoing as we respond to customer requests to enable the selection of BONLOK fittings for an ever wider range of applications
