William Johnston and Company Limited join forces with The Academy of Joint Integrity™.


William Johnston & Company Limited has been supplying gasket based sealing solutions for pipeline applications throughout the UK and on projects across the world for nearly 70 years. The combination of this experience and the global expertise of the Flexitallic group, leader in the manufacture and supply of static sealing solutions, combined with the technical excellence of The Academy of Joint Integrity provides  owners, operators and contractors involved in the design, creation, installation and maintenance  of pipeline networks, whether as part of a nationwide utility or within  plants  such as refineries  or distilleries,  with  access  to  bespoke  training at the highest level recognised in industry.

Are your gaskets compliant?

Are your gaskets fire safe?

Are your maintenance team or contractors certified in Flange Assembly?

Do you have a Flange Assembly Bolting Procedure compliant with Industry Best practice?

A bolted flanged connection is a complex assembly with many variables involving:-

• Selection of a gasket material  to the correct specification;
• Suitability of the flange material and its condition;
• Correct  style of flange to suit the application and the pipeline network;
• Bolt/stud length, hardness, thread size, finish, corrosion resistance etc.;
• The knowledge and  skill of the assembly personnel;
• Diligent knowledge and understanding of the relevant HSE regulations e.g.  COMAH  ;

Failure to appreciate and apply all of these criteria may lead to:

• Safety issues and possible injury in the event of an accident;
• Spillage and loss of product;
• Expensive downtime for the entire plant due to failure of a single flange;
• Costly repair work;
• Environmental damage and conviction and fines;
• Damage to a business’s reputation;
• Fines for the business and imprisonment for  its owners and operators;

Training is not expensive – all of the above issues are very costly
