Are you even more desperate than that, and need them in a week? We can do that too. But I will have to introduce you to what we are now more politely* calling the “Distress Price” which is basically a 50% premium added to the standard price, for the privilege of jumping the queue. (When I ask “When do you NEED them by?”, “Yesterday!” is no longer a comedy answer!)

Do you want your heater to be British manufactured, to the highest possible standards, by highly trained people, paid proper wages to cover their British cost of living?

Then, with the whole of the WorldWideWeb to choose from, you have found the right place?

Typical Flange Dimensions.

As with pipes (hence the British Standard Pipe Legacy), it was necessary to standardise the dimensions of the various flange types depending upon requirements. Standardisation also facilitates easier communication between relevant parties (designer, manufacturer etc.), with a reduced likelihood of error. Typical Flange Dimensions

A piping designer in Canada may wish to instruct on site fitters in Kuwait to use a certain flange with specific dimensions. This process would be tedious considering the criteria that must be specified (internal diameter, outside diameter, thickness, hole diameter etc.). To circumvent this problem, the designer indicates the type of flange, its size, pressure class, schedule, and the standard to which it is to conform.

On this site, you will not only find an online catalogue of our core range of products. You’ll find tips, advice and guidance, as well as links to other resources to make your life easier. This includes our heating calculators.

On our blog, ElementsOfHeating there is a wealth of relevant and useful information. Such as an explanation of what a heating element actually is. Also we have a full description and explanation of the component parts of a screwed immersion heater and my best punt at explaining the joys of watt density, and it’s crucial importance when choosing the most appropriate immersion heater for water, oil, and breweries. Also available is an informational entry about the process we go through when designing immersion heaters generally.
