Stock Services 2016 – The Year Ahead.

Stock Services 2016

After a very difficult year in 2015, Stock Services will continue to hold stock of fittings and flanges in our UK warehouse facility.

We have realigned all our prices to the current market levels (weeps) and are fully replenishing our Seamless Butt Weld Fittings.


What’s the plan for 2016…the ‘short term?’

We realised last year that we need to be able to offer a bigger range of products to be successful.

This year we are going to focus on increasing our range of products that we can supply to include the below:

  • Seamless and Welded pipes and tubes
  • Fittings in Welded and Seamless construction
  • Flanges in pressure ratings of 150#, 300# and 600#

All of these products, and full stock availability, will be shown on our online catalogue very soon. In the meantime please send us your enquiries as normal.


More airfreight jobs.

We are still supplying goods by airfreight, and took many orders in the run up to Christmas from new and old customers.

We are being most successful supplying large fittings both in seamless and welded construction and large uncommonly held flanges.

Don’t miss out on a potential order due to difficulty sourcing flanges and fittings, we can often have these items manufactured and delivered in 15-35 days. Uncommon grades, sizes and schedules are no problem for us 🙂

Medium term – The website/shop.

We are going to be redeveloping our website significantly in the coming 3-4 months and making some big improvements for you the customer.

The new website will allow users:

  • To log on quickly and easily
  • Request quotations for a larger range of products than currently offered
  • Save or revalidate your historic quotations
  • View your order history online
  • View/download your test certificates and invoices
  • You will even be able to place your orders online if you like

We will send out more updates about the website, before it goes live, and hope that some of you can help us with a bit of ‘constructive feedback’ on the test site, before the live version comes out later in the year.


2016 – A year of opportunity perhaps?

If 2015 was a difficult year for anyone who had an involvement within the petrochemical industry, it is highly likely that 2016 will be even more challenging. With that in mind we would like to thank all our customers for the support they have given us last year, and wish you all a successful year in 2016.

We plan to continue to make it easy for you to do business with us, so keep us in mind with your enquiries for stock and difficult to source items.

Good luck…and thanks for reading.

Flanges – Tips for an easy life.

The Golden Rules of Stainless Steel Flange supply

Flanges are amongst the most critical components in a pipeline. They are used as connections for pumps, valves, strainers etc. and for pipework which has to be regularly dis-assembled and re-assembled.

It is critical that the correct flanges are supplied that can cope with the pressure of the system and are compatible with all the components which are connected in the pipeline. A flange is specified by the nominal pipe size and the pressure rating. However, there are distinctly different types of flanges depending on the plant design. In the offshore, petro-chemical, power and nuclear power industries they are generally designed in the USA, UK or Germany. There are of course flanges required for the paper pulp, water, brewery industries etc. but the rules of suitability remain the same.

Those who are regularly involved in the buying and selling of flanges, will be all too aware of how easy it is to supply the wrong flange if the correct questions are not asked. In this short piece we outline the do’s to supply the correct flange which will avoid delay, frustration and most importantly costly mistakes!

Listed is a short tick list of the relevant questions for the correct identification of a flange

Golden rules for flange identification

  1. Stainless Steel Grade: 304L, 316L, 1.4306, 1.4404, 31803, 254SMO, UNS 31254 etc.
  2. Pipe Size: NB (Nominal Bore), NPS (Nominal Pipe Size), DN (Diameter Nominal)
  3. Dimensional specification: ASME B16.5, EN1092-1, BS4504, BS10, API605 etc.
  4. Pressure Ratings: 150#, PN16, Table E etc.
  5. Type of Face: RF (Raise Face), FF (Flat Face), RTJ (Ring Type Joint) etc.
  6. Quantity Required


  • There is no such thing as a ‘better grade’ of steel, and a higher price does not mean better quality or performance. Instead steel is manufactured to internationally recognised specifications to fulfil a particular application. Material grades may or may not be interchangeable, but it is essential that the grade of steel is fit for purpose. You must find out exactly what grade of material is acceptable before supplying or purchasing a stainless steel flange.
  • Flanges of different dimensional specifications and pressure ratings are not interchangeable.
