BS CODES FOR WATERWORKS PLANT

[chinwar]

DEAR ALL:
I NEED TO PREPARE PIPING SPEC FOR A WATERWORKS PLANT. BUT MY CLIENT ASK US TO USE BRITISH STANDARDS WITH WHICH I AM NOT FAMILIAR AT ALL. MAY ANYONE TELL ME SOME CODES NUMBERS FOR FOLLOWING ITEMS:
1. MATERIAL CODES FOR C.S., S.S., PVC, UPVCS AND ABS
2. PIPES, FITTINGS, FLANGES, NUTS, BOLTS, GASKET AND VALVES FABRICATION AND TESTING STANDARDS
3. WELDING AND PIPING DESIGN STANDARDS
THANKS

Chinwar,
The major manufacturer of CS pipe & fittings in the UK is Saint Gobain Pipelines ( was known as Stanton in bye gone days )
The web site is :

http://www.saint-gobain-pipelines.co.uk

They will have the BS or EN ( european) standards available, if not e-mail them.

Hope this is of use.

I suggest you contact British Standards via their website. You may also want to consider the WRC codes.

As an alternative you might suggest to your client that you use Australian Standards. These are close to British Standards. The standards are also less expensive than British Standards and I can help you out with a list.

Thanks all
in fact, my poject consultant comes from UK so there is no choice to deviate from their tender specification which requires BS shall be adopted. while i found a lot of mistakes in their specification, it is hard to prepare our piping specification for this project. for example, they ask us to use pn16 flanges because surge pressure can reach 10 bar. but they also require raised face flanges shall be used for the project.ok, after checking bs4505 pn16 flanges, i found the largest size for pn16 sorf flanges is up to dn1200. but my pipe size is up to dn2200. what shall i do? i need to prepare some special drawings for flanges but i need to follow awwa standrads. and my process also give me troubles to use dn1550 and dn1500 pipe.
then they mention the pipe size and thickness in the tender specification which absolutely match ansi standards while they ask bs3600 or 3601 shall be used for cs pipe. what a hell if u check bs3600 for size dn2200, which shows the pipe od is 2235. but my tender asks od 2220 pipe shall be used. ok, again, neck sizes for wn flanges shown in bs4504 are different from bs3600 pipes! you can see what a mass i met.
i know there are two series of pipe size.
it is my first time to touch bs, so i need some organization info for bs.
so where can in find it

Suggest you may have to revert to BS 5500 the Pressure vessel code if it is mandatory that you use BS. Sharing knowledge is a way to immortality

There is no difference ISO 2531 and BS EN 545:2002 for ductile iron pipe. ISO standards are used interchangeably with BS standards in UK.
