Reliable Pipes and Tubes Ltd. holds stocks of pressure vessel plate manufactured and certified to BS 1501 225 490B LT50 despite the fact that BS 1501 was officially withdrawn as long ago as 15th February 1993. It is still a specification that is asked for by our customers which is why it is important for us to be able to offer the product with manufacturers' certification from our stock.
