What is BS 4825-1 - Stainless steel tubes and fittings about?
BS 4825-1 is a series of European standards on stainless steel tubes and fittings that discusses the best procedures and specifications required for manufacturing high-quality stainless steel tubes and fittings.
BS 4825-1 specifies requirements for stainless steel tubes in straight lengths for the food industry and other industries where hygienic requirements are necessary. BS 4825-1 covers seamless and longitudinally welded austenitic stainless steel tubes from 12.7 mm to 406.4 mm outside diameter, and specifies dimensions, tolerances, surface finish, and materials. BS 4825-1 does not cover ERW tubes.
NOTE: The suitability of a tube for a hygienic application is determined mainly by its material, finish, and the condition of the longitudinal weld.
Who is BS 4825-1 - Stainless steel tubes and fittings for?
BS 4825-1 on stainless steel tubes and fittings is relevant to:
- Manufacturer of stainless steel tubes and fittings
- Food industry
Why should you use BS 4825-1 - Stainless steel tubes and fittings?
Stainless steel pipe is primarily used in piping systems for the transport of fluids or gases. We manufacture steel pipe from a steel alloy containing nickel as well as chromium, which give stainless steel its corrosion-resistant properties. BS 4825-1 provides guidance on materials and manufacture, dimensions, tolerances, surface finish, manufacturer’s certificate.
As a user of BS 4825-1, you can be ensured of requirements for stainless steel tubes. With obedience and compliance to BS 4825-1, you can efficiently manufacture high-quality stainless steel tubes and fittings for the food industry and other hygienic applications. BS 4825-1 helps you to build consumer trust and confidence in the product. With BS 4825-1 you can be ensured that the products consistently meet and exceed quality assurance targets.
BS 4825-1 exemplifies the required dimensions and tolerances that help you achieve precision in terms of product functionality. BS 4825-1 provides you with comprehensive information useful throughout the process of production.
What’s changed since the last update?
BS 4825-1:1991+A2:2009 supersedes BS 4825-1:1991, which is withdrawn. The essential differences between this part of BS 4825 and BS 4825-1:1972 are as follows.
- A greater selection of materials is given
- Sizes up to and including 101.6 mm outside diameter are exact metric equivalents of imperial sizes of tube
- Alternative thicknesses of tubes of 1.6 mm and 1.2 mm have been included in the range from 25.4 mm to 50.8 mm outside diameter
- The tolerance band for exact lengths has been reduced
- Marking requirements are given in greater detail
