Hygienics Introduction/Tube Range
Stainless Steel Hygienic is the name given to a range of tube and Fittings used in applications requiring a clean and sanitary Flow of liquids and where it is essential to avoid contamination of the products being carried.

These applications cover the food processing, beverage, biotech and pharmaceutical industries including breweries and dairies.
The applications are low pressure with a maximum of 150lbs.
The products are available in grades 304 and-316L.
The size range is from 1/2 inch to 6 inch O/D.
eliminating the risk of contamination or bug traps as well as facilitate easy cleaning.
The tube and Fittings are offered with a choice of
external finishes:
• Descaled
• Bright Annealed
• Dull Polished
• Semi-Bright or Bright Polished.
Manufacturing standards
Hygienic tubes are manufactured to ASTM A270, DIN 11850, ISO 2037 and BS 4825 Part 1.
Hygienic Fittings are manufactured to BS 4825 Parts 2 to 5,3A,DIN11851,DIN11852,DIN11853 and SMS 1145,SMS11183,
Markings on tube and fittings
Tube and Fittings with a bright annealed or polished finish will be unmarked.
Range/Sizes - Tube
Sizes to ASTM A270
O/D Wall Weight:1.2-2.8MM


3A
The modern concept of the 3A sanitary standard was established in 1944 when the Surgeon General of the United States Public Health Service (FDA) and the Chairman of the Sanitary Standards Subcommittee of the Dairy Industry's five national trade associations committed to full cooperation with the 3A program.
The purpose of the 3A Sanitary Standard is to formulate design criteria to cover a single piece of equipment relating to accepted practices by users, equipment
manufacturers and the International Association of Milk, Food and Environmental Sanitarians.
Once the 3A Sanitary Standard becomes effective for a manufacturer's selected equipment, authorization to use the 3A Standard symbol comes from eight board
members of the Dairy Industry Council, the Dairy and Food Industry Association and the International Association of Milk, Food and Environment Sanitarians.
The use of the symbol assures processors that the equipment meets sanitary standards, provides accepted sanitary designs and establishes uniform guideline by
Sanitarians.

DIN
DIN,the German Institute for Standardization,is a registered association,founded in 1917.Its head office is in Berlin. Since 1975 it have been recognized by the German Government as the national standards body and represents German interests at International and European level.DIN11851-Fittings for food,chemical and pharmaceutical industry;Stainless steel screwed pipe connections;Design for rolling in and welding-on.DIN 11852-Valves for food and chemical industries;stainless steel fittings;Tee,bends,reducers for welding-on. DIN32676-Clamp Fittings for the clamp and ferrules.DIN11851/2 and DIN32676 standards are used on the majority of the German hygienic equipment and are gaining widespread acceptance.

BS
BS4825-Stainless Steel tubes and fittings for the food industry and other hygienic applications.BS is widely used throughout the UK hygienic industries. It can be used on permanently installed pipelines but it is also designed for use where system are frequetnlydismantled.RJT-confirming to BS4825 part 5 and should be used in application where manula cleaning is employed.Particularly suited where liens are frequently dismantled due to thier robust construction and ease of alignment.

DIN EN ISO 1127
The ISO pipes are described in terms of dimensions in the standard ''DIN EN ISO 1127 stainless steel pipes'' (issued by BeuthVerlag GmbH, D-10722 Berlin) http://www.beuth.de. This standard derives from the standards DIN 2462 (dimensions of seamless pipes) and DIN 2463 (dimensions of welded pipes).

The dimensions, limit dimensions and lengths are defined herein. Contrary to the previous DIN 2462 and 2463, the definitions for seamless and welded pipes are integrated into one standard now, thus omitting the differences between both standards.

ISO pipes are manufactured from hot rolled sheet metal. The surface quality related to the parent material, which is described as slight ''orangepeelskin'',cannot be improved by polishing, contrary to the pipe standard DIN 11850 and others (cold rolled strip parent material).
Further determinations regarding the surface quality (roughness etc.) and ferrite content are not taken into consideration for ISO pipes.


SMS Union
SMS or Swedish Dairy Standard Unions are a 4 piece stainless steel union comprising of a male, nut, liner and seal. The male or thread, meets up with the flat faced liner and a seal sits into the male part to form a seal. A slotted nut completes the union and C-Spanner is used to open/close the nut. It use a lot for the dairy industry.
DS Union
Danish Standards Foundation, DS, was originally founded in 1926. DS is a member of the ISO, the International Electrotechnical Committee (IEC), the European Committee for Standardization (CEN), the European Committee for Electrotechnical Standardization (CENELEC) and the European Telecommunication Standards Institute (ETSI). The DS use in Europe Denmark,africa and South American countries mainly.
