1.1IntroIntro.ky IntroDIN Fittings and TubesIntroductionDear Reader,You are sitting with our brand-new catalogue for DIN Fittings, but why,a new catalogue?After years of intensive work with the portfolio we have achieved aunique surface appearance across the different DIN Fittings of whichwe are very proud. We have uniformed our marking, to support ourhigh-quality Fittings and the result is fantastic. We call this range for“DIN Standard, new surface”, to highlight it, and give it a specialspace in the new catalogue, because it truly is unique. With focuson simplicity we have reduced the surface appearances to two onmachined and one on tubular Fittings and we have concentratedon “Hygienic Fittings” with an exception of DIN 11864. We haveinvested heavily in availability of “DIN Standard, new surface” portfolioand supported by the new automatic warehouse in Kolding and ouronline ordering tool “Anytime”, this will provide a superior customerexperience. Moreover, we have divided the catalogue into the differentDIN standards, to show the differences and make it easy to choosethe right product.The old portfolio is, where possible and convenient, upgraded to our“DIN Standard, new surface”, the rest we have kept “as is”. In the pricefiles we have made the following split:“DINStandard, new surface”.“DIN Standard, old surface”“Fit to DIN Tubes”The complete DIN Fittings range we supply fits with the tubedimensions of EN 10357-A and DIN 11866- Reihe A (except from DIN11851 W, which is according to the standard). The products in thechapter “Fit to DIN Tubes”, have deviations from the DIN standards,but will still fit to EN 10357-A tubes.Thank You for reading this and we hope You enjoy!Product presentationAlfa Laval’s range of DIN Tubes & Fittings are used in food, dairy,beverage, personal care, biotechnology and pharmaceutical processapplications. Smooth, crevice-free interiors and secure, self-aligningjoints are characteristic for Alfa Laval fittings. Each offers superiorcorrosion-resistance and unmatched service life. Alfa Laval fittingsare designed and manufactured to ensure dimensional accuracy andstructural integrity, making them easy to install. Tubing is manufacturedto Alfa Laval’s stringent specifications, making it a perfect matchfor the fittings. All products are labelled with a bar code, productinformation and manufacturing date. This provides the optimumidentification and ensures that the product arrives to the job site in aclean orbital weld condition. On the product we have laser marked allthe needed information such as heat number, dimension, surface,material and country of origin.1.1.3

1.3Marking and SurfaceMarking and SurfaceSurface descriptionsWe have chosen to provide a limited choice, most used, of all the surface possibilities. We have given them an Alfa Laval name. The names anddescriptions are like in the below table.Our surface philosophy has been to create a uniform surface finish which meets the standard or better and at the same time fits with the outersurface appearance of the DIN tubes across all DIN Fittings. The range “DIN Standard, new surface” will provide this benefit and will be visible inplants using Alfa Laval DIN Fittings only.The new uniform appearance of all Alfa Laval DIN Fittings is also the reason for new surface descriptions. This is a unique product and therefore itdeserves a unique surface description.The surface on tubular fittings exceeds the requirement in DIN 11852. We are meeting the requirements to surface roughness in EHEDG and 3A. Ourcustomers are therefore buying a product with a better surface roughness than most of the market supplies.Machined FittingsAL descriptionSurface texture Ra µm (µ-inch)WettedNot wettedStandardDINHSF0(Hygienic)DIN UltraPureH3 0.8 (32) 1.6 (64) 0.8 (32) 1.0 (40)Tubular FittingsAL descritpionStandardSurface structureWettedID/ODSurface1ForHSF2DIN (Hygienic)HSF31DIN face texture Ra µm (µ-inch)Not wettedweld beadSurfaceweld bead 0.8 (32) 0.8 (32) 1.6 (64) 1.6 (64) 0.8 (32) 0.8 (32) 0.8 (32) 0.8 (32)sizes larger than DN100, the "Not wetted" surface Ra can be upto 1.0 µm.Our products are mechanical polished.

Basics1.4Technical informationTest procedureOur manufacturing facilities operate under an approved ISO 9001 quality standard. Wall thickness integrity is maintained using fabrication grademinimum wall tubing for all cold-formed tubular products.Our fittings are put through visual inspection and ovality and squareness tolerances are inspected with calibrated equipment. Surface finish is inspectedwith calibrated profilometer to ensure the Roughness average (Ra) maximum is not exceeded.CertificatesAll product wetted stainless-steel products are delivered with a 3.1 certificate in accordance to EN 10204. You can find the certificates ckingWe protect our products by packing them into high quality cardboard boxes. This ensure they keep the high quality during storing and transportation.Packing sizes as below:DN10-DN80 10 pcs per cardboard boxDN100 5 pcs per cardboard box DN100 1 pcs per cardboard boxRubberRubber MaterialsIn order to obtain the longest possible lifetime for rubber seals it is essential to choose the right quality for the actual duty. Consequently when choosingrubber quality, the characteristics of the different rubber types should be considered. All product wetted rubber material are in conformity of FDA.EPDM Rubber (Ethylene Propylene)EPDM rubber is widely used within the food industry as it is resistant to most products used in this sector. Another advantage is that it may be used toa recommend max. temperatures of 140 C (244 F). However, there is one essential limitation, EPDM is not resistant to organic and non-organic oilsand fats. The resistance to ozone is excellent.Actylonitrile Butadiene Rubber, NBRNBR is the rubber type most frequently used for technical purposes. It is quite resistant to most hydrocarbons, e.g oil, grease and fat. It is sufficientlyresistant to diluted lye and nitric acid and may be used to a recommend max. 95 C (203 F). As NBR is attacked by ozone it may not be exposed toultraviolet rays and should thus consequently be stored so that this is avoided.Silicone Rubber, QThe most significant quality of silicone rubber is that it can be applied from temperatures below -50 C (-58 F) to approx. 180 C (356 F) and stillkeep its elasticity. The chemical resistance is satisfactory to most products. However, undiluted lye and acids as well as hot water and steam maydestroy silicone rubber. The resistance to ozone is good.Fluorine Rubber, FPMFPM is often used when other rubber types are unsuited, especially at high temperatures up to approx. 180 C (356 F). The chemical resistance is goodto most products, however hot water, steam, lye, acid and alcohol should be avoided. The resistance to ozone is good.Hydrogenated actylonitrileButadiene Rubber, HNBRMechanically strong and normally resistant to ozone and strong oxidizers, animal and vegetable fats, nonpolar solvents, oils and lubricants, water andaqueous solutions. The recommend max. temperature is 130 C (266 F).Perfluoroalkoxy polymer, PFAPFA is very similar to PTFE, but opposite to those PFA is thermo plastic and has minimal porosity. PFA has a very high mechanical strength whichmakes it a perfect choice when dealing with abbrasive products. The PFA seal offers longer service intervals. The recommend max. temperaturefor the PFA seal is 90 C (194 F).1.4.22
