Sanitary Fittings –  SRS Sizing Charts Guide

First of all, these actual size drawings are provided to eliminate sizing errors when specifying sanitary fittings.

Also, the outside diameter is the same for 1/8″, 1/4″, 3/8″, 1/2″ and 3/4″ I.D., “mini” sizes (.0992 O.D.).

Furthermore, the same holds true for the 1″ and 1-1/2″ I.D. sizes(1.984″ O.D.). The 2″, 2-1/2″ and 3″ I.D. have specific O.D. diameters.

Also, for your convenience and ordering accuracy, all of these drawings may be used as sizing, I.D. and O.D. patterns.

For 4″ (not pictured): 3.75″ ID and 4.675″ OD

What are the Benefits of Electro polishing?

Electro polishing is the greatest form of passivation on stainless steel. Electro polishing removes surface metal by attacking high points on the surface.  this process makes the surface smoother while eliminating contaminants which results in a clean and sterile surface. Electro polishing is intended to reduce corrosion and extend the life of the product.

Food and beverage process equipment, also tubing and pipe, also medical equipment, and finally heat exchangers are just a few of the products that benefit from electro polishing.  The smoother surface finish derived from the electro polishing process and for that reason, will naturally reduce the collection of processed materials and contaminants on the product contact surfaces.

Also, The equipment will clean faster and for that reason be more effective when using a smaller volume of cleaning products.  Even more, It saves downtime expenses, also cleaning materials, and furthermore disposal of cleaning products if environmentally controlled near your facility.

After electro polishing, as a result the appearance of the surface finish is a bright and smooth polish with a great light reflection and above all showing clarity of the item.  Although the better physical appearance is pleasant to view, the most noteworthy benefit is the corrosion resistance.

Finally, Corrosion resistance is created by the passive layer created on the surface of the metal from the electro polishing process.  Certainly the more Free iron that is removed from the surface of the metal, the less corrosiveness it will probably be.
