Hygienic range tubes and fittings

The Hygienic product range offers a wide range of tubes and fittings with an internal surface finish from Ra< 1.6 µm. The Hygienic range has tubes and fittings according to EN10357 A (DIN 11850), ISO 2037 and BS 4825. Tri-Clover Tri-Clamp® and Tri-Weld® Fittings are part of Alfa Laval’s product line produced according to ASME BPE dimension standards. Tubing is manufactured to Alfa Laval’s stringent specifications, making it a perfect match for the Weld Fittings. Choose from a complete range of tube sizes and connection options. The internal surface finish is Ra< 0.8 µm. All product wetted stainless steel items in the Hygienic range are delivered with 3.1. certificate in accordance with EN 10204

UltraPure range tubes and fittings

Alfa Laval is proud to present the line of Fittings designed for use in the Pharmaceutical and Bio-Technologies Industries. This line consists of Tri-Clover® parts with either Tri-Weld® ends suitable for use with Orbital Welding Equipment or self aligning Tri-Clamp® end connections. Alfa Laval offers a full line of UltraPure Fittings that are manufactured in compliance with the current ASME BPE Standard. All BPE items are individually capped and bagged. All products are labelled with a bar code, product information and manufacturing date. This provides the optimum identification and ensures that the product arrives to the job site in a clean orbital weld condition. The UltraPure product range offers an internal surface finish from Ra< 0.8 µm, either electro polished or mechanically polished. All product wetted stainless steel items in the UltraPure range are delivered with MTR (Mill Test Report) or with 3.1. certificate in accordance with EN 10204. The UltraPure range is manufactured under extra strict and thorough quality control methods. Wall thickness integrity is maintained by fabrication grade minimum wall tubing for all cold-formed tubular products. After cold forming, our tube product is resized to ensure that the ovality falls within the prescribed tolerances. End facing is provided with a machined square-cut method. This allows for the most accurate and consistent orbital weld result. All fittings are put through 100% visual inspection and ovality and squareness tolerances are inspected with calibrated equipment. Surface finish is inspected with a calibrated profilometer to ensure the Roughness average (Ra) maximum is not exceeded.

Technical Data

Alfa Laval offers a range of Mechanical Polish as well as Electropolish finishes. Mechanical polishing is achieved by using a progressive series of abrasives, from low to high grit. This allows a consistent internal finish and both optimal and economical cleaning. Electropolishing is a further process that promotes a chromium-enriched surface layer that maximizes corrosion resistance as well as minimizing bacterial build up on surface cavities. Metallurgy - Incoming raw material goes through a stringent inspection process to ensure its chemistry will be ideal for both weldability and electropolishing Quality Control Methods - Our manufacturing facilities operate under an approved ISO 9001 quality standard. Wall thickness integrity is maintained with fabrication grade minimum wall tubing for all cold-formed tubular products. Our BPE fittings are designed for use with all current orbital welding equipment. After cold forming, our tube product is resized to ensure that the ovality falls within the prescribed BPE tolerances. End facing is provided with a machined square-cut method.
