Tubes: details make the difference

Did you know that 90% of product contact surfaces in a typical pharmaceutical system come from tubes? Let’s look into the details that make tubes different.

All Tri-Clover UltraPure tubes are subject to rigorous quality control. Alfa Laval performs all incoming and outgoing quality control and inspections and closely monitors every aspect of the manufacturing process – ­ from raw material sourcing to tolerance and surface finish inspection to packaging and labelling. Ovality and squareness tolerances and all surface finishes, for instance, are inspected with calibrated equipment. This helps ensure the highest quality possible.


Safe and easy installation

Tri-Clover UltraPure tubes originate from the same raw tube supplier to ensure that the materials in the weld ends match perfectly. Both chemical composition and passivity state are guaranteed to ensure maximum compatibility and integrity throughout the range. This simplifies welding and assures continuous high quality welds without cracks, voids, porosity, or joint misalignment that can promote contamination of the end product.

Completely documented

All equipment and components in the Alfa Laval BioPharm portfolio are supplied with Alfa Laval Q-doc, a comprehensive documentation package that provides full transparency of the entire supply chain, from raw material to final equipment delivery. This smoothes purchasing and installation procedures as well as facilitates qualification, validation and change control procedures. Based on GDP (Good Documentation Practice), Alfa Laval Q-doc covers every aspect of BioPharm equipment supply and provides customers with  transparent and well-documented quality assurance of the sourced equipment.

The Q-doc package for Tri-Clover UltraPure tubes comprises quality and manufacturing procedures, material certificates and full traceability. This attention to detail maximizes uptime and minimizes risk.

Readily available

All Alfa Laval UltraPure tubes are individually capped and packed together with the mill test report in sterile, transparent bags labelled with bar code, product information and manufacturing date. In addition, all products have heat numbers, job numbers, the Alfa Laval brandmark permanently etched onto the external surface.

Alfa Laval offers competitive pricing and fast, efficient delivery without compromising product quality. To meet customer requirements, Alfa Laval factories and distribution centres can supply:

1. Single fittings (one to nine pieces) from the entire product range.

2. Boxes of 10 for most standard products.

3. Full pallet for the most popular products.

4. Entire container of products directly from the factory.


How it works

All Tri-Clover UltraPure tubes are manufactured to stringent Alfa Laval specifications in Alfa Laval's own factories. This ensures complete control over quality standards, and all such tubes bear the Alfa Laval brand mark as proof of being the genuine article. They are also labelled with a bar code, product information and manufacturing date. This provides accurate identification and full traceability, and ensures the product arrives on site with a clean orbital weld.


Transporting process fluids by pipe often requires alterations in the line of flow. Key criteria for problem-free operation include strength and durability.

To provide maximum structural integrity and trouble-free flow, Alfa Laval manufacturing processes feature unusually tight tolerances along with uniform wall thicknesses, with all the angles exact and all tube, bend and tee connections uniform.

Unions, clamp fittings and flanges

All Alfa Laval flanges and clamp fittings are designed for easy, rapid maintenance. Flanges and clamps with finger nuts are especially suited for processes in which the load on seals is extra high, where the easy checking and replacement of seals is important and where effective cleaning is required.

To supply the type of seal most appropriate for each particular process, Alfa Laval provides a wide range of options. These include seals made of nitrile rubber (NBR), fluorine rubber (FBR) and ethylene propylene (EPDM).

Unions are available to provide compliance with standards that include ISO, DIN and ASME.


Reducers are used to connect tubes or pipes with different sizes or shapes. The stresses involved at these key points means reducers are often a prime location for leakages in a flow stream.
Alfa Laval reducers feature cylindrical welding ends and uniform wall thicknesses for all tube combinations, ensuring the right diameter and wall thickness for each specific flow stream.


In applications that involve fluid handling, different flow streams often have to be merged using tee pipes.

Alfa Laval manufactures tees with uniform wall thickness, tight tolerances and a wide selction of different finishes, to ensure the greatest possible strength and long service livfe, as well as problem-free welding and assembly. Alfa Laval tees are all made of AISI 304 or AISI 316L stainless steel and are available in 1–4-inch diameters and from DN10 to DN150.

Wide range of surface finishes

Alfa Laval fittings are available with a wide range of surface finishes, electro and mechanical polish. Mechanical polishing uses a progressive series of abrasives – from coarse to fine grit – to produce a consistent internal finish that supports effective yet economical cleaning.


The Alfa Laval ranges of UltraPure tubes help ensure the best possible levels of hygiene within any installation. The tubes are specially manufactured to provide maximum hygiene integrity in ultra-clean processes. Each range is also designed and manufactured to ensure dimensional accuracy and structural integrity, making them easy to install. It also makes sure that Alfa Laval tubes provide users with superior corrosion-resistance and unmatched service life.
