Description
Sanitary Spool Tube PuroFlow
Sanitary spool tube is a complete pipeline assembly prefabricated and welded in advance, processed and formed with ss sanitary tubing as the base material.
As ASTM A270 stainless steel sanitary tubing manufacturers, we can customize complete spool assemblies according to customer drawings and on-site working conditions, eliminating on-site cutting, welding, and polishing processes and greatly shortening project installation time.
Sanitary Spool Tube Specifications
The table below provides reference for commonly used custom sanitary spool tube dimensions and supports combinations of various connection end types.
| Nominal Size | Tube Base Material | Available End Types | Inner Wall Ra |
|---|---|---|---|
| 2″ | 304 / 316L stainless steel sanitary pipe | Tri clamp / Butt weld / Thread | ≤0.8 μm |
| 4″ | 304 / 316L stainless steel sanitary pipe | Tri clamp / Butt weld / Thread | ≤0.8 μm |
| Custom | 304 / 316L | Combined per drawing | 0.4~0.8 μm |
Note: sanitary spool tube with tri clamp ends is the most commonly selected style by customers; it facilitates quick connection to clamp fittings and is suitable for clean pipelines.
Product Standards and Processing Technology
The base material of prefabricated spool pieces follows the ASTM A270 sanitary tubing standard and belongs to welded sanitary spool assembly. Orbital automatic welding is used; the welds are polished inside and outside, with no sanitary dead corners, meeting 3A, FDA, and CIP online cleaning requirements.
We can provide material certificates, welding inspection reports, and polishing inspection reports.
Core Advantages of Sanitary Spool Tube
Factory prefabrication: prefabricated sanitary spool tubing; on site only assembly and connection are required, reducing the risk of on-site welding contamination.
Flexible customization: length, pipe diameter, end type, and fitting combinations can all be designed on demand.
Clean and stable: welds are polished in a controlled workshop, and quality consistency is better than on-site processing.
Suitable for multiple industries: can be matched with clamp, butt weld, and other connection structures.
Applications
Widely used in clean conveying pipelines for food and beverage, dairy, pharmaceutical, biological fermentation, and fine chemicals; suitable for engineering projects with tight schedules and high cleanliness requirements.
