Understanding ASTM A240 & ASTM A270
What It Is:
This product is defined by two essential standards that work together to guarantee a superior final product.
ASTM A240: This standard governs the raw material. It defines the precise chemical composition and mechanical properties of the stainless steel plate (e.g., 304L, 316L) used to form the tube.
ASTM A270: This standard governs the finished sanitary tube. It dictates the required manufacturing process, surface finish (Ra), cleanliness, and testing to ensure the product is hygienic and free of contaminants.
A Combined Quality Promise: We use fully certified A240 plate to create a sanitary tube that meets or exceeds all ASTM A270 requirements.
Why It Is Your Core Focus:
Our strict adherence to both standards is our commitment to delivering a product that is both materially sound and hygienically pure.
It guarantees the correct material chemistry for proven corrosion resistance and long-term durability in typical process environments.
It ensures an ultra-smooth internal surface that prevents microbial adhesion and allows for efficient, repeatable Clean-in-Place (CIP) and Sterilize-in-Place (SIP) cycles.
This dual certification provides you with fully traceable MTCs, simplifying the validation and approval process for regulated industries like pharma and food.
