Sanitary Tube
OverviewCleanliness, sterilization and safety are mission-critical factors in order to maintain and deliver
superior quality products to their consumers especially for the food or pharmaceutical industries.
As a result, the sanitary piping system requires very selective specifications of the stainless steel
tubes to be the major parts of the production processes, The tube’s inside wall must be extremely
smooth, crevice-free, and high pressure, low/high temperature and acid resistant, in order to avoid
all possible corrosions and ensure the better flow of fluid, easy to clean up and long hygienic
conditions.
Be mindful and using high qualities materials with the state of the art production technologies,
today we could offer a wide range of high purity sanitary tube under 3-A Sanitary Standard, which
is a specific standard genuinely designed for food, pharmaceutical, cosmetic, flavor, fragrance and
chemical industries.
In addition, as a leading manufacturer, we provide not only premium quality products but also
competitive prices and capable professionals to give our customers the confidence to know and
select product specification perfectly matched their investment and concerns.

Sanitary Tube
ApplicationAs sanitary tube is genuinely suitable for various industries, it is widely used as parts of production processes requiring hygienic conditions. Therefore, they are widely used in order to ensure the production process to be able to deliver good quality products. For instances, Milk and Wine producers, Milk can get rotten easily and if there are stains stuck inside, it can affect the product quality. For Wine, there might be fruit acids that cause corrosion to some metals. As mentioned, they are all factors for particular products would consider the tubes that are fit to their requirements. No matter food, beverage, medicine, high or low temperature requirements, or any aspects, sanitary tubes technically are widely used in order to secure the quality. Based on our customers, here they are some solutions that sanitary might be applied in order to maximize quality for each product types as follows. |
1. Pneumatic Test
Each tube, with internal surface clean and dry, shall be internally pressurized to 150 psi (1034 kPa) minimum with clean and dry compressed air while being submerged in clear water. The tube shall be well lighted, preferably by underwater illumination. Any evidence of air leakage of the pneumatic couplings shall be corrected prior to testing. Inspection shall be made of the entire external surface of tube after holding the pressure for not less than 5 seconds after the surface of the water has become calm. If the tube shows leakage during the air underwater test, it must be rejected. Any leaking areas may be cut out and the tube retested.
* This test is for demonstration on web page only! Please be informed that all testis are under ASTM Standard. For more information, please contact us.

2. Roughness Test
After the surface is finished by mechanical polishing, the roughness measurement (RA) must be applied in longitudinal direction. Moreover, this measurement must be a matter of agreement with our customers.
We test a sample from the first tube from a batch and compare it to the specimen.

We test a sample from the first tube from a batch and compare it to the specimen.
- If the sample passes, continue polishing. Thereafter, all of them must be measured in roughness test.
- If the sample doesn’t pass, readjust the machines, re-polish the sample and re-test.
3. Hardness Test
Hardness test is an method to evaluate tensile strength, yield strength and elongation of a tube whether it can endure high pressure.
* This test is for demonstration on web page only! Please be informed that all testis are under ASTM Standard. For more information, please contact us.
4. Flaring Test
A tube sample, one sample per 6 meters of 10 lengths, must stand and be flared with a tool to form a 60 degree of wide-open mouth of flare without any cracks or imperfections.
* This test is for demonstration on web page only! Please be informed that all testis are under ASTM Standard. For more information, please contact us.
5. Flattening Test
Tube sample shall be split longitudinally 90 degree on each side of the weld and the sample opened and flattened with the weld at the point of maximum bend without cracking or lack of penetration or overlaps resulting from flash removal in the weld.
