Description
As a leading Chinese stainless steel pipe & tube supplier, CIVMATS produce high precision stainless steel capillary tubes with a tight tolerance of ±0.02mm under ISO 9001:2015. Our SS capillary tubes can be classified into four categories, AP tube, MP tube, BA tube and (Cleanroom) EP tube, among which BA tube and EP tube are the most popular and gain high recognition from different industrial applications, both home and abroad, due to high precision and greater corrosion resistance. For your reference, we can manufacture SUS 316L capillary tube containing 12 Nickel with enhanced corrosion resistance, particularly suitable for special applications such as high toxic gas. In most cases, TP 316L containing 10 Nickel will be sufficient for general corrosive services. The main ASTM standards we produce are ASTM A269, A270, A312, A554 and A249 for your divergent demands. At CIVMATS, the supply of our stainless steel capillary tubes comes in multiple dimensions and various grades. The main grades are 316(L), 304(L), 321(H), 309S and 310S. If you want non-standard size or grades not listed in our datasheet, we can customize for you upon our confirmation. For standard size of common grades, we have ex-stock for fast delivery. We can also provide small pieces of free samples upon your request for you to check quality. If you are interested in our stainless steel capillary tube, just call us or drop us an email, our sales will come to you shortly.

Package
Plastic Bag
Wooden case
In Civmats, all of our stainless steel capillary tubes are packaged as per international standard to prevent any possible damage or loss. By default, we will use thick woven plastic bag to bundle the finished SS tubes together in batches. However, for some special tubes that are vulnerable to dirt, scratches, stress or rough handling, we will suggest wooden case for protection. Kindly note, wooden case can incur extra cost, not only its own cost, but also the increased freight cost, which is especially true for air transportation. For enhanced customer experience, we also provide dedicated package as per your special requirements.
Logistics
By Sea
By Air
By default, we will quote based on sea transportation, such as FOB, CFR, CIF and the like for most enquiries or orders. Quotation based on air transportation is also optional upon your request for urgent demands.
FAQ
How many delivery states do you have for SS capillary tubes?
We have 4 delivery states for your choice: Annealed and pickled (AP), Mechanically Polished (MP), Bright Annealed (BA) and Electro-polished (EP).
What's your standard package for EP tubes?
For our EP grade stainless steel tubes, both ends of the finished tubes are protected with PA film and rubber tube caps. Anti-static bags are also used to further protect these tubes. At last, they will be placed into the wooden case.
Where's your main market?
Europe, Mid-east, South America, South-east Asia, and so on.
Can you provide samples for quality check?
Yes, samples of the pre-stock (very popular sizes and grade) tubes are available at small pieces at no cost; only the freight will be borne by you.
What's the popular capillary tubes?
BA grade and EP grade 316L capillary tubes are the most popular tubes at home and abroad. The most applied standard is ASTM A269 for your reference.
What length is your standard length? Can I have the tubes/pipes cut into the length I want?
Our standard length is 3meter, 4meter, 5meter, 6meter. We can also precut the tubes to the length that you want by laser cutting.
