Description
As a leading Chinese stainless steel pipe & tubes supplier, CIVMATS produce and manufacture a wide range of stainless steel thick-walled pipe. Thick-walled stainless steel pipe, also named stainless steel hollow bar, are usually used for mechanical applications or manufacturing hollow components such as nozzles, reducers, couplings etc. These applications always require corrosion-resistant or high-temperature strength. Thick-walled stainless steel pipes can be furnished in different shapes such as round, square, rectangular etc. while hollow bars are produced in round shape. The most common standard applied for thick-walled stainless steel pipe or hollow bar is ASTM A511 / A511M-16 which covers requirements for chemical compositions, mechanical properties and diameters. CIVMATS CO., LIMITED produces thick-walled stainless steel pipe strictly according to the standard under ISO 9001 system. Each product delivered from CIVMATS is a brand warrantee.

Package
Plastic Bag
Wooden case
In CIVMATS, all of our stainless steel thick-walled pipes 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 pipes together in batches. However, for some special pipes 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
What standard do you follow for the thick-walled SS pipes?
The common standard for stainless steel thick-walled pipe or stainless steel hollow bar we follow is ASTM A511. Unlike fluid-carrying seamless tubes, these SS thick-walled pipes are for use in mechanical applications or as hollow bar for use in the production of hollow components such as, but not limited to nozzles, reducers, and couplings by machining where corrosion-resistant or high-temperature strength is needed.
Can you do polishing to these SS thick-walled pipes?
Yes, we can polish these pipes into 200 to 600 grit as per your requirement. We can also polish 8K/mirror finish.
What's the main grade of thick-walled SS pipes?
MT 321, MT 347, MT 316(L), MT 309S, MT 310S, MT 304(L).
What's your standard package?
we will use thick woven plastic bag to bundle the finished SS pipes together in batches.
What's your standard length?
Random length, 1.5m, 2m, 3m, 4m, 5m, 6m or customized.
What's your main market?
South America, Middle East, Southeast Asia etc.
