The 40mm diameter stainless steel pipe is often referred to as the "Golden Standard" in the fluid transport and structural engineering sectors. Its precise diameter offers the ideal balance between flow capacity and structural rigidity, making it indispensable in the global industrial chain. Currently, the international market is seeing a surge in demand for high-grade alloys like AISI 304, 316L, and Duplex 2205 for this specific dimension.
In the CIS region (Россия, Казахстан, Беларусь), where "Компания" (Company) procurement standards are rigorous, 40mm stainless steel pipes are heavily utilized in cryogenic applications and high-pressure steam lines. Our factory has optimized production lines to meet GOST and ASTM standards simultaneously, ensuring seamless integration into international projects. The rise of Green Energy and Hydrogen technology has further accelerated the need for 40mm pipes that can withstand high-pressure environments without degradation.

We provide multiple finish options including No.1, 2B, BA, Hairline, and Mirror Polishing (8K). For 40mm pipes used in architectural handrails or food-grade machinery, our surface roughness (Ra) is strictly controlled within 0.4μm.
By using premium raw materials, we ensure our 40mm pipes have superior corrosion resistance. Our 316L pipes contain at least 2.0% Molybdenum, providing exceptional protection against pitting in marine and chemical environments.
Compliance is our priority. We adhere to ASTM A312, A269, A213, EN 10217-7, and ISO 9001:2015. Every batch is tested with PMI (Positive Material Identification) and hydrostatic pressure tests.
Our Wuxi factory utilizes intelligent monitoring systems to track the wall thickness and concentricity of every 40mm pipe, reducing material waste and ensuring 100% dimensional accuracy for automated welding processes.
OES Metal, established in 2014, is a famous professional steel company specialized in producing. Our factory is located in Wuxi, Jiangsu, with more than 100 employees and a 5000 square meter factory, capable of running platform processing equipment every day for manufacturing, cutting, packaging, and other work.
OES Steel has exported thousands of tons of high-quality STEEL to North America, South America, Gulf countries, Africa, CIS, and Southeast Asia. The products have been exported to more than 50 countries and regions. You will be impressed by our superior quality control services in technology, packaging, and delivery.

As a leading China 40mm Stainless Steel Pipe Factory, OES Metal is pivoting towards Eco-Friendly Manufacturing. The global steel industry is transitioning to "Green Steel" initiatives. We have implemented water-recycling systems in our polishing units and energy-efficient induction furnaces for our annealing processes. This not only reduces the carbon footprint but also lowers the production cost, a benefit we pass directly to our "Компания" partners worldwide.
Global procurement needs are shifting from "Price-Only" to "Value-Chain Stability." Buyers in Europe and North America are now prioritizing suppliers with localized warehousing capabilities and fast logistics. Our proximity to the Port of Shanghai allows us to offer 40mm pipes with a lead time 20% faster than inland factories. Furthermore, our ability to provide customized ODM/OEM services for 40mm tubing—such as custom lengths, laser marking, and specialized bundle packaging—makes us the preferred vendor for high-end industrial projects.
