Specification table of stainless steel BA / EP pipe (non-standard customization) | ||||||||
Due to the high concentration of microelectronics and the high cleaning requirements of pharmaceutical and bioengineering teams, the surface finish and cleanliness of the inner wall of the pipeline bearing the transmission medium are required to be high in the production process, so as to ensure the cleanliness of the ultra-pure medium used in the electronic industry and that the medium in the transmission pipeline of pharmaceutical bioengineering does not accumulate and produce bacteria.
In order to meet this requirement, it is necessary to use high finish and high cleanliness of inner surface, electrolytic internal polishing or mechanical grinding internal polishing stainless steel pipe (EP / BA pipe for short) and clean technology
In order to meet this requirement, it is necessary to use high finish and high cleanliness of inner surface, electrolytic internal polishing or mechanical grinding internal polishing stainless steel pipe (EP / BA pipe for short) and clean technology
1. Steel pipe material 316L, (sulfur control (s: 0.005-0.012))
2. The production standard is in accordance with China GB standard (Ni > 10) (conventional), and China Baosteel material (Ni > 12) (customized)
3. Ordinary Ba roughness of steel pipe Ra0 Below 5, clean Ba roughness Ra0 Below 4, the roughness of clean EP is Ra0 Below 25
4. Ordinary Ba = bare package, deburring at both ends (non flat mouth) package Ba = external throwing, flat mouth, single-layer bagging of each pipe cap, clean Ba = external throwing, flat mouth, ultra clean cleaning, dust-free clean room packaging, two caps and single-layer bagging after filling with nitrogen
5. Clean EP is protected by an extra layer of outer bag according to the cleaning process and packaging method of clean Ba after electrolytic polishing.

Why Choose Us
quality raw materials
The refined steel strips of Baosteel and TISCO, which are well-known steel mills in China, are used as raw materials to ensure that the stability of welded pipes meets national standards such as national standards, European standards and American standards.
surface treatment
A variety of surface treatments are available: sanding, wire drawing, bright light, etc. The polishing brightness of the welded pipe surface can be up to 800# and the internal and external surfaces of the welded pipe are free of delamination, crack, folding, strain, trachoma and concave convex points.
Inner wall treatment
The welded pipe shall be full, straight and free from shadow
The whole process is mechanically polished with a thousand blade wheel from coarse to fine, with high-precision polishing. The internal polishing Ra value can be less than 0.2um, smooth and traceless, meeting the needs of various inner walls.

Product accuracy
Solid thickness sales, accurate tolerance, round tube is true, square tube is square, customized tube size can be controlled, tube diameter is within ± 0.1mm, and thickness tolerance is within ± 0.5mm. The diagonal angle of square tube is within ± 0.2mm.
performance testing
Welded pipe has high weld bead strength, surface corrosion resistance and good processing performance. Pure nitrogen protection welding, pure hydrogen annealing protection. According to the strength test, the compressive load of the welded pipe can reach 700 kg, the tension can reach more than 690mpa, the flared rate can reach more than 30%, and the pipe will not burst through the test of pipe expansion, pipe contraction, crimping, bending and fan pressing. 1000h salt spray test: the surface is free of corrosion.
