ASTM a249 a269 S316L small size stainless steel pipe boiler tube piping
Features of BA grade stainless steel pipe 1. Diameter control: tolerance ± 0.05m m (0.1%); 2. Length control: tolerance ± 3mm; 3. Straightness: less than 0.1mm/m; 4. Surface roughness: Ba pipe RA ≤ 0.8 μ m; 5. Concentricity control: tolerance ± 0.02mm; 6. Mechanical property control: hardness HRB (75-80), strength δ B and elongation ψ can be adjusted and controlled; 7. Heat treatment: solid fusion treatment under protective atmosphere. 8. Cleaning: ultrasonic cleaning, with independent intellectual property technology, to ensure its cleanliness; 9. Flow non-destructive testing, ultrasonic testing, hydrostatic testing and other methods, so as to ensure the internal quality of products.
Sanitary stainless steel pipe features: 1) type: stainless steel sanitary pipe, sanitary stainless steel pipe, sanitary stainless steel precision pipe 2) features: high precision pipe; outer diameter limit deviation ± 0.02mm, inner diameter limit deviation ± 0.025mm, inner hole circumference tolerance 0.020mm, outer diameter 1.3mm-3.0mm, wall thickness 0.015mm-0.08mm, full length 1.5mm-7.0mm metal sanitary steel pipe It has high requirements for dimensional accuracy and cleanliness. 3) Processing method: cold rolling, polishing, bright annealing. 4) Surface treatment: bright annealing, cold rolling, manual polishing, mechanical polishing
Sanitary stainless steel pipe, cold-rolled precision stainless steel pipe: Φ 6-133mm × 0.5-8mm. After cold rolling, ± ≤ 0.02-0.04m m, inner wall roughness Ra ≤ 0.8 μ m, inner wall roughness Ra ≤ 0.4-0.6 μ m after polishing, the inner and outer walls are very smooth.
Executive Standards for precision stainless steel pipe and sanitary stainless steel pipe: cold drawn or cold-rolled precision seamless steel pipe (gb3639-83) is used for cold drawn or cold-rolled precision seamless steel pipe with high dimensional accuracy and good surface finish of mechanical structure and hydraulic equipment.
Our heat exchanger tube in stainless steels are suitable for all types of heat exchangers for conveying all types of gases and liquid with extreme low and high temperature requirements, such as sea water coolers, condensers, evaporators, heaters and reheaters.
They are used for heating, re-heating or cooling of gases, air or fluids in an extensive range of industries like chemical processing, aerospace and nuclear power generation, hydro carbon processing and oil refining.
Our heat exchanger tubes are appreciated for the feature such as dimensional accuracy, corrosion resistance, easy installation and smooth finishing.
