D4 / T3 Bright Annealed Stainless Steel Tubes ASTM A213 ASTM A269 EN10216-5 TC1
Bright annealed stainless steel tubes as per following standard:
ASTM A213 ASTM A269 EN10216-5 TC-1
Tolerance:D4/T3 (±0.5%,±0.1 min)/(±10%,±0.2 min)
NDT Tests:Eddy Current or Hydraulic Test or UT
Heat treatment on tubes: Bright Annealed
304 stainless steel pipe tube
Quality Assurance: ISO 9001&PED 97/23/EC certificated with 100% traceability on all instrument tubes and material test reports(EN 10204/3.1B)accompany every shipment upon request.
Application:
Instrument Tubing
Chromatography tubing
Hydraulic Tubing
High Pressure Tubing
Cleaned Tubing
Multi Core Tubing
Why choose bright annealed tube?
1.Superior Surface Finish
The traditional annealing :Open furnace---Oxygen atmosphere---form Scale, tarnish the material,For more than 12m tubes this method is hard to clean inner surface.
A special bright annealing:Closed furnace---Intert atmosphere use noble gases(Nitrogen and argon)Preventing Oxygen to contact with marterial ---Surface finish is clean,bright and precision,which is an excellent starting point for further process,like electro-polishing and mechanical polishing. For more than 12m tubes,this method is much cleaner smoother on both inner and outer surface.
2.Better Mechanical Property
The temperature of furnace can reach more than 1350℃,and the tolerance for setting and real temperature can be controlled whithin +/-2℃,which is impossible for the traditional annealing.
3.Perfect Inspection Method And Inspection Equipment
100%PMI test
100%Hydraulic test
100%Inner cleaned by sponge
100%Dimension test
100%Surface test
Quality of precision drawn tubing is same to precision rolling.
4.More Precision Dimension
Advanced cold drawn technology from Japan and Korean,Making the close dimension controls.
QUALITY CONTROL
1~ Incoming Raw Material Inspection
2~ Raw Material Segregation to avoid steel grade mix-up
3~ Heating and Hammering End for Cold Drawing
4~ Cold Drawing and Cold Rolling, on line inspection
5~ Heat Treatment, +A, +SRA, +LC, +N, Q+T
6~ Straightening-Cutting to specified length-Finished Measuring Inspection
7~ Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc
8~ Packing and Stocking.
