honed hydraulic cylinder tubing,
hydraulic cylinder pipe
EN10305, DIN239, DIN2445, GB/T 3639, GB 8713
OD: 30mm~250mm WT: 0.5mm~18mm Length: according to customer requirement
Tubes are manufactured by seamless process and both hot finished and cold finished are applicable
Tension Test, Flaring Test, Flange Test, Reverse Test, Hardness Test, Hydrostatic or Nondestructive Electric Test
after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium
after cold forming, annealing in non oxidizing medium protective gas
the final heat treatment after cold forming, therefore small steel pipe plastic, the plastic degree does not guarantee
after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain limits cold deformation(bending, flaring)
have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing again
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
100% of our steel tubes are dimensionally checked
100% of our steel tubes are visually checked to assure they have a perfect surface condition and no surface defects.
100% eddy current test and ultrosonic test to eliminate longitudinal and transversal defects.
