Incoloy825 tube For Making Heating Elements

Incoloy825 tube:

1, Executive Standard: ASTM B704

2,Application: heating elements

3,Material: Incoloy825 (UNS N8825, 2.4621, ALLOY825)

4, Specification: Outside diameter: 6.0mm-25.4mm, Wall thickness: 0.3mm-2.0mm, Length: according to your requirements.

5,Tolerance: As per executive standard requirements, for those tubes which require high precision, we can make according to your own tech requirements.

6,Heat treatment: In-line bright annealing.

7,Information: Beside the normal executive standard, we could also make the Incoloy840 welded tubing according to your own requirements, such as wall thickness tolerance, hardness, surface requirements and etc by designing different technical requirements and production technology, try our best to support you.

Strict quality control system ensures the high quality Incoloy825 welded tube:

1, Raw material: Testing principal component strip burr and thickness according to furnace number or materials of each roll.

2, Tubing welding: Testing length, outside diameter, spherical degree, welding seam and appearance for 50tubes/batch/set or 30 minutes/one time/set

3, Detecting: ALL.

4, Hydraulic press(Air Press): Testing all tubes by 10 MPa/holding 10s or 1 MPa/holding 10s.

5, Final tubes: Testing length, outside diameter, spherical degree, welding seam, appearance and burrs at two ends for all tubes.

6, Mechanical features: Testing flaring, flattening, reverse bending, tensile strength, yield strength and elongation for 200tubes/bath/set.
