Professional Design Incoloy 825 Hydraulic Control Line Tube - Monel 400 Hydraulic Control Line Tube – MEILONG

Product introduction

● Each one tubing coil is a completely continuous length without orbital welds.

● Each one tubing coil is hydrostatic tested with a targeted pressure.

● The test can be witnessed on site by the third party inspectors (SGS, BV, DNV).

● Other tests are eddy current test, chemicals, flattening, flaring, tensile, yield, elongation, hardness for the material quality.

Tubing Process and Packing

1. Seamless: pierced, redrawn, annealed (multi-pass circulation process)

2. Welded: longitudinally welded, redrawn, annealed (multi-pass circulation process)

3. Packing: Tubing is level wound coiled on the metal / wooden drums or spools.

4. All drums or spools are packed in wooden crates for easy logistic operation.

Alloy Feature

Monel 400 is a nickel-copper alloy (about 67% Ni – 23% Cu) that is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. Alloy 400 is a solid solution alloy that can only be hardened by cold working. This nickel alloy exhibits characteristics like good corrosion resistance, good weldability and high strength. A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions. This nickel alloy is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated.
