Application:
Copper pipes are used in a variety of industries; including marine environment, power generation, offshore, oil and gas, and defense.
The drawn copper pipe has both cold working and hot working performance, has the highest degree of seawater corrosion and scouring ability, and high strength. Typical users are distillation and desalination plants, as well as marine coolers and heat exchangers.
Using vacuum melting technology, the quality of the pipe is high: the chemical composition is stable, the size is accurate, and the inner and outer surfaces are clean, smooth and bright. Good mechanical properties-no pores, cracks, pinhole leakage and other defects.
Mechanical Testing Such as Tensile of Area:
Hardness Test
Chemical Analysis – Spectro Analysis
Positive Material Identification – PMI Testing
Flattening Test
Micro and MacroTest
Pitting Resistance Test
Flaring Test
Intergranular Corrosion (IGC) Test
