1. Structure: There
is a deposition of tungsten alloy layer on the inner and outer
walls of general API standard pipes or special premium thread
tubing.
2. Performance Indicators
Tungsten Alloy Layer and Backing Material Binding
Force: According to GB/T5270-2005 testing, the
tungsten alloy layer does not crack or peel off.
Appearance: Uniformly bright, showing silvery
white
Thickness of Tungsten Alloy
Layer: 40-60μm
Hardness of Tungsten Alloy
Layer: 560-640HV
Special Premium Thread Tubing: Hydrostatic
pressure: 95MPa, load maintaining for 30 minutes, without
leakage.
Gas seal: 70MPa, load maintaining for 15 minutes,
without leakage.
