Flow tube seals use tungsten carbide (TC) or ceramic liners to resist wireline abrasion at 300 ft/min. HVOF-applied TC at 1,400 HV survives 1,000 hours of braided cable. Baker Hughes’ TC tubes with 0.005-inch clearance seal 12,000 psi. Polished Ra 4 μin finish minimizes cable wear. In logging ops, these extend tool life 3x versus steel tubes. https://globalsealstech.com/product-category/oil-gas-seals/oil-free-lubricated-pump-seals/
