2-3/8″ EU API 5CT Thread Protector | OCTG Tubing Accessories
2-3/8 EU thread protector, a critical protective accessory for oil and gas well OCTG tubing.
It is designed for EU (External Upset) tubing, fully compliant with API 5CT industry specifications. Standard size 2-3/8 inch, made of outer steel inner plastic composite material. The outer steel layer provides impact resistance, while the inner plastic prevents thread scratch and corrosion. It shields tubing threads from impact, rust and damage during transportation and storage, effectively keeps the thread intact to guarantee smooth pipe connection on site.
We adopt high-strength steel and wear-resistant plastic raw materials, with strict full inspection for every protector to satisfy long-term oilfield operation demands.
