Reliable sealing performance:
Sealing ring adopts imported rubber material for increasing pressure bearing capacity and sealing performance. Seal type depends on pressure and application range.
Quick and easy installation：
Design of wing nut and rigid self-lock type ACME thread can be quick makeup and breakout, no special tools required.
Height interchangeability:
All union structures, connection sizes can be matched with international products, English system size; sealing ring of union can be interchanged with SPM and FMC products. Model and pressure and other markings on wing nut are stamp forged once.
Advanced machining and inspection procedures:
High precision CNC machine can process spherical fitting and special tools can machine LP thread. Wing nuts are machined by CNC machines. Welding material and bevel shall comply with API SPEC 16C specifications; For H2S environment, unions are designed and made as per NACE MR 0175 Stress fracturing material of sulfide resistant for oilfield equipment and API RP-14E specifications.
