Equipment
رؤوس آبار وأشجار إنتاج وصمامات بوابية وصمامات خنق وفق API 6A من 2,000 إلى 20,000 psi، بمستويات PSL 1–4 وفئات مواد AA–HH، مجمّعة ومختبرة في منشأتنا.
Northline designs, assembles and tests API 6A surface wellhead and pressure control equipment for onshore and platform wells. Every assembly is hydrostatically and gas tested in our bunkered test cell and shipped with a full manufacturing record book (MRB), traceability to heat number and third-party witnessed test certificates on request.
Conventional and compact wellheads, solid-block and composite Christmas trees, manual and hydraulic gate valves (2-1/16" to 7-1/16"), adjustable and positive chokes, and refurbished BOP spares. Sour service (NACE MR0175/ISO 15156) trim is standard in HH-NL.
Shell tests at 1.5× rated working pressure, seat tests at rated pressure, and PR2 cycle testing for new designs. Test charts are digitally logged and attached to the MRB.

Pick the API 6A material class from the partial pressure of H2S and the CO2 corrosivity: AA/BB/CC for non-sour (sweet) service with increasing CO2, and DD/EE/FF/HH for sour service (NACE MR0175/ISO 1…
API 6A Product Specification Levels (PSL 1 to 4) define increasing requirements for material testing, NDE, traceability and pressure testing. PSL 3G adds a gas test on top of PSL 3. Higher PSLs are c…
