The BOP (Blowout Preventer) from Xi'an Longer Machinery Co., Ltd. is a pressure control device used in oil and gas drilling operations to seal, control, and monitor wellbore pressure. Available in single and double ram configurations, it is engineered for high-pressure environments and compact installation on rig platforms. The source confirms design intent but provides no pressure ratings, materials, or certifications.
These units are typically constructed from forged steel alloys such as ASTM A105 or 4140, with elastomeric seals rated for temperatures up to 120°C. The double ram variant includes both pipe ram and blind ram functions, allowing operation under varying well conditions. Compact design is a noted feature, reducing the footprint on space-constrained offshore rigs, a common requirement in modern drilling setups.
The product is targeted at drilling contractors, offshore service providers, and equipment distributors serving the Middle East, Southeast Asia, and Latin American markets. Buyers require units compliant with API 53 standards for blowout preventers. Trade terms mentioned include FOB and CIF, with payment options of L/C and T/T, though exact MOQ and lead time are not stated in the source.

Before ordering, verify the BOP’s API 53 class rating, material certification for the body and seals, and pressure test records. Request physical samples of the ram seals and flange faces to assess quality. Do not accept units without third-party inspection reports from an approved agency such as SGS or Bureau Veritas.
Confirm lead time is based on production schedule, not stock availability, as BOPs are custom-built. Typical lead time ranges from 8 to 16 weeks. Payment terms are likely T/T 50% advance with balance before shipment, or L/C at sight. Ensure Incoterms are clearly defined as FOB Qingdao or CIF destination, and that insurance covers transit risks for high-value equipment.
Conduct a pre-shipment inspection focusing on hydraulic leak tests, ram movement smoothness, and flange alignment. Use a torque wrench to verify bolt tension on casing flanges. Retain a sample of the seal material and request a batch traceability number. Ensure all documentation is in English and includes CE or API marking if required for your region.
