This 29 1/2" diverter from Drilltech Manufacturing Co., Ltd. is engineered for offshore drilling applications, providing a critical barrier against wellbore pressure surges. The unit is rated for a working pressure of 500 psi and features a top connection compliant with ASME B16.47 Series A standards, ensuring compatibility with offshore rig piping systems. Its robust construction is designed to withstand corrosive marine environments and extreme temperature fluctuations.
The diverter’s primary function is blowout prevention, redirecting fluid flow away from the rig floor during uncontrolled well conditions. Typical diverter systems in offshore use include a bore size range of 13 5/8" to 36", with 29 1/2" being a common mid-range option for deepwater rigs. The housing is usually fabricated from carbon steel or low-alloy steel, with internal components coated for abrasion resistance.
This equipment is primarily used by drilling contractors and service companies operating in offshore oil and gas fields. It is essential for maintaining well control during the initial phases of drilling, particularly in high-pressure or high-temperature (HPHT) environments. Packaging for international shipment is typically designed to meet DNV 2.7-1 or equivalent standards for offshore containerisation, ensuring safe transit to rig sites.

Before ordering this diverter from Drilltech Manufacturing Co., Ltd., verify that the ASME B16.47 Series A top connection matches your rig’s piping specifications. Confirm the material grade of the housing and internal components, as these must align with your well’s fluid composition and environmental conditions. Request third-party inspection reports for pressure testing and material certifications to ensure compliance with API Spec 16A.
Logistics for offshore diverters require specialised handling due to their size and weight. Confirm that the supplier can provide DNV 2.7-1 compliant packaging for sea freight, and check if the Incoterms offered (such as FOB or CIF) include rig-site delivery or port-side pickup. Lead times for custom diverters can exceed 90 days, so align production schedules with your drilling timeline to avoid delays.
Quality checks should include a full dimensional inspection of the bore and connections, as well as a hydrostatic pressure test to the rated 500 psi. Inspect the internal coatings for uniformity and thickness, and verify that all welds are non-destructively tested (NDT) to API standards. Request documentation for traceability of materials, including mill test certificates for the steel used in the housing.
