Drill pipe dual wiper 2-7/8"
The dual wiper for 2-7/8 inch drill pipe is a rubber sealing component designed to remove drilling fluid residue from the outer surface of tubulars during tripping operations. It features an internal steel skeleton to prevent deformation under pressure and is constructed from butyronitrile rubber for resistance to water-based and oil-based mud systems. The wiper is sized to fit snugly over the drill pipe body to ensure effective cleaning without excessive friction.
The rubber compound has a hardness range of 8 to 95 ±5 Shore A, with a tolerance of ±3 Shore A, allowing customization for different mud viscosities and operational temperatures. The material resists cutting, abrasion, and high-temperature degradation, making it suitable for use in deep wells where temperatures exceed 120°C. The steel core is typically made from carbon steel, plated to prevent corrosion from exposure to drilling fluids.
These wipers are used by drilling crews in onshore and offshore operations to prevent fluid backflow and reduce corrosion risk on drill pipe threads. Buyers include drilling contractors in Southeast Asia, Africa, and Latin America who require reliable, cost-effective components for daily operations. Orders are typically placed in batches of 50 to 200 units, with packaging in sealed polyethylene bags and cartons. Lead time and minimum order quantities are not specified and must be confirmed with the supplier.

Sourcing Drill pipe dual wiper 2-7/8" from Dongying Lake Petroleum Technology Co., Ltd - China Import Guide
Before ordering, confirm the exact rubber compound formulation and its compatibility with your drilling fluid type. Request a material safety data sheet and test reports for hardness, tensile strength, and fluid resistance. Verify the inner diameter tolerance against your drill pipe’s actual outer diameter, as variations in pipe manufacturing can affect fit. Do not accept wipers without batch-specific quality documentation.
Confirm Incoterms - commonly FOB Qingdao - and whether the supplier includes export documentation such as commercial invoice, packing list, and certificate of origin. Lead time is not stated; buyers must request production scheduling and confirm whether the order is from stock or requires mold setup. Payment terms are typically 30% advance, 70% against shipping documents, but must be negotiated directly.
Upon receipt, inspect each wiper for surface defects, consistent color, and absence of mold lines or flash. Measure inner diameter with a caliper to confirm fit within ±0.25 mm tolerance. Perform a hardness test on a sample using a Shore A durometer. Retain samples for future comparison and request batch traceability numbers for each shipment to support quality audits.
