Pipe Coupler
The Dth Group offers a pipe coupler designed for down‑the‑hole drilling and borehole projects. It is fabricated from carbon steel or alloy steel meeting Grade ASTM A519. The coupler provides fire‑resistant properties and low thermal conductivity to maintain structural integrity under high‑pressure downhole conditions. Its threaded or flanged connection style suits water‑well, mineral‑exploration and oil‑and‑gas drilling assemblies.
Carbon steel offers strength while alloy variants improve corrosion resistance, a common trade‑off in the drilling industry. Typical pipe couplers of this class are rated to 150 bar and conform to API 5L standards, which Dth Group follows as a typical practice. The product’s dimensions are customised per client, but standard bore sizes range from DN 50 to DN 200, a typical size envelope for down‑hole tooling. Industry practice favours a surface finish of mill‑scale or optional epoxy coating to enhance durability.
The coupler is sold for bulk import and export, with packaging usually in wooden crates of 100 units. Buyers such as drilling contractors, mining firms and oil‑field service companies typically request FOB or CIF terms; exact incoterms should be confirmed with the supplier. Minimum order quantities and lead times are not disclosed in the listing and should be verified directly. Payment is commonly arranged via T/T or L/C, subject to agreement.

Sourcing Pipe Coupler from Dth Group - Sri Lanka Import Guide
Before placing an order, importers should verify that the coupler material matches the specified ASTM A519 grade and that fire‑resistant properties are documented. Request a mill test report and, if available, a material certification to confirm composition. Confirm the exact dimensions and pressure rating required for your drilling equipment, as the supplier offers custom sizes. Ensure that the supplier can provide any necessary export licences for steel products from Sri Lanka.
Logistics considerations include agreeing on the incoterm, with FOB Port of Colombo or CIF Colombo being common for Sri Lankan exporters. Ask the supplier for the estimated lead time, which may vary with custom sizing and current production schedules. Clarify the packaging details, such as crate dimensions and whether pallets are used, to plan warehouse handling. Discuss payment terms, typically T/T in advance or L/C at sight, and any bank guarantees required.
Quality assurance should involve a third‑party inspection before shipment, focusing on dimensional checks, pressure testing and visual inspection for coating integrity. Request the supplier’s ISO 9001 certificate and any relevant fire‑resistance test reports. Arrange for a post‑shipment documentary inspection, including the commercial invoice, packing list and certificate of origin, to satisfy customs clearance in the destination country.
