Grade S135 Dth Water Well Drill Pipe
The Grade S135 DTH water well drill pipe from Linqing City Ruilong Drill Co., Ltd. is designed for high-pressure down-the-hole (DTH) drilling applications, including water well, mining, and geological exploration. The S135 grade denotes a high-strength steel alloy with a minimum yield strength of 135,000 psi, suitable for deep and abrasive drilling conditions. The pipes are part of the company’s broader range of DTH drilling tools, which also includes hammers and bits for low, medium, and high-pressure systems.
DTH drill pipes are typically manufactured from seamless alloy steel tubes with precision-machined threads and hardened tool joints to withstand torsional stress and wear. Standard outer diameters for S135 DTH pipes range from 60 mm to 152 mm, with wall thicknesses of 6-12 mm depending on the application. The pipes are often coated or treated to resist corrosion and extend service life in harsh underground environments.
These drill pipes are primarily used by contractors in the water well, mining, and construction industries for projects requiring deep penetration into hard rock formations. Common trade terms include FOB or CFR from Chinese ports like Qingdao or Shanghai, with lead times of 4-8 weeks depending on order volume. Buyers often request API or ISO certification for material and performance standards, particularly for critical applications like mineral exploration.

Sourcing Grade S135 Dth Water Well Drill Pipe from Linqing City Ruilong Drill Co., Ltd. - China Import Guide
Before placing an order, confirm the exact specifications of the S135 DTH drill pipes, including outer diameter, wall thickness, and thread type, to ensure compatibility with your DTH hammer and drilling rig. Request the mill test report to verify the material grade and mechanical properties, as these are critical for performance and safety. Check if the supplier can provide API or ISO certification for the pipes, as this is often required for compliance with industry standards.
Clarify the lead time, which can range from 4 to 8 weeks depending on the order volume and customisation requirements. Discuss Incoterms such as FOB or CFR from Chinese ports like Qingdao or Shanghai, and confirm whether the supplier can arrange container loading and customs documentation. Payment terms often include a 30% deposit with the balance due prior to shipment, but this can vary based on the supplier’s policies and the buyer’s credit history.
For quality assurance, insist on a pre-shipment inspection to verify the dimensions, thread integrity, and surface treatment of the drill pipes. Request a third-party inspection report or a certificate of conformity to ensure the pipes meet the specified standards. Additionally, confirm that the supplier can provide all necessary documentation, including certificates of origin, material test reports, and packing lists, to facilitate smooth customs clearance and compliance with your project’s requirements.
