Product Introduction
Product Overview
This welded heavy‑weight drill pipe (HWDP) is manufactured by friction welding the joint to the pipe body. The pipe body is made of 1340 steel, while the joint is fabricated from 4137H/4145H steel. While maintaining reliable performance, it offers a more cost‑effective solution. The weld zone undergoes 100% ultrasonic inspection. Standard and custom lengths are available, with hardbanding provided as an option.

Product Description
• Basic Information: Welded heavy‑weight drill pipe (HWDP) is the most common type of heavy‑weight drill pipe, manufactured by friction welding an extra‑long joint to a thick‑walled pipe body. The friction welding process produces a uniform solid‑state bond without the need for filler metal. The pipe body is made from 1340 steel, while the joints are forged from 4137H or 4145H alloy steel. A thickened section in the middle of the pipe body (the intermediate thickened zone) provides additional wear resistance.

• Application scenarios: Suitable for standard drilling operations requiring cost-effective heavy‑weight drill pipe; applicable to vertical and directional wells; serves as the transition section between drill pipe and drill collars; compatible with most conventional drilling applications.
• Product Advantages: More cost-effective than solid heavy‑weight drill pipes; weld zones undergo comprehensive inspection for reliable performance; certified to API 7‑1 standards; equipped as standard with wear‑resistant bands; fast delivery and customizable lengths available.
• Customer Feedback: Widely used in conventional drilling operations; customers highly praise its excellent cost-effectiveness and reliable weld quality.
