1. Product Overview

This is an ASTM certified high-performance alloy seamless steel pipe, professionally customized for low-pressure fluid drilling pipeline systems. Adopting hot rolling and cold drawing seamless forming technology, the pipe features compact metallographic structure, uniform wall thickness and excellent airtightness. Strictly compliant with ASTM industry standards, it effectively resists mild corrosion, low-temperature fatigue and fluid impact, delivering stable and durable performance for long-distance low-pressure fluid transportation in drilling projects.

2. Product Features

Standard Certification: Fully certified by ASTM industrial standards, consistent with international drilling pipeline specifications.

Superior Material: Premium chrome-moly alloy steel with optimized chemical composition for enhanced toughness and pressure resistance.

Seamless Structure: No welding seam, avoiding fluid leakage and reducing pipeline failure rate.

Low-Pressure Adaptability: Stable performance under long-term low-pressure fluid circulation, anti-scaling and anti-impurity erosion.

Easy Processing: Support cutting, threading and bending, convenient for on-site drilling pipeline assembly.
