High Pressure Seamless Steel Pipe
1. Product Introduction
Our high pressure seamless steel pipes are produced by piercing, hot rolling and cold drawing technology from solid steel billets. There are no welding seams on the pipe body, effectively avoiding leakage risks under high pressure. With superior mechanical properties, high tensile strength and excellent airtight performance, the products can operate safely and stably for a long time under high pressure, high temperature and harsh working conditions.
We supply a full range of carbon steel and alloy steel grades, strictly manufactured in accordance with API 5L, ASTM A106, ASTM A53, EN, DIN and other international standards. Various sizes, wall thicknesses and pipe finishes are available to meet diverse project requirements.
