Available in a variety of outer diameters, wall thicknesses, and custom lengths, these pipes are manufactured to meet both international and project-specific specifications. Our extensive distribution network enables us to serve key markets across India, the United Arab Emirates (UAE), the Kingdom of Saudi Arabia (KSA), Kuwait, Qatar, the Sultanate of Oman, Iran, and Iraq.

Technical Overview

Alloy steel welded pipes are highly suitable for high-temperature and high-pressure applications, often operating efficiently in environments exceeding 500°C. These pipes exhibit excellent ductility and resilience against stress corrosion cracking, making them ideal for structurally demanding setups. Owing to their ferritic and martensitic properties, they demonstrate rapid hydrogen diffusion under certain electrochemical conditions, especially when exposed to sea water or aggressive chemical media. These alloy steel ASTM A691 and 1.25 1-14 cr Welded pipes are manufactured in a variety of types, including EFW (Electric Fusion Welded) pipes, and conform to ASTM and ASME standards. Their sizes typically range from 1/8" NPS to 36" OD with wall thicknesses between 11 mm and 20 mm, providing robust options for diverse applications.

Applications & Industry Use

Due to their superior strength, dimensional stability, and long service life, alloy steel welded pipes are widely utilized across numerous industries. Common areas of application include offshore oil drilling, petrochemical processing, power generation plants, gas distribution networks, and high-temperature equipment in refineries and steel manufacturing facilities. These pipes are also frequently used in the automotive sector, pressure vessels, heat exchangers, and pharmaceutical equipment. To ensure reliable performance and quality assurance, all pipes undergo stringent testing procedures such as hydrostatic testing, ultrasonic examination, eddy current inspection, Rockwell hardness evaluation, intergranular corrosion testing, and full third-party validation. These rigorous protocols ensure that every product meets the highest standards of industrial reliability and safety.
