EFW Pipe

Largest EFW Pipe Manufacturers In India, Best EFW Steel Pipes Supplier In Mumbai

Priminox Overseas is a well-known manufacturer, supplier and exporter of EFW Pipes (Electric Fusion Welded Pipes) located in Mumbai, India. As an industry leader and pioneer of new technologies, our commitment is on delivering the best piping systems to clients across the world. Thus, EFW steel pipes are ideal for use in many industries since they are strong, durable, and perform best.

EFW pipes are welded pipes which are formed by heating the edges of the steel plate and without any additional filler material. This method allows for a very continuous and strong pipe structure thus making it suitable for challenging applications. EFW pipes are manufactured in stainless steel, duplex steel, carbon steel, and alloy steel with a chosen material depending on the pipe’s application in an industry.

EFW pipes made from stainless steel have high corrosion strength and can therefore be used in chemical processing, oil and gas as well as in power generation. Carbon steel EFW pipes possess features like higher tensile strength and greater levels of hardness and are used mostly in construction and structural industries. Alloy steel EFW pipes offer improved mechanical properties and therefore they are suitable to work under high pressure and high temperature conditions.

The weld quality of our EFW pipes is excellent so is the thickness of the wall of the pipes and the dimensions of the pipes. They are intended for use under high pressure and have high corrosion, oxidation and wear immune properties. These features make our EFW pipes useful in various applications such as, for the transportation of fluids and gases, structural member in constructions and buildings, and in heat exchanging apparatuses as well as boilers.

Quality is always a top priority and a strict quality control system is employed to guarantee that the EFW pipes produced are to international standards. The production facility of our company has sophisticated technology and equipment which help make EFW pipes of superior quality. In addition to the above, we follow strict quality management measures across all the production process from purchase of raw material to the final inspection of the product to enhance product reliability and performance.

EFW Pipe Specification

The ASTM standards for EFW (Electric-Fusion Welded) pipes are available for various uses and are made of different materials. The following is a comparison of these specifications in detail.

1. ASTM A358 EFW Pipe

Material & Construction: Electric Fusion Welded (EFW)austenitic chromium-nickel stainless steel pipes
Grades: Commonly produced in Grades 304, 304L, 316, and 316L.
Uses: High-pressure or corrosive environments, such as in chemical plants, refineries, and power stations.
Advantages:

Excellent corrosion resistance.
Ideal for environments with high temperatures and pressures.

Manufacturing: Includes multiple classes (Class 1 to 5) to specify additional tests and requirements based on end-use.
Applications: Suitable for corrosive environments and high-temperature service.
Typical Composition: Contains 18% chromium and 8% nickel; Class 316L includes molybdenum for enhanced corrosion resistance.
Sizes and Thickness: Available in sizes ranging from 8 inches to 72 inches with thicknesses from 3mm to 60mm

2. ASTM A672 EFW Pipe

Material & Construction: EFW steel pipes made from pressure vessel-quality plates.
Grades: Based on the type of plate material used, including carbon and low-alloy steels.
Uses: Moderate to high-pressure services like boilers, heat exchangers, and industrial piping systems.
Advantages:

Excellent weldability and toughness.
Tailored for applications where cost-efficiency is essential compared to stainless steel.

Manufacturing: Requires specific weld procedures and heat treatments based on application demands.
Applications: Ideal for high-pressure applications in industries like oil and gas.
Welding Requirements: Requires weld samples from longer lengths (500 ft) with provisions for additional samples if the original fails.

3. ASTM A671 Pipe

Material & Construction: Electric Fusion Welded carbon and low-alloy steel pipes for atmospheric and lower temperature applications.
Grades: Similar to A672 but with broader options for thickness and length.
Uses: Pressure piping at moderate temperatures and pressures in industries like oil, gas, and petrochemicals.
Advantages:

Durable and cost-effective for medium-pressure systems.
Available in customised configurations for specific applications.

Manufacturing: Offers more flexibility with weld quality tests based on user specifications.
Applications: Used primarily for low-pressure service at ambient temperatures.
Welding Requirements: Requires weld samples drawn from shorter lengths (200 ft) without provisions for rejected welds.

4. ASTM A928 Pipe

Material & Construction: Duplex and super duplex stainless steel EFW pipes.
Grades: Often includes 2205 (UNS S31803) and 2507 (UNS S32750).
Uses: Critical environments requiring superior corrosion resistance, such as seawater systems, desalination plants, and chemical industries.
Advantages:

Excellent pitting and stress corrosion resistance.
Higher strength compared to austenitic stainless steel.

Manufacturing: Focuses on duplex metallurgy, which provides better mechanical properties.
Applications: Typically used in power generation and petrochemical industries where high strength is required.
