Metinox Overseas is a leading Stainless Steel 304 EFW Pipe Manufacturer and international exporter, and is well known for quality and precision. Our Stainless Steel 304 EFW Pipe products are made of Electric Fusion Welding process as per ASTM A358 standards making it highly dependable in the industrial projects of high load. The AISI 304 grade is the most general austenitic alloy and is composed of 18 per cent chromium and 8 per cent nickel that offers superior resistance to corrosion in the atmosphere as well as numerous organic and inorganic compounds. These pipes are a perfect substitute of seamless pipes with large diameter usage in both chemical treatment and water treatment. The mechanical characteristics of the 304 EFW pipes have tensile strength of 515 Mpa minimum and yield strength of 205 Mpa. Although the standard is general-purpose 304 is, other standards available to us are 304L which has improved weldability and 304H with increased creep strength at higher temperatures. To maintain the integrity of the welds, Metinox Overseas supplies these pipes in different classes (Class 1 to 5) with complete X-ray tests. We have an international logistic system that delivers in time the high consumption steel products to the USA, Europe, and Middle East, and they are of the high standards as demanded by the modern day engineering.

Features of the SS 304 EFW Pipes
The EFW pipes are an abbreviation of electric fusion welding pipes. This is an electric beam welding. It involves the high-speed motion of the electron beam that guides the impact of the kinetic energy to warm the piece of work, by this the piece of work is melted, that assists in the creation of weld.
This is primarily applied to welding the dissimilar steel welding sheets. The following are some of the salient characteristics of SS 304 EFW Pipes, which have augmented the demand of this product in various industries.
- Good workability
- Abrasion resistance
- Rigid construction
- Low price
- Seamless finish
- Dimensional accuracy
Testing of SS 304 EFW Pipes
Once the production of the product is done, these SS 304 EFW Pipes are then put through a number of standards testing procedures to test and assure the quality of the final product. This is to gain the confidence of our customers in our ability to sustain long term relationships with them. The tests include the PMI test, hardness test, flaring test, flattening test, mechanical test, intergranular resistance test, micro and macro test to mention but a few. All these tests are arranged according to the industry rules.

Frequently Asked Questions (FAQ)
ERW (Electric Resistance Welding) involves heating the edges of the plate in the absence of filler metal via high-frequency current normally in smaller diameters. EFW (Electric Fusion Welding) welds the material by either an electron beam or electric arc which commonly employs filler metal and therefore is suited to large-diameter, heavy-wall pipes.
The type of welding to be used and the level of radiography is defined by the classes (1-5). As an example, Class 1 has double-welded joints and 100 percent radiography whereas Class 2 has double-welded joints and no radiography.
Yes, the EFW pipes produced as per the ASTM A358 are specifically those that are intended to be used in high pressure. They are tested in terms of their strength by hydrostatic test, and Class 1 and 3 are additionally tested by X-ray.
Seamless pipes are not only hard and costly to manufacture in very large sizes (over 24" diam.), but also highly expensive. The EFW pipes provide a cost effective alternative to a large bore pipe without disturbing the mechanical strength or anti corrosion of the 304 alloy.
Absolutely. Grade 304 is food grade and very oxidation resistant. It is widely used as municipal water treatment and transport infrastructure in the world.
