304 stainless steel ERW pipe is an SS 304 (UNS S30400) product made from a flat metal strip. Rollers form this steel strip into a tubular section before joining the edges together. Electric resistance welding fuses the metal securely without using any external filler material during production. We cut to your lengths, finish the surface and ends to the drawing, and ship with a Material Test Certificate. Buyers in Muscat, Sohar, Salalah and Duqm use the pipe for water systems, building frames, food plants and industrial fabrication.
SS 304 ERW pipe is welded 18-8 austenitic stainless pipe with 18 to 20% chromium and 8 to 11% nickel. The grade carries three common designations: UNS S30400, EN 1.4301 and JIS SUS 304. In the ERW process, cold-rolled strip passes through forming rolls and closes into a round section. High-frequency current generates heat at the strip edges, which are then brought together under pressure to form the longitudinal weld. The weld bead is then trimmed, and the pipe is annealed and sized.

Our standard range is listed below, and custom sizes are rolled to order.
| Parameter | Specification |
| Outside diameter | 6 mm to 610 mm (custom OD on request) |
| Wall thickness | 0.5 mm to 12 mm; Schedule 5S, 10S and 40S |
| Length | 6 m standard, random length or cut length |
| Pipe ends | Plain, bevelled or threaded |
| Surface finish | Mill, satin, polished or BA |
| Standards | ASTM A312, ASTM A554, ASTM A269, ASME B36.19 |
Common 304 ERW configurations for Omani projects include round pipe, polished and decorative products, large-diameter pipe, and square or rectangular sections.
Round ERW pipe is the base product. Water lines, process headers and structural frames all use it, and it takes standard fittings without adaptation.
Polished ERW pipe is ground and buffed after welding until the weld line disappears into the surface. Handrails and lobby fittings in Muscat specify it for that reason.
Mirror and brushed finishes define decorative ERW pipe. Hotels, malls and showrooms use it for columns, display frames and partition rails.
Large diameter ERW pipe runs up to 610 mm OD in our range. Drainage headers, water mains and plant utility lines call for it.
Square and rectangular sections suit frames, gates, racks and machine bases. Flat faces simplify welded joints and bolted brackets.

SS 304 ERW pipe is a very reliable and adaptable tubing solution made by continuous cold-forming and electric resistance welding. This fast manufacturing process produces tight dimensional tolerances, superior surface finish and outstanding structural performance for demanding fluid transport and structural applications.
SS 304 ERW pipe supports diverse structural, commercial, and industrial applications across key economic sectors in Oman.
Select from four surface finishes and three end configurations to match specific project requirements.
Each production lot goes through 5 rigorous inspection and testing procedures before final shipment. Strict quality control checks are conducted to ensure all technical specifications and international standards are complied with.
Specify the grade and standard, outside diameter, wall thickness, schedule, length, surface finish, end shape, operating circumstances, and documentation requirements to allow proper pipe selection. In your request, specify which ones you want, such as ASTM A312 for process piping, or ASTM A554 for ornamental, mechanical, and light architectural frameworks. The selection of the grade is based on the operating conditions. The chloride-rich marine or desalination environment requires an SS 316 with 2 to 3 % of molybdenum. SS 304 is used in protected interior systems with reliability.
SS 304 ERW pipe delivers an even wall, reliable welds and a finish range that serves industrial, commercial, and architectural requirements. Choosing the correct size, finish, and specification at the enquiry stage prevents rework on site. Send us the size list and standard for a quotation.
We at Rico Steel supply 6 mm to 610 mm OD with walls from 0.5 mm to 12 mm. Custom sizes are rolled to order.
Water systems, building and architectural frames, food plants, commercial projects, and industrial fabrication account for most demand.
Yes. SS 304 ideal for potable water, drainage, and utility lines. Seawater and brackish water need SS 316 or a duplex grade.
Yes. Sheltered coastal locations suit SS 304 with regular rinsing. Direct salt spray and splash zones call for SS 316.
Plain, bevelled, and threaded ends are available. Bevels are cut to 37.5 degrees for butt welding.
