304 polished pipe is SS 304 (UNS S30400) austenitic stainless steel pipe whose outer surface has been ground and buffed to a smooth, reflective finish. Rico Steel is a manufacturer and supplier of 304 polished pipe in Nigeria, supplying seamless and welded pipe for building, utility, and process applications. We cut every order to your lengths, polish to the grit on your drawing, and ship it with a Material Test Certificate. Contractors in Lagos, Abuja, and Port Harcourt specify the pipe for handrails, water lines, food-plant piping, and oil and gas facilities.
SS 304, also known as UNS S30400 or EN 1.4301, is an 18-8 austenitic stainless steel. It contains 18 to 20% chromium and 8 to 11% nickel, with carbon held at 0.08% maximum. Chromium builds the passive oxide film that resists corrosion. Polishing leaves a smoother surface, so dirt and moisture find fewer places to settle. ASTM A312 sets minimum tensile strength at 515 MPa and minimum yield strength at 205 MPa. Grade 304 therefore serves a wide range of industrial, commercial, and architectural applications, subject to the specific service conditions.

Standard sizes of 304 polished pipe follow the ranges below, and we cut custom diameters and walls to drawing.
| Parameter | Specification |
| Nominal Pipe Size (NPS) | NPS 1/8 to NPS 30 standard sizes (per ASME B36.19M); custom physical ODs available on request |
| Wall thickness | Schedule 5S, 10S, 40S and 80S; custom wall to drawing |
| Length | Single random, double random, 6 m, 12 m, or cut length |
| Construction | Seamless and welded |
| Surface finish | 180-grit satin, 320-grit, and mirror finish |
| Shape and ends | Round, square, and rectangular tubes; plain, bevelled, or threaded ends |
| Standards | ASTM A312, ASTM A269, ASTM A554, ASME B36.19 |
Common 304 polished pipe configurations for Nigerian projects include seamless and welded construction, round pipe, and ornamental or decorative products.
SS 304 seamless polished pipe is pierced from a solid billet, so it has no weld seam. Oil and gas lines in the Niger Delta specify it for that reason.
Welded polished pipe starts as a rolled strip. The seam is welded, annealed, and then polished flush with the surrounding surface. It costs less than seamless pipe in the same size, which makes it the usual pick for water lines, structural runs, and handrails.
Handrails, balustrades, gate frames and canopy posts use ornamental polished pipe. ASTM A554 covers this tubing, and the walls run lighter than process pipe.
Round is the most common pipe form, with dimensions selected to suit the applicable piping components, couplings, or clamps.
Mirror or brushed finishes define decorative polished pipe, and appearance drives the choice. Hotel lobbies, malls, and showrooms use it for columns and display frames.

Six characteristics define how 304 polished pipe performs on site.
304 polished pipe is used in six sectors in Nigeria:
Every order follows the product standard named on your purchase order. Our inspection can cover the following checks, depending on the applicable product standard and order requirements:
Start with the application, then confirm grade, diameter and wall thickness, manufacturing method, surface finish, operating environment, applicable standard and documentation. Seamless pipe suits pressure service, while welded pipe suits structural and decorative runs. Chloride-heavy service may favor SS 316/316L because of its molybdenum content, while SS 304 can be suitable for many sheltered and indoor environments. Name the testing and certificate requirements on the enquiry.
SS 304 polished pipe combines a corrosion-resistant 18-8 chemistry with a finish that serves both architects and plant engineers. Matching diameter, wall, finish and standard to the intended service gives the longest working life. Send us your size list, required standard, finish, and quantity for a quotation.
Five common configurations are available: seamless, welded, ornamental, round, and decorative polished pipe.
Yes. We at Rico Steel supply seamless and Welded 304 Polished Pipe to Nigerian buyers with a Material Test Certificate.
Sizes follow ASME B36.19 from NPS 1/8 to NPS 30, in Schedule 5S, 10S, 40S and 80S. Custom diameters and walls are cut to drawing.
ASTM A312 covers seamless and welded process pipe, and ASTM A554 covers welded ornamental and mechanical tubing. ASME B36.19 sets the dimensions.
Architectural handrails, water lines, food plants, oil and gas utility lines and commercial interiors account for most demand.
Yes. Sheltered coastal sites suit SS 304 when the surface is rinsed and cleaned on a schedule. Direct salt spray and lagoon splash zones call for SS 316.
