Products

Welded Steel Pipe

Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or steel strip after being crimped and welded. Welded steel pipes have simple production process, high production efficiency, many varieties and specifications.Welded steel pipes for low-pressure fluid transportation (API 5L) are also known as general welded pipes, commonly known as black pipes. Welded steel pipe for conveying general lower pressure fluids such as water, gas, air, oil and heating steam and other purposes. Super Steel Manufacturing can offer SAWL/LSAW Steel Pipe, SSAW Steel Pipe, EFW/ERW Steel Pipe in standard size or as customer’s requirement.

Seamless Steel Pipe

Seamless pipe made of a single piece of metal with no seams on the surface is called a seamless steel pipe. According to the production method, the seamless pipe is divided into a hot rolled pipe, a cold rolled pipe, a cold drawn pipe, an extruded pipe, a top pipe, and the like. According to the shape of the section, the seamless steel pipe is divided into two types: a circular shape and an irregular shape, and the shaped pipe has a square shape, an elliptical shape and the like. The maximum diameter is 650mm and the minimum diameter is 0.3mm. Seamless steel pipe is mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural steel pipe for automobile, tractor and aviation.

Hollow Section

A hollow structural section (HSS) is a type of metal profile with a hollow cross section. The steel hollow section is made up of various material welded structural hollow sections for multiple purposes. No matter building construction, or spare parts manufacturing, even working parts construction. It is also used in these projects. Here are products Mild Steel Square Tube, Mild Steel Rectangular Tube, Stainless Steel Square Tube, Stainless Steel Rectangular Tube.

Coated Steel Pipe

Coated steel pipe means the pipe that is by the processing after the corrosion, which can effectively prevent or slow the steel pipe occurs in the course of transport and chemical or electrochemical reaction corrosion phenomena. Coated steel pipe can effectively prevent or slow down the corrosion of steel pipes to extend service life and reduce operating costs pipe. Super Steel Manufacturing is a supplier that can offer Galvanized Steel Pipe, FBE Coated Pipe, Epoxy Coated Pipe, 3LPE/3PE Coated Pipe.

Finned Steel Tube

Fin tubes are a type of heat exchanger that is used in many different industries. These tubes have a finned surface, which increases their surface area and allows them to transfer heat more efficiently. This makes them ideal for applications where high heat transfer rates are required, such as in power plants and refrigeration systems. Fin tubes are made from a variety of materials, including copper, aluminum, and stainless steel. They are available in a range of sizes and shapes and can be customized to meet the specific needs of each application.

Pipe Fittings

Pipe Fittings are defined as the piping components that help in pipe routing for directional changes, size changes, and branch connections. Super Steel is one of the top supplier of Flange, Elbow / Reducer / Tee / Cap / Bend and Valves, which are widely used in both the piping and plumbing industries.

Steel Plate & Beam

Steel plates normally stand for steel plates 6mm or thicker and are made by hot-rolling a semiproduct slab 200mm or thicker and then through follow-up processes such as cooling or heat treatment. Steel plates ramify into products for general structure, welding, boiler or large-diameter steel pipes depending on material. Super Steel Manufacturing can offer Alloy Steel Plate, Carbon Steel Plate, Nickel Alloy Sheet/Plate, Stainless Steel Plate,C Channel, H/I Beam,Steel Bar.
