Seamless Oil Tubing for Oilfield is installed inside the casing as the production or injection flow path for oil, gas and formation water. It is smaller in diameter than casing and can be removed and replaced during well servicing. We supply tubing in common API 5CT grades, sizes and thread connections for conventional, deep, sour and high-pressure oil and gas wells.

Oilfield seamless casing pipe is used in oil and gas wells to support the wellbore, isolate different formations and provide a controlled path for drilling and production operations. We supply casing in J55, K55, N80, L80, P110 and Q125 grades, with available sizes, thread connections and lengths matched to well design requirements.

Zinc-Aluminum-Magnesium Coated Rectangular Steel Tube combines a rectangular hollow section with a zinc-aluminum-magnesium protective coating. The flat-sided section is useful where the tube needs to fit closely against walls, frames, panels or equipment surfaces, while the coating is intended for outdoor and humid service. Common applications include photovoltaic structures, curtain wall frames, equipment racks, greenhouse structures and municipal steelwork.

Zinc-Aluminum-Magnesium Coated Square Steel Tube combines a square hollow steel section with a zinc-aluminum-magnesium protective coating. It is mainly used where the steel section needs both structural strength and long-term corrosion protection, including solar mounting systems, outdoor steel structures, equipment frames, fences and other exposed applications.

Zinc-Aluminum-Magnesium Coated Round Steel Pipe is designed for outdoor steel structures, photovoltaic systems, agricultural structures, guardrails and other applications where corrosion protection and a circular steel section are both required. The round section distributes loads around the circumference and works well for curved structures, handrails, arches and tubular supports.

Hot-Dip Galvanized Spiral Steel Pipe is manufactured from hot-rolled steel strip through spiral forming, double-sided submerged arc welding and subsequent hot-dip galvanizing. It is designed for large-diameter water transmission, drainage, foundation, industrial piping and outdoor projects where both structural strength and corrosion protection are required. Available in DN200–DN3000, with Q235B and Q355B grades, 3–20 mm wall thickness and customized lengths and end processing.
