UNIASEN products

Spiral submerged arc welded (SSAW) pipes has spiral welding joints and the pipes are welded and formed at the same time. The strip steel with the same speci?cation can produce SSAW pipes with various diameters.

Longitudinally Submerged Arc Welding (LSAW) pipes use single plate steel as raw material, applied double-sided submerged arc welding. The ?nished products have larger speci?cations and the welding joints have excellent ductility, plasticity and good sealing.

Hollow structural section (HSS) is a type of metal pro?le with a hollow tubular cross section, including Square Pipes and Rectangular Pipes. Hollow Sections are commonly used in welded steel frames where members experience loading in multiple directions.

UNIASEN offers line pipe in a wide range of size, length, diameters and steel grade. Products can be used to transport oil, gas, petroleum, and water. Our line pipes are strictly made in accordance with the product specification (API 5L) set by the that were developed by the American Petroleum Institute. UNIASEN offers ERW line pipe in a wide range of size, length, diameters and steel grade. Products can be used to transport oil, gas, petroleum, and water. Our line pipes are strictly made in accordance with the product specification (API 5L) set by the that were developed by the American Petroleum Institute.

Casing and tubing strings are the main parts of the well construction. All wells drilled for the purpose of oil or gas production (or injecting materials into underground formations) must be cased with material with sufficient strength and functionality.Oil country tubular goods (OCTG) is a family of seamless rolled products consisting of drill pipe, casing and tubing subjected to loading conditions according to their specific application.

Slotted liner is actually a kind of sand control screen, chiefly used as the water and oil reservation layer for sand control. Its major function is to prevent rock pieces dropping into the water or the oil well. This type of slotted product is commonly used in sand control devices, especially useful for horizontal wells.

Piling pipe is a structural building material used to support and stabilize a building`s foundation. When the soil below a building is loosely packed, it may not offer enough strength to keep the building stable over time. A pipe piling can be used to distribute the weight of the building deeper into the earth, where the soil is often more tightly packed. Pipe piles are also used to support exceptionally large or heavy buildings, where even standard soil cannot offer adequate support. Finally, a pipe piling may be required when the land area is too small to accomodate spread footers or foundations, forcing buildings to dig deeper to achieve sufficient ground stability.
