Product Introduction

Products Description

Large diameter LSAW steel pipe are produced by molding hot-rolled coil plate steel into a cylinder and joining the ends together by welding in a straight line. This creates a pipe welded longitudinally. These pipes are mainly used for long-distance transmission pipelines for oil, gas, liquid coal, hydrocarbon, etc. There are two types of LSAW pipes: single longitudinal seam and double seam. LSAW pipes compete with seamless and ERW pipes in the size range between 16 and 24 inches. In the oil and gas industry, large-diameter LSAW pipes are used to transport hydrocarbons over long distances efficiently.

Large diameter LSAW steel pipe steel pipe is formed by rolling and welding a steel strip in a helix or spiral direction, making the weld seam in a spiral line. The spiral welded process makes it possible to create large diameter options. Spiral steel pipes are mainly used for low-pressure fluid transmissions such as pipelines on offshore platforms, petrochemical industry plants or shipyards as well as civil construction and pile driving.

Products Advantages

In the long-distance pipeline construction, with steel lines account for a large proportion, under normal circumstances, 35% to 40% of line pipe investments accounted for total project investment. How to choose a reasonable price, excellent performance of the pipe is particularly important, a reasonable choice to save the pipe construction investment, to facilitate the construction and safe operation of the pipeline system has a very important impact. LSAW steel pipe advantage make it can be widely used for its unique long-distance oil and gas pipelines.

Advantages of LSAW steel pipe are:

● Without the unwind process, the base material indentation, scratch less.

● The wrong side, slotted, and other easy-to-diameter perimeter control, excellent welding quality.

● The elimination of flaring basically does not exist residual stress after stress.

● Because it is a straight line weld, the weld is short, little risk of defects.

● After expanding, pipe geometry accuracy is improved greatly facilitate the on-site welding.

● For a straight seam, less impact on the quality of anti-corrosion coating materials.

Quality Control Measures

100% radiographic testing of welds

Ultrasonic testing for laminations

Charpy V-notch testing (for low temp applications)

Hardness testing across weld zone

Coating adhesion tests (for coated pipes)
