Category: LSAW Pipe

LSAW Steel Pipe, or Longitudinal Submerged Arc-Welding Pipe, is manufactured using steel plates as the raw material. The plates are shaped using a molding machine and then undergo double-sided submerged arc welding. This process imparts the LSAW steel pipe with superior ductility, weld toughness, uniformity, plasticity, and excellent sealing properties.

LSAW Steel Pipe is subdivided into UOE, RBE, and JCOE steel pipe according to its different forming methods. Longitudinal high-frequency welded steel pipe has the characteristics of a relatively simple process and fast continuous production, and has wide use in civil construction, petrochemical, light industry, and other sectors. Mostly used to transport low-pressure fluids or made into various engineering components and light industrial products.

Diameter range and performance of LSAW pipe

The diameter range of LSAW pipes is broader than that of ERW pipes, typically spanning from 16 inches to 60 inches (406 mm to 1500 mm). They demonstrate excellent performance in terms of high-pressure resistance and low-temperature corrosion resistance.

Features:

Large diameter steel pipes
Thick walls
High-Pressure resistance

LSAW Steel Pipe Applications

1. LSAW pipes are extensively used in oil and gas pipelines, particularly where large-diameter and thick-walled pipes with high strength are required for long-distance transportation.
2. They are also utilized in construction projects that demand robust strength, such as water treatment facilities, thermal industries, and bridge construction.
3. According to API specifications, LSAW steel pipes are specifically designed for large-scale oil and gas transportation, especially in scenarios where pipelines traverse urban areas, cities, and seas.

Tests

-Chemical Component Analysis
