borular

Borular are cylindrical hollow members used to convey liquids, gases, slurries, or granular materials from one location to another. The word boru in Turkish is pipe, and borular is the plural. They are manufactured in a wide range of materials and sizes to suit different pressures, temperatures, and chemical compatibilities.

Common materials include metal pipes such as steel, stainless steel, ductile iron, and copper; plastic pipes such as polyvinyl chloride (PVC), chlorinated PVC (CPVC), polyethylene (PE), and cross-linked polyethylene (PEX); as well as composite and reinforced polymer pipes.

Manufacturing methods vary by material. Metal pipes are produced as seamless or welded tubes, often with surface coatings to resist corrosion. Plastic pipes are typically extruded into continuous lengths or coils and joined by solvent welds, heat fusion, or mechanical fittings. Drainage and pressure pipes may be corrugated for flexibility.

Borular are used in municipal and industrial systems for water supply, wastewater, natural gas, oil and chemical transport, heating and cooling networks, and agricultural irrigation. They range from small bore tubes for domestic plumbing to large-diameter pipes for underground conduits or high-pressure lines.

Sizing and standards use nominal dimensions and pressure ratings. In many regions, nominal pipe size (NPS) or DN (diameter nominal) is used. Joints include threaded, flanged, grooved, welded, or solvent‑cement connections, with specific fittings and gaskets for each system.

Installation and maintenance emphasize proper material selection, corrosion protection (such as coatings or cathodic protection for steel), insulation to prevent energy loss, and leak detection. Regular inspection helps detect wear, erosion, or joint failures.

History: Ancient civilizations constructed primitive pipes from clay, stone, or copper. Industrialization brought cast iron and steel pipes, followed by widespread use of plastic pipes from the mid-20th century, which expanded options for cost, corrosion resistance, and installation speed.
