kulmasulkeet

Kulmasulkeet are elbow fittings used to change the direction of piping, typically creating a 90-degree bend. They are common in plumbing, heating, and fluid-handling systems and come in a range of sizes, materials, and connection types to suit different applications and standards.

Variants include 90-degree and 45-degree elbows. End connections may be threaded (NPT, BSP), compression, push-fit, or solvent-welded for plastics, while metal versions are often soldered or welded. Materials include brass, stainless steel, copper, galvanized steel, and various plastics such as PVC, CPVC, ABS, PEX, or multilayer composites.

Standards and installation considerations vary by region and material. Fittings typically have published pressure and temperature ratings. When assembling, match the connection type and sealant: use thread sealant or PTFE tape on threaded metal joints, appropriate O-rings on push-fit or gasketed joints, and ensure an unobstructed, full-bore flow to minimize pressure loss. Avoid overtightening threaded joints to prevent damage.

Applications and maintenance: Kulmasulkeet are widely used in domestic water distribution, heating circuits, and various industrial piping. They are subject to wear, corrosion, or leakage over time and should be inspected regularly. Replacement should use fittings of the correct material and rating, and installations should comply with local codes and standards.
