Avoid inferior parts and extend system life by 50 bliadhnaichean

Heating Pipe Fittings anns Plumaireachd

Pìoban PPR (polypropylene copolymer air thuaiream) : The most mainstream choice at present. High heat resistance (Suas gu 110 ° C for a short time at 95 °C), strì an aghaidh cuideam, strì an aghaidh creimeadh, no interface hazard in hot-melt connection, insulation math, moderate price, beatha seirbheis fhada (theoretical value of 50 bliadhnaichean). Recommended for use.

Aluminum-plastic composite pipe: Pressure-resistant, heat-resistant, good oxygen permeability resistance, no rebound when bent, easy to connect (clamping or sliding type). But the cost of the joints is slightly higher and the installation requirements are strict. Recommended for use (especially in exposed installations or where bending is required).

PB pipe (polybutylene pipe) : Excellent performance (better than PPR in flexibility, heat and pressure resistance, strì an aghaidh buaidh, and insulation), but expensive, with a lower market share.

Galvanized steel pipe: Traditional material, àrd neart, high heat resistance. But not recommended for newly installed systems: prone to rust, corrosion and scaling (reducing flow, polluting the system), stàladh iom-fhillte (requiring threading or welding), poor insulation, relatively short lifespan.

Stainless steel: Extremely strong, resistant creimeadh, hygienic, extremely long service life. But they are expensive, have special connections (crimping, welding), and are mainly used in high-end or special demand situations.

Function: A channel for transporting hot water or steam, the main trunk and branch of the system.

Bhalbhaichean (for flow control, opening and closing, regulation, sàbhailteachd)

1. Stop valves/gate valves

Valve body/cover: pràis (mainstream, good corrosion resistance), cast iron (cheap but prone to rust, not recommended for home use), Stàilinn nach meirg (high-end, excellent corrosion resistance).

Valve stem: Stainless steel (rust-resistant).

Sealing material: High-quality rubber or polytetrafluoroethylene (PTFE).

Function: Primarily used to cut off or connect the medium (water/steam) in the pipeline. The regulating performance of the stop valve is slightly better than that of the gate valve, but the resistance is slightly greater; A gate valve has less resistance when fully open. Stop valves are commonly used in heating systems.

2. Ball comhla

Valve body/Cover: Bras (most commonly used), Stàilinn nach meirg (high-end, resistant creimeadh).

Ball: chrome-plated brass, Stàilinn nach meirg.

Valve stem: Stainless steel.

Seal: PTFE.

Function: Quick opening and closing by rotating a 90-degree sphere. Easy to operate, quick on/off, low resistance, good sealing. It is perfect as a switch control valve for radiators or pipe sections.

Thermostatic valve (thermostatic valve)

Valve body: pràis (mainstream), Stàilinn nach meirg.

Valve core: Quality engineering plastic, Stàilinn nach meirg.

Temperature sensing element: paraffin or special liquid.

Function: Installed at the water inlet of the radiator, automatically regulates the flow of water into the radiator to precisely control the room temperature. After the user sets the target temperature, the temperature-sensing element inside the valve head automatically expands/contracts according to room temperature, driving the valve core to open and close. A key accessory for energy efficiency and comfort.

Balance valve (static/dynamic)

Valve body: Bras, cast iron (large main pipe), Stàilinn nach meirg.

Valve core/measuring element: Stàilinn nach meirg, engineering plastic.

Function: Regulate the hydraulic balance of the system, ensure that each loop or each radiator gets the designed flow, and solve the problem of near hot and far cold. The static balance valve requires manual measurement and debugging; Dynamic balance valves (self-operated differential pressure/flow control valves) can automatically adapt to changes in system pressure to maintain the set flow.

Safety valve/relief valve

Valve body: Bras, Stàilinn nach meirg.

Spring: Stainless steel.

Function: Install in critical positions such as the highest point of a boiler or system. When the system pressure exceeds the set value, it automatically opens for pressure relief to prevent overpressure from causing equipment damage or safety accidents. It is an essential safety device.

Automatic exhaust valve

Valve body: Bras (mainstream), Stàilinn nach meirg, plastaig (low-end, use with caution).

Float/Seal: Stàilinn nach meirg, premium rubber/plastic.

Function: Install at the highest point of the system or where air is likely to accumulate. Automatically expel the accumulated air in the pipes to prevent air blockage from affecting circulation and heat dissipation. Ensure the system is functioning properly.

This comprehensive guide covers the most common fittings in a heating piping system. Ann an cleachdadh practaigeach, select and purchase under the guidance of a professional based on your specific system type (central heating/independent heating/underfloor heating/radiator), design drawings, budget, and local market availability.
