Heating Pipe Fittings ໃນ ທໍ່ນ້ຳ

ທໍ່ PPR (polypropylene copolymer ແບບສຸ່ມ) : The most mainstream choice at present. High heat resistance (ເຖິງ 110 ° C for a short time at 95 °C), ຄວາມຕ້ານທານຄວາມກົດດັນ, ການຕໍ່ຕ້ານ corrosion, no interface hazard in hot-melt connection, good insulation, moderate price, ຊີວິດການບໍລິການຍາວ (theoretical value of 50 ປີ). 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, ຄວາມຕ້ານທານຜົນກະທົບ, and insulation), but expensive, with a lower market share.

Galvanized steel pipe: Traditional material, ຄວາມ​ເຂັ້ມ​ແຂງ​ສູງ​, high heat resistance. But not recommended for newly installed systems: prone to rust, corrosion and scaling (reducing flow, polluting the system), ການຕິດຕັ້ງທີ່ສັບສົນ (requiring threading or welding), poor insulation, relatively short lifespan.

Stainless steel: Extremely strong, ທົນທານຕໍ່ການກັດກ່ອນ, ສຸຂະອະນາໄມ, 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.

ວາວ (for flow control, opening and closing, regulation, ຄວາມປອດໄພ)

1. Stop valves/gate valves

Valve body/cover: ທອງເຫຼືອງ (mainstream, good corrosion resistance), cast iron (cheap but prone to rust, not recommended for home use), ສະແຕນເລດ (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 valve

Valve body/Cover: ທອງເຫຼືອງ (ໃຊ້ທົ່ວໄປທີ່ສຸດ), ສະແຕນເລດ (high-end, ທົນທານຕໍ່ການກັດກ່ອນ).

Ball: chrome-plated brass, ສະແຕນເລດ.

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, ການຜະນຶກທີ່ດີ. It is perfect as a switch control valve for radiators or pipe sections.

Thermostatic valve (thermostatic valve)

Valve body: ທອງເຫຼືອງ (mainstream), ສະແຕນເລດ.

Valve core: Quality engineering plastic, ສະແຕນເລດ.

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: ທອງເຫຼືອງ, cast iron (large main pipe), ສະແຕນເລດ.

Valve core/measuring element: ສະແຕນເລດ, 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: ທອງເຫຼືອງ, ສະແຕນເລດ.

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: ທອງເຫຼືອງ (mainstream), ສະແຕນເລດ, ພາດສະຕິກ (low-end, use with caution).

Float/Seal: ສະແຕນເລດ, 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. ໃນ​ການ​ນໍາ​ໃຊ້​ພາກ​ປະ​ຕິ​ບັດ​, 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.
