Supply & Demand

The main body of the valve is made of PPR material, and both ends have heat-melt socket connections that are compatible with PPR water pipes; the internal valve core and valve stem adopt a brass sealing structure, with a handwheel switch on the top, and are formed by one-piece injection molding. There are standard specifications such as 20/25/32 diameters.

The entire product is made through a single injection molding process of food-grade PPR. There are two heat-melt socket connections of the same specification, forming a 90-degree right angle, without metal threads. There is also a 45-degree elbow of the same series.

通体纯 PPR 原料一体注塑成型，三个端口规格一致，全部为热熔承插口，无金属螺纹。

One end is a PPR plastic socket (heat fusion butt joint PPR pipe), with a 90° angle; the other end has an embedded thickened brass internal thread, which is injection-molded as one piece; the mainstream socket specifications for home decoration are 1/2" (4/4) and 3/4" (6/4).

The two connectors are pure PPR interfaces (heat fusion butt PPR pipes), with internal brass threads in the middle branch, and are formed by one-piece injection molding. There are also three-way connectors with equal diameters, and the commonly used sizes for home decoration are 4-inch and 6-inch internal threads.

PPR direct connection, also known as PPR direct, both ends are PPR plastic sockets, using hot melt welding. It is used for straight connection between two sections of PPR pipes of the same diameter. It is the most basic pipe fitting for water supply systems.

The PPR external thread connector has one end as a PPR plastic socket (for hot-melt connection of PPR pipes), and the other end is a metal external thread. It is specifically designed to achieve the connection between PPR plastic pipes and metal fittings with internal threads or metal hoses, and is a necessary conversion pipe fitting for waterway installation.

Leveraging our expertise and in-house manufacturing capabilities, we excel in providing tailor-made and turnkey solutions for inspecting a wide range of products, including welded or seamless tubes, wires, bars, strips, rails, and custom parts. Our systems are designed to be installed in-line or off- line to perform surface and full body defect detection, highly accurate dimensional measurements, material sorting, and process analysis (such as sigma phase, heat treatment, conductivity, etc.).

Strap Material: PET strap (plastic steel strap) and PP strap (plastic strap) Strap Size: 16.0 – 19.0 x 0.65 – 1.35 mm Tension Strength: 500 – 4000 N (adjustable) Sealing Type: Friction heating Battery: 18VDC / 5.0 Ah Weight: 4.3 kg / 9.6 lbs The P329S PET strap electric strapping machine comes with a new LCD touchscreen for easier use while retaining the P329 model’s original features, famous for its "high durability." Its angled base design makes it easier to remove the strap from the machine, preventing the strap from breaking due to excessive tension. The control panel is in both Chinese and English, and the tension strength (in Newtons) can be adjusted. The P329S electric strapping machine features a high-efficiency brushless motor paired with a large-capacity 5.0Ah new lithium-ion battery,

Strap material: PET strap (plastic steel strap) and PP strap (plastic strap) Strap size: 12.0 – 16.0 x 0.40 – 1.05 mm Tension force: 250 – 2,600 N (adjustable) Sealing type: Friction heat Battery: 18VDC / 5.0 Ah Weight: 4.3 kg / 9.6 lbs The P328 battery-powered plastic steel strapping machine, based on the previous P326 model, uses a brushless motor, smart motor temperature control, and a super-large 5.0Ah lithium battery. It’s currently one of the battery-powered strapping machines on the market with the longest battery life, allowing multiple straps to be tightened on a single full charge. The P328 runs on battery power, making it easy to move around and suitable for large working areas. It can be used for both light and heavy packaging, and works with both smooth and
