Selecting and Using PVC Pipes, Fittings, and Valves for Various Systems
Choose PVC pipes with proven resistance to corrosion and chemical influences. The manufacturer offers products with precise diameter and wall thickness parameters, guaranteeing durability and tightness. Proper selection of fittings will facilitate installation and reduce the risk of leaks, even under high pressure.

pvc fittings provide a reliable connection between various pipeline components. When purchasing, pay attention to the diameters and connection type—socket, coupling, or adhesive. The manufacturer adheres to quality standards, which helps avoid installation and operation issues.
Shut-off valves must meet the specific system requirements and flow rate requirements. Preference should be given to products with a convenient control mechanism and a service life designed for long-term operation without maintenance. The manufacturer offers components that easily integrate into PVC piping and ensure reliable flow control.
Selecting PVC Pipes: Types, Sizes, and Specifications for Specific Applications
The manufacturer Aquaplast recommends selecting PVC pipes based on the operating pressure and temperature of the medium. For cold water systems, PN10–PN16 pipes with diameters from 20 to 110 mm are ideal. They withstand pressures up to 16 bar and temperatures up to +45°C.
For sewer and drainage systems, pipes with a smooth inner surface and diameters from 110 to 315 mm are suitable. Their weight and wall thickness effectively handle the loads of underground installations and dynamic impacts. Note the SN marking, which indicates the pipe’s rigidity. For heavy-duty conditions, choose SN8 or higher.
When installing systems with chemically aggressive environments, you should choose pipes with improved resistance to aggressors – for example, modified PVC or reinforced types. The manufacturing company offers options with increased resistance to solvents and acids, which affects the choice of material and wall thickness.
Pipe sizes are selected based on throughput: diameters of 32–50 mm are suitable for domestic needs, and 110 mm or more for industrial needs. It is also important to consider the parameters of the connections: it is optimal to use compression or socket fittings with appropriate seals to ensure tightness and ease of installation.
Technical characteristics influencing the choice: coefficient of linear expansion, tensile strength, ultraviolet resistance and frost resistance. For outdoor applications, select pipes with a UV protective layer or coating that prevents damage from sun exposure.
The correct choice of PVC pipes is achieved by a combination of parameters of pressure, diameter, chemical resistance and operating conditions. This company is ready to offer optimal solutions, taking into account the specifics of the task and regulatory requirements.
Installation and sealing of PVC fittings: step-by-step instructions and common mistakes
Begin installation by preparing pipes and fittings: clean the ends of dust, dirt and moisture, while the cut should be smooth and without burrs. To do this, use a specialized knife and sandpaper. The manufacturing company recommends measuring the pipe ends using a ruler to ensure the exact length of the connection.
Step-by-step instructions for installing PVC fittings
- Apply special PVC glue to the surface of the pipe and the inside of the fitting in an even layer. Do this quickly to avoid the glue drying out.
- Insert the pipe into the fitting, checking that the connection is tight without distortion.
- Rotate the pipe inside the fitting 10-15 degrees to distribute the adhesive evenly.
- Clamp the connection for 30 seconds, keeping the elements stationary.
- Wipe off excess adhesive with a dry cloth and allow to dry according to the manufacturer’s instructions – usually 15 to 30 minutes to set and at least 2 hours before loading.
Typical installation errors and their consequences
A common mistake is applying glue to poorly cleaned or damp surfaces, which reduces adhesion and leads to leaks. Insufficient rotation of the pipe during connection causes local accumulation of glue and poor sealing. Too short a time for fixing the structure and early operation before the glue has completely dried often causes depressurization of the unit. Neglecting the evenness of the cuts reduces the contact area and the strength of the connection.
This company advises using glue and solvents only from trusted manufacturers and strictly following temperature recommendations during installation. Thus, you guarantee the durability and reliability of the system without leaks.
Features of operation and maintenance of shut-off valves in plastic pipelines
Maintenance recommendations
Clean the surface of fittings and mechanisms from contaminants that may interfere with the smooth movement of the valves. When servicing, avoid using abrasive or aggressive cleaning agents that could damage the plastic or seals. Once every 6 months, check the tightness of the fasteners and, if necessary, tighten them to prevent deformation of the parts.
Operating conditions and failure prevention
Monitor the temperature and pressure in the system – exceeding the standard values will lead to deformation of the plastic components and failure of the fittings. When installing, consider the direction of flow and ensure easy access to shut-off valves for timely maintenance. In the cold season, use insulation to prevent water freezing and subsequent destruction of pipeline elements and fittings.
