SCH8O/DIN UPVC/CPVC Blind Flange

UPVC/CPVC blind flanges are high-performance pipe fittings widely used in industries such as chemicals, construction, and water treatment. They offer corrosion and high-temperature resistance, ensuring reliability in harsh environments.

Blind flanges are used to seal the ends of pipelines, preventing liquid or gas leakage and facilitating system maintenance and repair. Their lightweight design simplifies installation and handling, while their strong compatibility with other standard pipe fittings meets diverse project requirements.

The smooth surface of UPVC/CPVC blind flanges reduces fluid resistance, contributing to overall system efficiency.

SCH80/DIN UPVC/CPVC Blind Flange - Durable Sealing for Industrial Piping Systems

  • Material Composition: Manufactured from SCH80 UPVC (Unplasticized Polyvinyl Chloride) and CPVC (Chlorinated Polyvinyl Chloride), ensuring resistance to a wide range of chemical media. This makes the blind flange suitable for applications where **chemical resistance** is paramount.
  • Structural Integrity: Designed according to **DIN standards** to provide a robust and secure seal at the end of a pipeline. Its solid, disc-like structure is engineered to withstand pressures without leakage, which is crucial for **pipe system maintenance** and shutdown applications.
  • Ease of Installation: Features a bolt pattern that aligns with standard pipe fittings, allowing for straightforward **UPVC/CPVC blind flange installation** and removal. This design simplifies pipeline modification and repair procedures, reducing downtime in industrial settings.

This blind flange is manufactured in compliance with **ASTM D1784** for material and **DIN 8063** for dimensions, ensuring compatibility and consistent performance. The product is designed to provide a secure and non-corrosive seal for isolating sections of piping systems. Its non-metallic construction prevents galvanic corrosion, a common issue in mixed-material systems, making it a reliable component for **industrial fluid handling** and **water treatment** applications.

FAQ

1. What are the key differences between a UPVC and CPVC blind flange, and how do I choose the correct one for my application?

The primary distinction lies in their **temperature resistance**. A **UPVC blind flange** is suitable for applications with a maximum operating temperature of up to 60°C, while a **CPVC blind flange** can handle media with temperatures up to 95°C. The choice depends entirely on the specific fluid temperature and operational environment of your system. For instance, processes involving hot corrosive liquids necessitate the higher thermal rating of CPVC. To ensure you select the optimal flange, please consult our technical specifications against your operational parameters. Our application engineers can provide a free consultation to analyze your specific requirements.

2. How does the pressure rating of an SCH80 non-metallic blind flange compare to its metallic counterpart, and can it handle industrial pressures?

While metallic flanges generally have higher pressure ratings, an **SCH80 non-metallic blind flange** is engineered to meet the pressure demands of many industrial fluid systems, typically up to 1.0 MPa (150 PSI) at standard temperatures. The pressure rating is a function of both material properties and temperature; as temperature increases, the pressure rating decreases. It is important to check the pressure-temperature derating charts for the specific material (UPVC or CPVC) and operational conditions. Our blind flanges are rigorously tested to ensure they maintain structural integrity and a leak-proof seal within their specified limits, providing a reliable, corrosion-free solution for your **high-pressure UPVC/CPVC piping needs**.

Installation specifications and sealing precautions for UPVC/CPVC blind flanges

UPVC (unplasticized polyvinyl chloride) and CPVC (chlorinated polyvinyl chloride) blind flanges are widely used in many industries due to their excellent corrosion resistance, lightweight and high cost performance, including safe drinking water, metallurgy, photovoltaics, nuclear power, electronic semiconductors, medicine, industrial water treatment, industrial wastewater and other fields. To ensure its long-term stable operation, installation and sealing are crucial. The following are key specifications and precautions:

1. Installation specifications
Flange alignment and tightening
Before installation, check whether the flange surface is flat to avoid stress concentration due to misalignment.
Gradually tighten the bolts in a diagonal order (it is recommended to use stainless steel or corrosion-resistant bolts) to avoid uneven force on one side and affect the sealing.

Gasket selection
Select suitable gaskets (such as EPDM, PTFE or rubber gaskets) according to different media, for example:
Safe drinking water/pharmaceutical industry: must comply with FDA or sanitary standards (such as EPDM).
Industrial wastewater/metallurgical industry: PTFE gaskets that are resistant to acid and alkali corrosion are more suitable.

Temperature and pressure adaptation
UPVC temperature range (0°C~60°C), CPVC can withstand higher temperatures (-40°C~93°C), and materials must be strictly distinguished in scenarios such as photovoltaics (cooling systems) or nuclear power (auxiliary pipelines).
Avoid overpressure use, especially in high-purity water systems in the electronic semiconductor industry, where pressure fluctuations may cause flange deformation.

Support and shockproof
Long pipeline systems (such as industrial water treatment plants) require additional brackets to reduce the vibration load of blind flanges.

2. Sealing precautions
Surface cleaning
Thoroughly clean the flange sealing surface and the inner wall of the pipeline before installation to prevent particulate matter (such as metal debris in the metallurgical industry) from affecting the sealing effect.

Avoid over-tightening
UPVC/CPVC materials have low hardness. Over-tightening of bolts may cause flange cracking, especially in low-temperature environments (such as photovoltaic plant cooling systems).

Media compatibility check
The pharmaceutical/electronic semiconductor industry needs to ensure that the blind flange material does not release harmful substances (such as plasticizers).
In industrial wastewater treatment, it is necessary to resist chemical corrosion such as chlorine and sulfide.

Regular maintenance
In nuclear power or highly dangerous fluid systems, it is recommended to check the flange sealing status regularly to prevent sudden leakage.

3. Key points of industry application
Safe drinking water/pharmaceuticals: give priority to sanitary CPVC flanges to avoid biological contamination.
Photovoltaics/electronic semiconductors: pay attention to the aging effect of thermal cycles on sealing gaskets.
Metallurgy/industrial wastewater: strengthen chemical corrosion resistance design, such as thickened flanges or anti-corrosion coatings.
