Blind Flange Types - HEBEI JIUYUAN | Material & Standards

Introduction

Blind flanges are critical components in industrial piping systems, designed to block off pipelines, valves, or pressure vessels. These solid disks ensure secure sealing and compatibility with international standards, making them indispensable in sectors like oil & gas, petrochemicals, and power generation. This article delves into the Blind Flange product, its technical specifications, applications, and the expertise of its manufacturer, HEBEI JIUYUAN PIPELINE MANUFACTURING CO.,LTD.

Product Overview

Blind flanges are engineered to provide a robust, leak-proof seal in piping systems. Unlike traditional flanges, they lack a central hole, making them ideal for temporary or permanent closures. The Blind Flange offered by HEBEI JIUYUAN PIPELINE MANUFACTURING CO.,LTD is available in a wide range of pressure ratings (PN6 - PN40/Class150 - Class2500) and sizes (DN10 - DN2000/½In - 24In). This versatility ensures compatibility with diverse industrial requirements.

Installation Guide

Proper installation of a Blind Flange ensures a secure, leak-proof connection. Follow these steps:

  1. Preparation: Clean flange faces and gaskets to remove debris.
  2. Gasket Placement: Use a compatible gasket for the system's fluid and pressure requirements.
  3. Bolt Alignment: Align bolt holes and insert bolts, ensuring correct grade and number as per flange ratings.
  4. Tightening: Tighten bolts in a crisscross pattern with a torque wrench to prevent warping and ensure even pressure.
  5. Testing: Conduct pressure tests to verify the seal's integrity.

Always follow safety protocols, especially in pressurized or hazardous environments.
