What are the precautions for installing grooved pipe fittings?

Currently, the trend of installing grooved pipe fittings has gained significant popularity due to their practical and convenient characteristics. If you're considering their installation, it's essential to understand the precautions that should be taken to ensure a successful setup. Here’s a detailed overview:

1. Quality Control of Pipe Cutting Process

Ensuring that the end face of the cut pipe is perpendicular to the steel pipe's axis is crucial. Any burrs present can significantly impact the sealing effect of the rubber ring. Therefore, quality management during the pipe-cutting process should not be neglected.

Utilize grinding wheel cutters or pipe cutters for cutting steel pipes, while avoiding oxyacetylene methods. It's important to secure the pipe adequately to prevent cross-section dislocation and excessive burrs during the cutting process. After cutting, all burrs should be removed using sandpaper, files, or grinders.

2. Setting Support (Hanging) Frames

Unlike traditional connections such as welding or flanges, grooved connection systems leave a gap between the groove and the pipe, which can lead to axial displacement during pressure tests or temperature changes. Improper support and hanging frame installations can lead to leaks at these joints. Ensuring an adequate number of supports and strategically positioning them is essential to prevent leakage and deformation in pipelines.

3. Rubber Ring Installation

The rubber ring serves as a vital seal for grooved pipe fittings. When tightening the bolts on both sides of the groove and pipe fittings, it's crucial to do so alternately. Keep an eye out for any wrinkles in the rubber sealing ring. If any such wrinkling is noticed, it’s best to replace the ring with a new one to maintain a reliable seal.

4. Quality Control of the Groove Rolling Process

Proper roll grooving is essential as it is a critical process for creating the grooves. Rushing through this stage might damage the galvanized layer of the pipeline. Moreover, rolling grooves that are either too deep or too shallow can adversely affect the quality of the pipeline interface.

Specifically, if the groove depth is excessive, it may deform the pipe end and deteriorate the installation quality. Conversely, grooves that are too shallow can lead to improper fitting of the rubber ring, risking leakage. To prevent these issues, procedures must be meticulously followed, allowing for proper adjustments and utilizing limit devices to maintain groove depth within acceptable ranges.

In summary, the above precautions are vital for installing grooved pipe fittings properly. Observing these guidelines will enhance the reliability and performance of the installation.
