Product Information

Full details

This guide is for anyone needing to connect or repair pipes in adopted sewer and drainage systems, particularly those working on projects that require compliance with UK water company standards. The Flexseal SC200 Standard Coupling provides a reliable, airtight, and watertight seal, meeting the requirements of WIS 4-41-01. Note that while this coupling is versatile, it's designed specifically for connecting plain-ended pipes and is not suitable for all pipe configurations.

FAQs

What is the primary function of the shear band?

The shear band protects the joint against shear loads, helping to maintain pipe alignment and prevent displacement.

What standards does the Flexseal SC200 meet?

It complies with WIS 4-41-01, BS EN 295 Part 4, and EN681-1: 1995 requirements.

What tools are needed for installation?

A nut driver and a torque wrench are required.

What types of pipes can I connect with this coupling?

The SC200 is designed for plain-ended pipes, including vitrified clay pipes and fittings.

What is the maximum pressure the coupling can withstand?

The coupling can withstand an internal pressure of up to 2.5 bar.

Where can the SC200 be used?

It's suitable for various applications, including highways, utilities, infrastructure, and repair and maintenance projects.

How do I ensure a watertight seal?

Make sure the pipe ends are clean, the coupling is properly positioned, and the bolts are tightened to the correct torque.

Troubleshooting

Leakage at the joint

Check the torque of the bolts and tighten if necessary. Ensure the pipe ends are clean and properly aligned. If the issue persists, the coupling may need to be replaced.

Difficulty in tightening bolts

Make sure the bolt threads are clean and free of debris. Use a lubricant if necessary, but avoid over-tightening. If the issue persists, inspect the bolts and the coupling for any damage.

Pipe misalignment after installation

Ensure the pipes are correctly aligned before tightening the coupling. Check for any obstructions or debris that may be pushing the pipes out of alignment. If the problem persists, the coupling may not be the correct size.

Pros and Cons

Pros

  • Complies with stringent UK water company standards (WIS 4-41-01).
  • Provides a strong, shear-resistant connection to prevent pipe misalignment.
  • Quick and easy installation saves time and labor.
  • Creates a permanent airtight and watertight seal.
  • Suitable for a wide range of applications including highways and utilities.
  • Durable and reliable design ensures long-term performance.

Cons

  • Specific to plain-ended pipes; not compatible with all pipe types.
  • Requires a nut driver and torque wrench for proper installation.
  • May require professional installation for optimal performance.
  • Limited to specific pipe size ranges (175-200mm in this model).
  • The initial cost might be higher compared to some standard couplings.
  • Requires proper torque to ensure seal integrity.

Setup, Compatibility & Care

Setup

  1. Preparation: Ensure the pipe ends are clean, free of debris, and cut squarely.
  2. Placement: Slide the coupling over the pipe ends, centering the shear band over the joint.
  3. Tightening: Using a nut driver and torque wrench, tighten the bolts to the recommended torque specification (check manufacturer's guide for specifics). Ensure even tightening of all bolts.

Compatibility

The Flexseal SC200 is designed for plain-ended pipes and is compatible with vitrified clay pipes and fittings that meet BS EN 295 Part 4 & EN681-1: 1995 standards.

Care

  • Inspection: Regularly inspect the coupling for any signs of damage or leaks.
  • Maintenance: No specific maintenance is required after installation, provided the correct torque has been applied.
  • Replacement: If the coupling is damaged, replace it immediately to maintain system integrity.
