About

Established in 1984, Sing & San Construction Pte Ltd is a one-stop service provider specialising in comprehensive pipe installation solutions for water, gas, cable systems, process plants and pump systems, as well as civil engineering works.

Our expertise includes hot and under-pressure tapping on live pipelines, allowing for new connections without disrupting supply. For maintenance and repair work, our live insertion valves enable sectioning of pipelines without a full system shutdown—minimising downtime and operational impact.

We offer a full range of ductile iron pipes and fittings, including customised components to meet specific project requirements.

We are also the authorised distributor for Taisei Kiko’s earthquake-resistant systems, including Taiflex flexible joints and reinforcement fittings, which deliver reliable, seismic-resilient solutions for critical infrastructure.

 In addition, we offer Yano Stopper (live insertion valve) which provide reliable solutions for critical infrastructure maintenance without service interruption.

Piping Installation

We offer comprehensive pipe installation services for water, gas, and industrial systems, using top-quality materials and innovative methods to ensure safe, efficient, and long-lasting installations. Whether it’s new construction, system upgrades, or service diversions, our team is dedicated to delivering each project on time, with a strong commitment to safety, quality, and performance—tailored to meet your project's unique needs.

Live Insertion Valve Installation

Our live insertion valve enables precise isolation of pipelines during maintenance, repairs, or new connections—without the need for a full system shutdown. This innovative solution facilitates targeted work while maintaining operational flow, minimizing downtime, and enhancing system efficiency. Offering a flexible, cost-effective method for preserving pipeline integrity and performance, it’s ideal for water, gas and industrial applications.

Hot/Underpressure Tapping

Our under-pressure (hot) tapping service allows for new pipeline connections without interrupting the existing supply. This method enables seamless integration into live pipelines, reducing system downtime and ensures a continuous flow of water, gas, or other utilities. Perfect for urgent or critical connections, under-pressure tapping provides a safe and reliable solution for expanding infrastructure with minimal disruption.

Civil Engineering Works

Our civil engineering services encompass a wide range of projects, including roadworks, drainage systems, chamber construction, outfall structures, cycling paths and other civil works.  We specialise in designing and executing high-quality infrastructure solutions that meet both functional and regulatory requirements. From road construction to stormwater management, our expert team ensures the durability, safety, and efficiency of critical systems, delivering reliable results for both urban and industrial environments.

Tai-flex

Tai-flex is a ductile iron flexible expansion joint, that protects pipelines from seismic stresses, ground subsidence, and soft ground conditions.

Its unique design accommodates movement through expansion, contraction, bending, and rotation, making it ideal for reclaimed land and high-risk environments.

Widely recognised in Japan for its earthquake-resistant performance, Tai-flex ensures reliability in demanding applications.

Yano Stopper (Live Insertion Valve)

Yano Stopper (live insertion valve) enables safe connection, modification, or isolation of pressurised pipelines without shutting down the system.  Designed for water, gas, oil and chemical networks, it combines under pressure (hot) tapping and flow-isolation in one step.  Its pressure-resistant and leak-proof construction ensures fast deployment and reliable performance, that is ideal for maintenance and expansion or emergency repairs without service interruption.

Earthquake Resistant Reinforcement Fitting

Earthquake-resistant reinforcement fitting designed to enhance the seismic resilience of pipelines, providing a restraint capability of 3DkN (where D = diameter in mm). Compatible with A-Type, K-Type, and T-Type ductile cast iron pipe joints, this fitting strengthens existing infrastructure with minimal effort, offering the following benefits:

  • Supports joint movement within allowable angles after installation
  • Quick and easy installation—no special tools or equipment required
  • Fully compatible with retainer glands (A-Type and K-Type).

Flange Support

A compact and easy-to-use flange support, engineered to provide reliable restraint with a capability of 3DkN (D = diameter in mm). Designed for fast, tool-free installation, it secures easily by tightening a hex bolt—just like a standard flange bolt.

Key features include:

  • Easy installation on uneven or non-circular flanges (e.g., gate valve seats)
  • Compatibility with both vertical and horizontal pipe setups
  • Fits auxiliary and air valve flange jointsVersatile design: Can also be used as an emergency jig for temporary flange bolt replacement.

Mech-A-Poly Joint

Mech-A-Poly Joint is a mechanical coupling system specifically designed for joining Polyethylene (PE) pipes in a wide range of applications including:

  • Water supply systems
  • Gas distribution networks
  • Emergency pipe repairs

This joint provides a quick, tool-free installation solution without requiring fusion welding or specialised equipment.  It has excellent  watertightness ensuring high retaining performance with a corrosion resistant coating layer on its body.

Ductile Pipes and Fittings

Ductile iron pipes and fittings are renowned for their strength, durability and corrosion resistance, making them ideal for water, gas, sewage and industrial systems.  Offering high pressure resistance and flexibility, they are cost-effective and long-lasting.

Our range includes various pipe sizes, fittings, and custom components, providing reliable solutions for infrastructure projects that demand performance and longevity.

Ductile Split Tee

Ductile iron split tees are engineered for quick and efficient pipeline branching, providing reliable connections without the need for cutting the pipe and then inserting the new pipe section. Ideal for water, gas, and industrial applications, they offer excellent strength, corrosion resistance, and long-term durability. With a split design, these tees are easily installed on live pipelines, reducing downtime and ensuring minimal disruption to operations.

Custom Ductile Parts Casting

Our custom ductile iron casting services deliver high-quality, precision-engineered parts such as cable bearers or supports, valve keys, chamber covers, and more. Designed to meet the specific needs of your project, these parts provide superior strength, durability, and corrosion resistance. Whether it's a one-off or a large-scale production, our custom solutions ensure performance and longevity for a wide range of infrastructure and industrial applications.

Underpressure Tapping Machine

Underpressure tapping machines (also known as hot tapping machines) designed for precise drilling into live pipe systems. These machines allow you to create new connections without interrupting flow or leaking contents. They are ideal for water, gas, or utility applications minimising downtime and support continuous operation. We offer various sizes, and machines can be tailor-made to your specific requirements.

Power Cables

We supply a comprehensive range of power cables in various sizes and configurations, designed for use in high, medium and low voltage applications.  Our cables are manufactured to meet and exceed international standards such as IEC and BS, and local Singapore standards.  Built for reliability, safety and performance, they are ideal for diverse electrical infrastructure needs across industries.
