The grooved piping method is a modern, flame-free, and highly dependable system for joining pipes. It serves as an efficient, reliable, and cost-effective alternative to traditional welding, flanging, or threading. As a pioneering manufacturer with a rich history dating back to 1982, we are committed to building a safer world by delivering premium pipe fittings to every project. This commitment has earned us the trust of a global customer base, with distribution in over 100 countries and a remarkable reorder rate exceeding 90%.
The brilliance of the grooved pipe connector lies in its straightforward and efficient assembly, creating a secure joint in a fraction of the time required by other methods.
1.Pipe Preparation: A groove is precisely formed on the pipe end using a roll-grooving machine. The pipe ends are checked to ensure they are clean and free of any indentations or projections that could interfere with a proper seal.
2.Gasket Installation: A resilient, pressure-responsive rubber gasket is lubricated and positioned over the two pipe ends. This component is crucial for creating the leak-proof seal.
3.Housing Assembly: Two housing segments are placed over the gasket. The keys of the housing engage directly with the grooves on both pipes.
4.Securing the Connection: Bolts and nuts are inserted and tightened to secure the housing segments together. This action firmly clamps the pipe ends, locks them in place, and creates a unified, permanent, and leak-tight joint.
Every grooved coupling consists of three essential components working in unison to provide unparalleled performance:
> The Housing: The outer casing is manufactured from high-strength Ductile Iron (ASTM A536, Grade 65-45-12), designed to withstand the toughest conditions. Its primary function is to encase the gasket and securely grip the pipe grooves.
> The Gasket: This is the heart of the seal. Our gaskets are available in various materials to suit different services, including EPDM, Nitrile, and Silicone to suit different applications and temperature ranges (e.g., EPDM for -30°C to 130°C). The unique C-shaped profile creates a triple-seal that is enhanced as internal line pressure increases.
> The Bolts & Nuts: High-tensile, heat-treated bolts and nuts are used to secure the housing segments. They are typically treated with an anti-corrosion coating, such as hot-dip galvanizing, to ensure long-term reliability and easy maintenance.
> Unmatched Reliability and Safety: Our "Safer, No Leak!" commitment is proven by an industry-leading 99.96% product qualification rate and a return rate of just 1 in 440,000. Every single fitting is rigorously tested for airtight and hermetic performance to prevent leaks.
> Speed and Cost-Effectiveness: The grooved method allows for significantly faster and easier installation compared to welding, reducing labor hours and overall project costs.
> Proven Durability: Manufactured from superior ductile iron, our fittings are built to last and withstand demanding conditions. Various surface treatments, including epoxy and hot-dip galvanizing, provide superior corrosion resistance.
> Design Flexibility: The system allows for both rigid couplings (Fig. XGQT01) for a firm joint and flexible couplings (Fig. XGQT02) to accommodate vibration, thermal expansion, and contraction without compromising seal integrity.
> Easy Maintenance: The system can be easily disassembled for maintenance or modification by simply removing the bolts and nuts, saving valuable downtime and simplifying system access.
> Material: High-Tensile Ductile Iron conforming to ASTM A536, GRADE 65-45-12.
> Available Sizes: A comprehensive range from 1" to 24".
> Pressure Ratings: Designed for working pressures up to 363 PSI (2.5MPa) and subjected to compressive strength tests up to 4 times the rated working pressure.
> Surface Finishes: Options include Epoxy Painted, Hot-Dip Galvanized, Electroplated, and Black finishes for superior corrosion protection.
> Certifications & Approvals: Our products are globally recognized and certified by leading authorities, including UL, FM, VDS, CE, ISO, NSF, and CCC, ensuring our products meet the highest international standards for safety and quality.
> Gasket Specifications: A variety of gasket materials are available for different services, such as EPDM for a temperature range of -30°C to 130°C.
