Grooved (clamp) cross
The grooved clamp cross is a specialized pipe fitting for welding-free, rapid assembly, and four-way diversion and merging. It relies on pipe grooves, dedicated clamps, and sealing rubber rings for mechanical locking and sealing, requiring no hot work welding and no threading or tapping, greatly simplifying the construction process of pipeline diversion nodes. It is mainly used for four-way medium distribution operations in water supply and drainage, fire sprinkler systems, fire hydrant systems, HVAC hot and cold water circulation, municipal water supply, and factory circulating water pipe networks, enabling four-way even distribution from the main pipe, reducing-diameter diversion, and precise water extraction and diversion from local branches. The integrated cross is suitable for prefabricated whole-section assembly of pipelines, while the mechanical tapping cross can directly connect branches to the side of the main pipe opening without cutting off the main pipe, greatly reducing renovation construction costs. The product features shock absorption, noise reduction, and slight displacement compensation functions, which can effectively mitigate

Detailed Introduction
Grooved (clamp) cross, also known as clamp cross, is a key pipe fitting in prefabricated piping systems. The product ports are prefabricated with standard annular grooves, which, together with dedicated clamps and rubber sealing rings, achieve rapid locking without the need for welding or thread machining, simplifying the construction of pipeline branch nodes. It mainly complies with standards such as GB/T36019-2018 and GB5135.11, with a nominal diameter range of DN25-DN300 and a conventional working pressure of 1.6MPa. The main body material is ductile iron QT450-10, and 304/316L stainless steel can also be customized. The products are divided into integral type and open-hole mechanical cross, suitable for four-way medium diversion or confluence, allowing slight pipeline displacement, and effectively reducing vibration and noise. It is widely used in low and medium pressure fluid pipeline networks such as fire protection, HVAC, water supply and drainage, and municipal water supply, and is a mainstream choice for building electromechanical and overseas engineering.

| Customization | Our factory possesses full-dimensional non-standard customization capabilities for grooved cross fittings, and can comprehensively meet the needs of special working conditions at home and abroad, renovation of old pipe networks, and supporting requirements for high-end projects. We can customize grooved cross fittings with any non-standard reducing ratio, special opening positions, non-standard diameter combinations, and large-diameter reinforced pressure-bearing structures. We support surface process customization, including high-temperature-resistant anti-corrosion coatings, acid and alkali-resistant special spraying, food-grade polishing treatment, original-color passivation, and custom-color baking paint, adapting to humid, corrosive, and clean special environments. Special sealing rubber rings that are low-temperature resistant, oil resistant, and high-temperature resistant can be paired as needed, adapting to special medium transportation working conditions. Based on overseas drawings, dimensions of old dismantled pipe fittings, and special project parameters, we can perform reverse one-to-one customization of non-standard grooved cross fittings. We support laser marking, LOGO engraving, and batch coding. |
| MOQ | Our factory's grooved cross fittings adopt a flexible, low-threshold minimum order mechanism for foreign trade, fully accommodating the procurement needs of both large and small batches at home and abroad, with flexible ordering and no restrictions. For the conventional ductile iron red firefighting model and the hot-dip galvanized general-purpose model, the MOQ for mainstream specifications is as low as 1 piece, which can fully meet the needs of engineering trial samples, local pipeline network renovation, firefighting emergency repair replacement parts, project acceptance sample boards, small trial orders, and scattered replenishment. Common on the market |
| Lead Time | Our factory maintains a massive in-stock inventory of standard grooved cross fittings. Mainstream specifications including fire-red spray-coated, conventional hot-dip galvanized equal-diameter, reducing, and mechanical cross fittings are fully stocked. In-stock orders are shipped within 24 hours at extreme speed, quickly responding to overseas urgent orders, project rush work, pipeline network emergency repairs, and procurement needs with tight schedules. For conventional standard bulk orders, the process is mature and the automated production line has ample capacity, ensuring stable delivery times. |
| Packaging | Our factory's grooved cross fittings adopt export-oriented engineering-grade standardized protective packaging, specially customized to meet the wear resistance, impact resistance, paint loss prevention, moisture-proof and rust-proof requirements of cast iron pipe fittings.
