Cast cross fittings are cross-shaped four-way pipe fittings formed by integral casting. After the blank is formed in one piece, the structures such as ends, threads, flanges, and grooves are machined, which is different from forged, hot-pushed, and plate-welded fabricated pipe fittings. The materials we commonly produce include QT450-10 ductile iron, WCB cast steel, HT200 gray cast iron, and 304/316 stainless steel precision castings. Specifications cover DN25-DN600, conventional pressure ratings are PN10, PN16, PN25, working temperature is -20℃～300℃, and the main standards implemented include GB/T1348, GB/T12459, GB/T9439, ASME B16.1, ASME B16.3, MSS-SP-79, etc. Connection forms are divided into three types: grooved, flanged, and threaded. They are used for four-way medium diversion and merging in pipelines. Ductile iron cast cross fittings are mostly used in buried pipe networks for fire protection and municipal water supply and drainage, while cast steel and precision-cast cross fittings are used in ordinary chemical, water treatment, and general equipment pipelines. This product has a complex structure that is easy to form and is highly cost-effective, but it is not suitable for high-temperature, high-pressure, flammable, and explosive high-risk process pipelines.
- Integrally cast and formed, with no welds and no splicing defects, strong overall rigidity, and good resistance to ground settlement when buried.
- Uniform and thick wall thickness, stable pressure bearing, resistant to water flow erosion, and not easy to wear, burst, or leak under long-term water flow.
- Can be made into complex special-shaped structures, supporting customization such as non-standard diagonal crosses, special-shaped multi-ways, and extended straight pipe sections, which is difficult to achieve with forged and welded fabricated pipe fittings.
- Material options include QT450-10 ductile iron, WCB cast steel, HT200 gray cast iron, and 304/316 stainless steel precision castings, adapting to different working conditions such as ordinary water flow, sewage corrosion, and wear-resistant erosion.
- Connection forms cover the three mainstream types: grooved, flanged, and threaded, making it convenient to connect with existing pipeline systems.
- The surface can be hot-dip galvanized, plastic sprayed, plastic lined, or treated with anti-rust paint, adapting to buried and humid environments.
- Conventional DN50-DN200 grooved and threaded standard stock supports ordering from 1 piece, suitable for sporadic replenishment on construction sites and sample submission for inspection.
- The warehouse regularly stocks DN25-DN250 standard grooved, threaded, and flanged ductile iron crosses, shipping within 24-48 hours after order confirmation.

The warehouse keeps regular stock of DN25–DN250 standard ductile iron four-way fittings in grooved, threaded, and flanged types. After order confirmation, ultra-fast shipping is made within 24–48 hours, meeting the needs of construction sites racing to complete work. |
| Packaging | Cast cross fittings are heavy-duty civil engineering pipe fittings, with precision ports, a coating layer that is prone to knocks and collisions, and a cast iron surface that is prone to paint loss and wear. They are shipped with engineering-grade standardized packaging for dust prevention, knock prevention, and wear prevention, ensuring the intact rate during bulk transportation. Before leaving the factory, all cast cross fittings have flash and burrs removed, casting sand and slag cleaned, and impurities at the ports washed away, ensuring the pipe openings are flat and clean with no debris blockage. Black cast iron products are sprayed with special anti-rust protective oil to prevent moisture and rust during storage; hot-dip galvanized, plastic-lined, and powder-coated finished products are placed separately in isolation to prevent paint surface wear and galvanized layer scratches. Threaded ports are fitted with plastic protective caps to prevent thread damage from knocks and stripped threads, as well as dust accumulation and rust; grooved ports and flange sealing surfaces are individually covered with protective film to ensure installation sealing precision is not damaged. Small and medium-sized specifications use multi-layer bubble film |

FAQ
What is the difference between cast four-way fittings, welded four-way fittings, and forged four-way fittings?
Cast four-way fittings are integrally cast and formed, have no welds, have a thick structure, and are cost-effective, mainly serving medium- and low-pressure civil fire protection and municipal working conditions. Welded four-way fittings are mostly used for large-diameter medium- and low-pressure pipeline networks, while forged four-way fittings mainly serve ultra-high-pressure and high-temperature industrial working conditions. For ordinary water supply and fire protection pipelines, cast four-way fittings are generally preferred.
Can cast four-way fittings be used for buried installation?
Yes. Ductile iron cast four-way fittings are mostly used in buried pipeline networks for fire protection and municipal water supply and drainage, and their integrally formed structure performs well against ground settlement. For buried use, it is recommended to choose surface treatments such as hot-dip galvanizing, plastic lining, or anti-rust paint according to soil and media conditions. Please contact us to confirm the specific solution.
How should I choose among grooved, flanged, and threaded connection types?
Grooved connections install quickly and are mostly used for fire main lines and sprinkler systems; flanged connections are suitable for large-diameter buried main pipeline networks; threaded connections are mostly used for small and medium-diameter pipelines. Selection needs to be based on pipe diameter, pressure rating, and on-site installation conditions. You are welcome to provide working condition information, and we will assist in confirming.
Can cast four-way fittings be used on high-temperature, high-pressure, or flammable and explosive pipelines?
No. Cast four-way fittings are suitable for medium- and low-pressure, normal-temperature, high-flow working conditions, and are not suitable for high-temperature, high-pressure, flammable and explosive, or highly corrosive high-risk process pipelines. For such working conditions, forged pipe fittings are recommended, and we can assist in confirming the specific selection direction.
Can non-standard sizes and special-shaped structures be customized?
Yes. We support DN25-DN600 non-standard sizes, special wall thicknesses, unconventional reducing sizes, special pressure ratings, as well as non-standard diagonal four-way fittings, multi-way special shapes, extended straight pipe sections, special flange hole spacing, and special groove dimensions. We can produce with tooling according to drawings, samples, or technical agreements. You are welcome to contact us to confirm the details.
How long does it take to ship regular in-stock items?
The warehouse regularly stocks DN25-DN250 standard grooved, threaded, and flanged ductile iron crosses. Orders ship within 24-48 hours after order confirmation. Bulk orders and non-standard customizations follow the production scheduling cycle; for specific delivery times, please provide specifications and quantities for us to confirm.
How are warranty and after-sales handled?
Genuine products uniformly enjoy a 12-month official warranty. During the warranty period, in cases of non-human-caused overpressure, violent installation, or improper use, if problems such as casting defects, leakage and cracking, dimensional nonconformity, or anti-corrosion coating peeling occur, we will remake them free of charge, reship them free of charge, and bear reasonable logistics and engineering rework losses. Unused standard products support seven-day no-reason return and exchange, with after-sales response within 2 hours.
