Special Item: Welded Pipe Fitting "Cross"

Instead of machining, we can reduce costs by manufacturing from seamless pipes!

In the variety of welded pipe fittings, elbows, Ts, and reducers are common, but fittings that have branches on the top and bottom resembling a T are referred to as crosses due to their cross-shaped design. This type of pipe fitting is not specified in JIS standards and is mostly manufactured by machining from forged materials. However, Benkan Kiko is capable of producing them using the bulging method (hydraulic forming) from seamless pipes. The machining method tends to result in heavier weights and often produces angular shapes, which can make welding at construction sites difficult. Additionally, the method of machining from a solid block requires a significant amount of material, leading to higher material costs and increased processing costs. Manufacturing through shaping from seamless pipes allows for smooth shapes, uniform wall thickness, and lighter product weights, while also achieving cost reductions. This cost advantage becomes more pronounced with high-cost materials such as stainless steel and non-ferrous metals like nickel, resulting in significant benefits.

basic information

A cross is a symmetrical, cruciform welded pipe fitting. It is used in piping construction to branch fluid in four directions. Other methods of branching in four directions without using a cross include drilling holes on both sides of the pipe and directly welding the pipes together, or using pipe supports, among others. In these cases, the pipes being joined are often of a smaller diameter than the original pipe. The crosses from Benkan Kiko have the same diameter and wall thickness in all four directions, and the ends are prepared for butt welding, allowing for branching under the same conditions as the main piping. Manufacturing range: Outer diameter: 1/2 to 8B *Products outside the above sizes may also be available, so please contact our sales department for more details.
