Hksteelcorporation is a prominent manufacturer of stainless steel cross, carbon steel cross and alloy steel cross fittings, commonly known as a 4-way pipe fitting. Cross tee usually generates high stress on pipe as temperature changes, because they are at the center of four connection points. In comparison, a tee is steadier than a cross, as a tee behaves like a three-legged stool, while a cross behaves like a four-legged stool.
