Introduction to Carbon Steel Equal Tee

Carbon steel equal tees, also known as straight tees, welding tees, and same-diameter tees, are called differently in various regions, all belonging to the tee series.

Carbon steel equal tees are primarily used to alter fluid direction, commonly installed at the junction of main and branch pipelines.

Three-way fittings are pipe fittings, also known as three-way pipe fittings or pipe fittings three-way, three-way connectors, used where the main pipeline branches off.

A three-way is a type of industrial piping fitting with three openings: one inlet and two outlets; or two inlets and one outlet. It comes in T and Y shapes, with both equal and unequal diameter pipe ends, used at junctions where three identical or different pipelines converge.

Carbon steel equal tee differs from carbon steel reducing tee in that the three pipe openings of an equal tee are the same size, whereas a reducing tee has the main pipe size being the same, with the branch pipe size being smaller.

Manufacturing Process

Hydraulic胀forming: Hydraulic胀forming, also known as cold drawing molding tees, is a forming process that uses axial compensation of metal materials to胀出 branch pipes; the hydraulic胀forming process for tees can be formed in one go, offering high production efficiency; the main pipe and shoulder wall thickness of the tee are both increased.

Hot Pressing: Hot pressing for tees involves flattening a pipe blank larger than the tee diameter to approximately the tee diameter, then drilling a hole at the location of the extension branch. The pipe blank is heated, placed into a forming die, and a punch mold for the extension branch is inserted inside. Typically used for tees with large diameters and thicker walls, this forming process is commonly employed.

Application Fields

Due to the excellent comprehensive properties of carbon steel equal tees, they are widely used in fundamental projects such as chemicals, construction, water supply, drainage, oil, light and heavy industries, refrigeration, sanitation, plumbing, fire protection, power, aerospace, shipbuilding, etc.

Procurement Recommendations

1: We recommend purchasing from a reputable three-in-one (3-in-1) manufacturer, ensuring they have a substantial production scale.

2: Manufacturers of tees require material inspection reports and other relevant documents for the tees.

3: Tee fittings must have corresponding specifications, model, and embossed identification marks.
