Stainless steel seamless tee

Stainless steel seamless tee is an important pipe fitting used in pipeline systems. The following is a detailed introduction about it:

Structural characteristics

Overall structure: composed of a main pipe and two branch pipes, forming a "T" or "Y" shape. The connection between the main and branch pipes adopts seamless transition without welding seams, which protects the smoothness and sealing of the pipeline system.

Port form: Ports are usually circular and can be connected to pipelines in various ways, including welding, threaded connections, and sleeve connections. Welding ports are generally processed with grooves to protect the quality of the weld seam during welding; Threaded ports come with standard threads and can be connected to corresponding threaded pipes or fittings; The card sleeve connection port is connected at a suitable speed through a card sleeve type connector, which has the characteristics of easy disassembly.

manufacturing process

Hot pressing: This is one of the main methods for manufacturing seamless stainless steel tees. Place the stainless steel billet heated to a certain temperature into the mold, and apply pressure through a press to deform the billet in the mold, forming a three-way shape. This process can protect the dimensional accuracy and internal quality of tees, and is suitable for manufacturing seamless tees of various specifications.

Cold drawing forming: For some small-sized stainless steel seamless tees, cold drawing technology can also be used. The pre treated stainless steel tube blank is cold drawn through a mold, gradually forming a tee shape under the action of the mold. Cold drawn tees have good surface quality and dimensional accuracy, but their production efficiency is relatively low, making them suitable for applications that require high precision.

Welding combination: In some special cases, seamless tees may also be manufactured by welding combination. First, manufacture the main and branch pipes separately, and then connect them together through a welding process with appropriate precision to form a seamless tee. This method requires strict control of welding quality to confirm the seamless performance and overall strength of the tee.

Advantages: It has good corrosion resistance (mainly based on actual reports), can resist the erosion of various chemical media, and is suitable for pipeline systems that transport corrosive liquids and gases; Due to the seamless structure, the tee has good strength and can withstand high pressure and impact forces, protecting the safe operation of the pipeline system; Smooth internal surface and low fluid resistance are beneficial for improving fluid transport efficiency and reducing energy loss; Long service life reduces the frequency of maintenance and replacement of pipeline systems, and lowers operating costs.

Stainless steel seamless tees are widely used in pipeline systems in industries such as petroleum, chemical, pharmaceutical, food, beverage, water treatment, and power. In the petrochemical industry, it is commonly used to transport various petrochemical raw materials, finished oil products, and natural growth gas; In the pharmaceutical and food industries, due to its excellent corrosion resistance (based on actual reports) and hygiene performance, it is suitable for transporting various drugs, food and beverages, etc; In the water treatment industry, it can be used to transport various corrosive water treatment agents and purified water.
