What is pipe Tee?

Pipe tee as one type of pipe fittings plays a very important role in pipelines. It can connect the pipes with same or different diameters from three directions. Quality fully guarantees the safety of pipe tee that will refer to the safety of the whole pipeline.

Pipe tee can be made of different materials carbon steel, alloy steel and stainless steel are the most common. The choice for material is decided by the project design and the fluid transported in the pipelines. Carbon steel pipe tee is widely used for the pipelines with general usage middle and low pressure. Alloy steel pipe tee is specially applied for high temperature and pressure pipelines. And the stainless steel pipe tee is mainly used for the pipelines that transport the corrosion fluid because of its resistance to corrosion.

For the production process of pipe tee there are two ways cold forming and hot forming. No matter which way pipe tees are all extruded the branches from the main pipes. That decides pipe tee easily cracks compared with other pipe fittings. So pipe tee must proceed hot treatment and 100% inspection before delivery.

Applications

  • Natural gas pipeline

  • Oil pipeline

  • Chemical Pipeline

  • HVAC Piping

Technical Specifications

Butt weld pipe tee has many sizes no matter for carbon steel or stainless steel. The following information is just about their sizes and tolerances.

The types of butt weld pipe tee according to standards

ASME tee

Butt weld pipe tee ASME B16.9 is the tee produced according to the standard of the American Society of Mechanical Engineers. It is the most popular standard for butt weld pipe fittings which is being used by most countries in the world.

DIN tee

Butt weld pipe tee DIN2615-1 or DIN2615-2 Deutsche Industrie Norm. Pipe tee DIN2615-1 generally the internal pressure reduced than the pipes with same diameter. But pipe tee DIN 2615-2 has the same pressure as pipes.

JIS B2311, B2312, B2313 tee

Butt weld pipe tee JIS B2311, B2312, B2313 is the tee produced according to Japanese Industrial Standards. B2311 is for the pipe tee with general service. B2312 is for the pipe tee used for high temperature, high pressure and low temperature.

other standards tee

Except for the ASME, DIN, JIS standards, there are also several different standards, such as EN10253, ISO15590, GOST17376, Korea standard and so on. You can choose products based on actual situations.

Classify butt weld pipe tee according to material

Carbon steel butt weld pipe tee

Carbon steel butt weld pipe tee is generally made of carbon steel pipes or carbon steel plates. This kind of material commonly is not applied to special purpose, so these pipe tees usually are for middle and low pipelines normal temperature.

Alloy steel butt weld pipe tee

Alloy steel butt weld pipe tee, its mother materials are alloy steel pipes or steel plates that are specially used for the pipelines taken at high temperature and high pressure. An alloy steel pipe tee also has the feature of high strength.

Stainless steel butt weld pipe tee

Stainless steel butt weld pipe tee, just as its name implies the raw materials are corrosion-resistance. The common materials refer to 304/304L, 316/316L, 321/321L etc. This kind of pipe tees are often put in the pipelines of corrosion fluid.

Seamless butt weld pipe tee and weld pipe tee

Seamless butt weld pipe tee

Seamless butt weld pipe tee is produced by seamless steel pipes the size range is from ½” to 24”. In order to guarantee the tee doesn't crack while using heat treatment is mandatory, that can improve the mechanical performance.

Weld pipe tee

Weld pipe tee is generally the size above 24” and produced through heating steel plate forming and welding. X-ray testing is necessary for weld pipe tee in order to avoid the lack of weld.

Features

Butt weld pipe tee as a common and functional pipe fitting, it has several special features. Please see the introduction in the below.

Multi-functionality

Tee can connect different pipes to achieve the flow diversion or convergence of the fluid. It is easy to manage and control the flow of fluid.

Simple structure

Tee has two main pipes and one branch pipe, which can be in the shape of T-shaped or Y-shaped. It is easy to install and disassemble, and easy to repair and maintain.

Fluid distribution balance

The design of the tee guarantees the balance of fluid distribution between branch pipe and main pipe.

Flexible to choose diameter

The tee allows the user to choose the diameters as their actual needs no matter the same or different sizes for branch and main pipes.

Good strength and sealing performance

Due to the end of the tee was treated which ensured the tightness of pipe connection and avoided leakage or cracking.

Saving material

In the design of piping systems, pipe tee can combine multiple pipes into one to maximize the utilization of materials, there by achieving the purpose of saving resources.

Pipe Tee Customization Options

Customization is available. Metleader can provide flexible customized production service according to the drawings or technical data from clients to meet special requests.

Quality Assurance

1) Raw material inspection: We have the corresponding CQ system and reference standards. Before the raw materials into warehousing, we will carry out chemical analysis and mechanical property testing. If the testing result is unqualified, the raw materials will be return to the suppliers.

2) Technology inspection: In the production process, there are many testing items aimed at the pipe tees, such as diameter, wall thickness, ovality, DIN inspection, mechanical testing, etc. All of these testing items are according to the specification standards to ensure the quality of pipe tees.

3) Heat treatment and 100% inspection: Pipe tees are extruded the branches from the main pipes, and it is easier to cracks compared to other pipe fittings. Therefore, in order to reduce the risk of cracks, the pipe tees must be heat treated and 100% inspected before delivery to improve the mechanical properties.
