One-Minute Overview

Butt weld equal tee that keeps all three legs at one nominal diameter.
Offered in carbon, stainless, alloy and duplex steel to suit the medium.
Sizes and wall schedules matched to line pressure and temperature.
A standard branch fitting for oil, gas, power and chemical lines.

A BW equal tee is the butt weld fitting that splits or combines flow while keeping all three legs at the same diameter, so the flow rate stays even in every direction. Qishine makes it from carbon steel, stainless steel, alloy steel and duplex steel: carbon steel for general strength and cost, stainless where corrosion and oxidation matter, alloy for hotter duty, and duplex where strength and corrosion resistance have to come together. The tees are formed to give a uniform wall, then supplied across a range of diameters, wall thicknesses and schedules so the branch matches the pressure and temperature the line actually sees. Typical homes are oil and gas pipelines, power plants and chemical processing plants.

Name: BW Equal Tee
Type: Butt weld equal tee
Material: Carbon Steel, Stainless Steel, Alloy Steel, Duplex Steel
Configuration: Equal run and branch
Sizes, wall schedules and end preparations are confirmed per inquiry, and a detailed specification sheet is available on request.

Material is the first choice, and it follows the fluid. Carbon steel is the economical default for oil, gas and utility lines where corrosion is manageable; stainless steel earns its place when the medium attacks iron or the plant has to stay clean; alloy steel covers the higher-temperature band; and duplex steel combines strength with resistance to chloride and sour service. Match the tee grade to the run pipe so the weld is between compatible metals and the corrosion allowance is the same on both sides of the joint. Then set the wall schedule from the design pressure and temperature, not from habit: a light tee in a heavy line is the weak link, and an over-heavy one wastes both material and welding time.

Because this is a butt weld fitting, the branch is only as good as the preparation. Order the ends bevelled to the joint design, cut the pipe square, and hold an even root gap so the three-way intersection lines up without forcing it. Align the branch square to the run, tack it, and weld with a procedure qualified for the chosen grade - stainless and duplex in particular dislike excess heat input and contamination from carbon steel tools, so keep the brushes and grinders dedicated. After welding, inspect the bead, check the bore is clear, and add the nondestructive examination the design code calls for. Keep the four material grades segregated in the store so nobody welds the wrong tee into a line during a turnaround.

FAQ

Q1. Four materials - is this a menu or a fitting?

A short menu, admittedly. The grade follows the fluid: carbon steel for ordinary oil, gas and utility duty, stainless for corrosive or clean service, alloy for higher temperatures, and duplex when you want strength and chloride resistance in one body. Pick the one that matches the run pipe, because the weld is happiest between compatible metals and a mismatched grade quietly becomes the weak spot in an otherwise sound line.

Q2. How should the wall schedule be selected?

From the design pressure, temperature and corrosion allowance of the line, not from what was ordered last time. The schedule has to be at least as heavy as the pipe it joins, so the branch does not become the thinnest point in the spool. If the system sees both low and high pressure sections, specify the schedule per section on the drawing rather than buying one wall for the whole header and hoping it covers the worst case.

Q3. Any traps when welding the branch on?

A few, and alignment is the big one. Cut the pipe square, bevel both ends the same way, and keep the root gap even all the way round or the branch will pull the run out of line. Use a procedure qualified for the grade, and with stainless or duplex keep carbon steel tools away from the joint so you do not embed free iron. Then check the bore and let the required nondestructive examination close the job.

Q4. How long will production take?

Standard sizes are typically ready within 30 days, and in-stock items ship immediately. Larger or custom orders get a confirmed date per order, because the schedule depends on quantity, material, the bolt pattern you specify, and how busy production is at the moment you order.
