Tee 315/150 for round channels, GOST 24751-81, SNIP2.04.05-91, European standard,

Ventilation round tee 315/150 is designed for connecting an air duct with a diameter of 315 mm to an air duct at a right angle with a diameter of 150 mm.

A galvanized steel tee is a shaped part designed for branching a line of air ducts (i.e., for branching one air flow into two or combining two flows into one). In order to connect various air ducts to each other and combine them into complex ventilation systems, special shaped products are used - tees.

Air ducts and shaped products are made of galvanized steel with a thickness of: p = 0.55 ( - 100-355 mm); p=0.7 ( - 400-800 mm); p=1.0 ( - 900-1600 mm). To ensure the rigidity of air ducts with diameters greater than 315 mm, additional stiffening ribs are provided (intermediate zig).

Air ducts and fittings are made of galvanized steel with a thickness of: p=0.55 (- 100-355 mm); p=0.7 ( - 400-800 mm); p=1.0 ( - 900-1600 mm). To ensure rigidity of air ducts with diameters greater than 315 mm, additional stiffening ribs (intermediate zig) are provided.

This material is not susceptible to corrosion. The element is made with a margin of safety, which will allow you to repeatedly disconnect and reattach the tee to the air duct or vice versa.

Connection of air ducts:

• nipple using sealant (silicone), with fixation with self-tapping screws or rivets. The nipple is used only for connecting straight sections.
• shaped products are connected using a coupling. 

Manufacture of air ducts and products from galvanized steel to order:

In-house production of air ducts and products made of galvanized steel for ventilation, aspiration and air conditioning systems with a thickness of 0.4 - 1 mm:

• Air ducts rectangular cross-section (rectangular air ducts);
• straight-seam circular air ducts (round air ducts);
• Shaped products (bends, half-bends, tie-ins, tees, transitions, etc.)
• We carry out selection, calculation of air ducts, design and provide technical consultations
