Products Details
Ductile iron Grooved pipe fittings Equal Tee. The material is ductile iron. The
connect method is Grooved connection. The Grooved Tee also called DI Grooved tee.
Grooved Tee have Grooved tee short, Grooved tee long radius 90 degree. Grooved
Reducing Tee, Grooved tee with Thread outlet, also called Thread Grooved Tee,
normaly the branch outlet is thread end ,the main outlet is Grooved end. According
to the surface coating ,dip painting Grooved Tee red color ,epoxy red color
Grooved Tee ,epoxy blue color Tee ,galvanized Grooved tee.

Grooved pipe surface requirements
The surface of grooved pipe fittings should be flat and smooth, and defects such
as pores, sand holes, slag inclusions, cold partitions, shrinkage holes, cracks,
and depressions that affect the performance are not allowed. There are no defects
such as bulges and depressions in the casting groove. There are no processing
defects and bump damage in the processing parts of grooved pipe fittings. The logo
is clearly recognizable.

The surface of grooved pipe fittings should be treated with anti-corrosion
treatment by dipping paint, spraying, hot-dip galvanizing, etc.:
a) Paint layer. It should be uniform, smooth and firm, without lacquer tumor,
paint accumulation and paint leakage, the thickness of the paint layer is not less
than 25.4μm, and the lead content of the paint layer is less than 0.009%.
b) Plastic layer. It should be uniform, continuous, smooth and firm, and should
not be flammable when applied to fire protection systems. The thickness of the
plastic layer is not less than 40μm.
c) Hot-dip galvanized layer. The zinc layer on the surface of galvanized groove
pipe fittings should be uniform and continuous smooth, and there should be no
defects such as zinc leakage, zinc layer falling off, and black spots; The contact
surface with the rubber ring/pad is not allowed to have appendages such as zinc
tumor, zinc slag, pile zinc, etc., and the lead content of the zinc layer is not
more than 0.1%. The minimum zinc layer thickness is 63 μm.
Bolts and nuts should be hot-dip galvanized, electro-galvanized and other anti-
corrosion treatments:
a) Electro-galvanizing. The electroplating layer has a bright luster, and the zinc
layer is uniform and complete, there must be no zinc leakage and rust spots
locally, and the thickness of the zinc layer is not less than 8μm.
b) Hot dip galvanizing. Hot-dip galvanizing should comply with the provisions in
GB/T5267.3, the surface should be smooth, no leakage plating surface, zinc tumor,
black spots, no residual solvent residue, oxide scale inclusions and other defects
that damage the intended performance of parts. The thickness of the zinc layer is
not less than 40μm.

Application and Case
Products are used in fire protection system, water system, HVAC system, plumbing,
gas system, irrigation system, etc. These products are used in many projects ,
such as China Taiwanese Building 101, Xiamen Building, Wuhan Expo Building and
other famous landmark projects.
