How many millimeters is the diameter of one inch pipe?
The 1 inch tube corresponds to DN25, and the standard outer diameter is 33.4mm. But 32mm is also OK in usually application.
The nominal diameter(also known as nominal diameter and nominal diameter) is used in order to make the pipe and pipe fittings unify.
For example, the thickness of welded pipe can be divided into thin wall steel tube, ordinary steel pipe and thickened steel tube. Its nominal diameter is not an outer diameter or an inner diameter, but a nominal size approximating the inner diameter of a common steel tube.
The diameter of each nominal diameter corresponds to a diameter, and its inner diameter varies with the thickness. The nominal diameter can be expressed in the metric "mm (millimiter)" and can be expressed by the British "in (inch)" .

1 inch steel tubes can be used widly in our daily life
(1)construction engineering
Water supply/drainage systems: Galvanized layer prevents corrosion in water pipelines.
Structural supports: Stair handrails, scaffolding cross-members for outdoor durability.
(2)Energy and Power
Cable protection conduits: Resists moisture and chemical corrosion in buried lines.
LPG pipeline brackets: Meets anti-corrosion and explosion-proof requirements.
(3)Agricultural Water Engineering
Farm irrigation systems: 1-inch diameter compatible with sprinklers, resists fertilizer corrosion.
Livestock fencing: Smooth surface for easy cleaning.
(4)Special Industrial Scenarios
Auxiliary pipes for chemical equipment: For non-corrosive media like cooling water.
