How to machining tubesheet in special materials

How to machining tubesheet in special materials

The tubesheet used for class III and IV pressure vessels needs relatively high precision. The traditional hole processing methods are bench marking and rocker drilling.

Tubesheet specification and design size

Tubesheet specification and design size

In the calculation of fixed tubesheet, the axial stress of shell, the axial stress of heat exchange tube and the pull-out force Q between heat exchange tube and tubesheet are calculated according to various working conditions with temperature difference.

Tubesheet in special materials application

Tubesheet in special materials application

Tubesheet in special materials is to drill holes slightly larger than the outer diameter of the pipe on the circular steel plate. It is a round steel that plays the role of fixing the pipe and sealing medium in the heat exchanger. It is a kind of fitting

A588 Grade C weathering steel plate

A588 Grade C weathering steel plate

A588 Grade C weathering steel plate has a more important market in the production process, and it is also a more important production process. Because A588 Grade C weathering steel plate has always played a more important role in the production, so the pr

Production process of ASTM CortenB weathering steel plate

Production process of ASTM CortenB weathering steel plate

ASTM CortenB weathering steel plate is made by adding phosphorus, nickel, copper and other trace elements to ordinary steel plate in the smelting process. A dense and highly protective film is formed on the surface of ASTM CortenB weathering steel plate,

Why can weather resistant steel plate be used on the bridge?

Why can weather resistant steel plate be used on the bridge?

Corrosion resistance: A lot of bridge design is close to the surface, some even cross-sea bridge, both the sea and the river, how much will appear high tide phenomenon, thus to drown of bridge deck, this material have higher requirements for bridge, if us

UNI Fe 510 C2K1 weathering steel plate welding

UNI Fe 510 C2K1 weathering steel plate welding

During the welding process, the UNI Fe 510 C2K1 weathering steel plate butt joint weld toe was repaired and (annealed). The microstructure, mechanical properties and residual stress after welding were compared and analyzed. The results showed that the wel
