Tube Channel

Spherical diaphragm seal dish of tube channel open end in high pressure heat exchanger is a new engineering structure that used in petrochemical hydrogenation unit, and its design technology is not reported now. It is inconvenience to analyze each case by limited element method. Design method of formulas is proposed to calculate both radial offset displacement and its thickness of spherical diaphragm based on shell elasticity mechanics. Relation formulas are deduced about arch height, open end radius, offset displacement by geometry. Two presuppositions are deduced for spherical diaphragm successful to run according to technology theory and function analysis of seal dish structure, which can be used for engineering design.

End Distance

An experimental study was undertaken to verify the combined effects of timber connector end distance and spacing requirements of the Canadian standard for engineering design in wood. A total of 130 test specimens using 63 mm diameter split rings were loaded to failure in tension. The split ring end distance varied between 50 and 210 mm and the spacing varied between 80 and 200 mm. Results show that a linear relation exists between the connector end distance and its resistance for a given spacing. Increase in spacing also results in an increase of the connector resistance for a given end distance. Also, connections with two connectors in a row can resist significant loads even if the end distance or spacing of one connector is below the standard minimum required value. Thus, the design philosophy of Clause 10.3.3 of the wood design standard is inadequate for these joints. Key words: split ring, tension, end distance, spacing, resistance, timber.
