Support types i.e. whether hanging type, foot mounted type etc. Special features such as travel limit stop required if any. Preferred surface protection / paint / finish. Hot load is the working load of the support in the “Hot” condition i.e. when the pipe has traveled from the cold condition to the hot or working condition.
The support structure for the shading systems can be normal systems as the weight of a standard PV array is between 3 and 5 pounds/ft 2. If the panels are mounted at an angle steeper than normal patio covers, the support structures may require additional strengthening. Other issues that are considered include: Simplified array access for ...
The tapped-hole rack was first replaced by clearance-hole (Round Hole, Round Unthreaded Holes, [11] and Versa Rail [12]) racks. The holes are large enough to permit a bolt to be freely inserted through without binding, and bolts are fastened in place using cage nuts. In the event of a nut being stripped out or a bolt breaking, the nut can be ...
When driving on the road, one needs to load the allowed weight minus the weight of the roof rack kit. If one plans to use the roof racks for off-road driving, the allowed weight should be divided by 2, and this will be the maximum amount to be carried on the roof racks in such driving conditions. A truck bed rack is a derivation of a roof rack ...
A fixed roof tank is a type of storage tank, used to store liquids, consisting of a cone- or dome-shaped roof that is permanently affixed to a cylindrical shell. Newer storage tanks are typically fully welded and designed to be both liquid- and vapor-tight. Older tanks, however, are often riveted or bolted, and are not vapor tight.
An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate. It consists of an open- topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. The roof rises and falls with the liquid level in the tank. [1]
Positive end-expiratory pressure (PEEP) is the pressure in the lungs (alveolar pressure) above atmospheric pressure (the pressure outside of the body) that exists at the end of expiration. [1] The two types of PEEP are extrinsic PEEP (PEEP applied by a ventilator) and intrinsic PEEP (PEEP caused by an incomplete exhalation).
Occasionally, pipe racks may also support mechanical equipment, vessels and valve access platforms. Main pipe racks generally transfer material between equipment and storage or utility areas. Storage racks found in warehouses are not pipe racks, even if they store lengths of pipe. [1] A pipe rack is the main artery of a process unit.
