178.61 Specification 4BW welded steel cylinders with electric-arc welded longitudinal seam. (a) Type, size and service pressure. A DOT 4BW cylinder is a welded type steel cylinder with a longitudinal electric-arc welded seam, a water capacity (nominal) not over 1,000 pounds and a service pressure at least 225 and not over 500 psig gauge.
Get PriceLongitudinal Stresses 2 2 2 o i i i l r r p r − s = The longitudinal stress is simply given by a Force/Area, where the Force is p i times the circular inside area πr i 2, and the Area is the annular area of the cylinder cross section, π( r o 2 - r i 2), or: This is generally only considered for the case of internal pressurization ( p o
Get PriceClosed End cylinder: In the case of closed-end cylinder subjected to internal and external pressures, longitudinal stress exists in addition to the radial and tangential stresses. For a transverse section some distance from the ends, this stress may be assumed uniformly
Get PriceCylinder axial stress calculator - formula step by step calculation to find the longitudinal stress developed along the cylinder or pipe having both ends closed due to the internal pressure. σ L = (P x d)/(4 x t). The internal pressure act on cylinder or pipe to develope the force along the axis of cylinder or pipe is called axial or

Get PriceSolve circumferential and longitudinal stresses in thin walled cylinders. A cylinder is regarded as thin walled when the wall thickness t is less than 1/20 of the diameter D. Consider a small rectangular section of the wall of a thin walled sphere. There are two stresses
Get Price(ii) For a cylinder made of seamless steel tubing with integrally formed ends, hot drawn, and finished, content percent for the following may not exceed: Carbon, 0.55; phosphorous, 0.045; sulfur, 0.050. (iii) For non-heat treated welded steel cylinders, adequately killed deep drawing quality steel is required. (iv) Longitudinal or helical welded cylinders are not authorized for service
Get PriceThe range of validity of this kind of approximation cannot be easily determined, and the availability of rigorous reference solutions is of great importance for validating approximate procedures. The main purpose of this paper is to derive a rigorous modal solution for the case of circular cross-section cylinders with longitudinal corrugations.
