codes for penstock installation


Until a special penstock code is adopted, steel penstock practice is governed by appro- priate codes that apply to pressure vessels. penstock accessories, piers and anchors, and materials; fabrication, installation, specifications, and welding and corrosion control for penstocks.

Application guide of insulators for overhand lines with a nominal voltage over 1000V Part 3: DESIGN AND ANALYSIS OF ANCHOR BLOCK AND 5330:1984. The design of penstock is done using IS Code:11639(Part 1):1986. The code says about the numerous forces acting in the anchor block both in pipe full condition and pipe empty condition. The penstock design forces are also mentioned in the code. The sample design was done by hand calculation. 3.3 Design and Analysis

Let us compare by a single penstock and by a system of n penstocks. The fundamental condition of identical discharge can be realized by selecting diameters either, a) For identical flow velocities,

Upper Penstock shut-off and venting penstock = pipe. Sometimes omitted to save expense, it is highly recommended. Pipe failures do occur and it makes life a lot nicer to be able to shut the system down in a panic. Most any type of valve will work other than a plastic slide gate. INSTALLATION & MAINTENANCE INSTRUCTIONS - Install the rest of the bolts, and evenly tighten all of them. 5.2 Installation of stem extension, stem guides and floor stand 5.2.1 Procedure for open-frame and rising-stem configurations Once the penstock has been installed, the stem extension, stem guide(s) and the


1) Replace the penstock into position, ensuring not to damage the EPDM sponge seal 2) Re-position the penstock, checking all levels and that the inverts are aligned. 3) Follow the applicable instructions for the chemical anchors to install the penstock (see below) Follow the instructions supplied by the manufacturer of the chemical anchors.

mass for ease of installation. Quality & Testing To ensure that the sealing of the penstock is within our manufacturing tolerance and within the British Standard BS7775 requirements, the penstocks can be hydraulically batch tested for leak tightness and rigidity. Finite Element Analysis (FEA) Products are subject to FEA as part of their design.
