2. ARRANGEMENT

All piping shall be installed in accordance with ANSI Code for pressure piping B 31.1 or B 31.3 as applicable and this TAMSA Engineering Standard.

Overhead piping shall be grouped in banks and arranged to facilitate supporting and provide easy maintenance.

Piping connecting equipment shall be designed to permit ready removal of equipment without additional support of pipe.

Underground pipe lines shall be installed on solid fill and be kept clear of any major foundations.

3. ACCESS AND CLEARANCES.

All valves shall be located for ease of operation and accessibility. Where valves are not accessible, extension stems or chain wheels shall be used when valve center lines are longer than 2,150 mm above grade or floor.

Sufficient clearance around control valves shall be provided to allow remotion of parts without removing valve body from line. Control valves shall be accessible from platforms, walkways or grade.

4. SUPPORTING.

Nomenclature

PS- Pipe support, guide, hanger or anchor (see detail on particulars drawings).

FS- Field support (suitable support shall be supplied in field).

FG- Field guide (guide allowing only axial movement shall be supplied in field).

All saddles and anchors shall be installed in field (unless otherwise shown) in accordance with the drawings.

Piping to pumps, compressors and their drivers should be anchored close to the equipment to prevent thermal strain and misalignment.

Location of pipe supports, guides, hangers and anchors are shown on piping drawings. Flanges and field welds will be so located as to leave a minimum clearance of 300 mm between pipe supports.

Pipe suports, guides, hangers or anchors shall be identified by various tag numbers I.E. PS3-PS4 etc., in which “PS” is the pipe support designator, “3” & “4” etc., are pipe support numbers. For convenience in detailing fabrication and erection, the tag numbers are shown on the structural steel and piping drawings.

Pipe sleeves shall be provided for all piping passing through foundations, walls, floors, roofs, etc. weather shields shall be located at all openings throught the roof.

5. PIPING.

Identification.

All piping shall be identified by various service codes. Pipe lines shall be identified as follows:

Valves Identification.

All valves shall be identified by variious service codes as follows:

The valves list will include:

• Valve identification.

• Diameter.

• Line number

• TAMSA valve code.

Piping, Flanges & Fittings.

No carbon steel pipe of the following sizes shall be used: 3/8”, 1 1/4”, 2 1/2”, 3 1/2”, 4 1/2”, 5”, & 7”, except otherwise specifically required. Pipe wall thicknesses shall be calculated in accordance with ANSI B31.1.0 (present issue).

Flanges shall be kept to a minimum except as indicated by the following service or location:

• At equipment valves.

• Spool pieces to allow easy maintenance or repairs without having to cut pipe lines.

• Other lines as indicated by Engineer.
