How do you calculate coil length?
How do you calculate coil length?
To calculate spring wire length per coil, you must subtract the wire diameter from the outer diameter in order to get mean diameter. Once you have calculated mean diameter, multiply it by pi (3.14); this will give you the length of wire per coil.
How many meters is a coil?
1 Sq.mm Fire Retardent (fr) V Gaurd 1 Sq.mm Fr House Wire 90 Meters Packing Coil, Rs 668 /meter, ID: 15010121333.
How is PIW calculated?
To determine the theoretical weight of a coil, measure the ID and OD of the coil. Determine the PIW (pounds per inch) from the chart below. Then multiply the PIW by the width of the coil in inches….PIW Calculator.
| Outer Diameter | 16″ Inside Diameter weight per inch | 20″ Inside Diameter weight per inch |
|---|---|---|
| 69″ | 1003 | 970 |
| 70″ | 1034 | 1001 |
What is free length of spring?
The free length of a spring is the actual length of a spring when no force is being applied to it (it is not being deflected). For compression springs, you simply multiply the length of the spring wire per coil by the total number of coils.
Which meter use a moving coil for measurement?
Analog multimeter It is a multifunction instrument that can measure current and resistance as well as DC and AC voltage signals. Basically, the instrument consists of a moving-coil analog meter with a switchable bridge rectifier to allow it to measure AC signals, as shown in Fig. 10.6.
How do you find the free length of a spring?
To get the free length of a torsion spring, you multiply the length of the spring wire per coil by the total number of coils and add the lengths of the legs.
What is coil PIW?
(PIW) – Designates pounds per inches wide of a coil. Determined by taking the coil weight and dividing by the width (Example 5,400 lbs. coil at 45” wide = 120 PIW).
What are the dimensions of the coil?
The geometry of the coil depends on certain factors such as internal diameter, external diameter and width. The inside diameter depends on the recoiler and usually has one of these standard values: 152 mm; 254 mm; 305 mm; 406 mm; 508 mm; 610 mm . Width can be trimmed on request, but is usually in one of the standard sizes: 1000, 1250, or 1500 mm.

How long does ppgi&ppgl deliver to China?
1000mm, 1200mm width PPGI&PPGL, we can deliver to the China departure port within 2 weeks after your order. The Steel Coil Calculator can be used for Carbon Steel, Galvanized Steel, PPGI, Aluzinc Coils. The calculated results are only to be used as a guide and cannot be guaranteed.
Can I trim the width of the coil?
Width can be trimmed on request, but is usually in one of the standard sizes: 1000, 1250, or 1500 mm. On the other hand, if we do not have the dimensions of the coil but only the total weight, thickness and width of the sheet, we can still obtain the length of the sheet.
