STRAIGHT LENGTHS

TECHNICAL DATA

 CORRECT STRAIGHT LENGTHS (CSL)

     Correct straight length are tubes which have been mechanically straightened and then cut to specific lengths as specified by the customer.

CORRECT STRAIGHT LENGTHS – Produced in the following outside diameter size ranges.

MIN. DIAMETER -- 3/16” (4.76 MM)

MAX. DIAMETER -- 1-1/18” (28.58 MM)

MIN. LENGTH -- 6” (152.40 MM)

MAX. LENGTH – 25’ (7.62 M)

Cleanliness: Annealed straight lengths meet or exceed the cleanliness levels of ASTM B-280. Lengths are capped with plastic ends caps when so specified by the customer.

Tolerances: Exact straight lengths are produced to the dimensional tolerances specified in ASTM B-251. Closer tolerances may be available, provided that prior agreement is reached between the customer and MANDEV.

Box Weights and Packaging: Exact straight lengths are provided and packed as per customer’s requirements.

End Finish: Straight lengths are supplied with a commercial saw cut with minimum burrs as standard. A mechanically deburred end is available on request at added cost.

Tempers: Exact straight lengths are provided in the following tempers and grain sizes: hard drawn, dead soft, soft annealed, light drawn and light annealed.  

TEMPERS

      The following are available depending on the product form. Consult specific data listed for each product to determine which tempers are available.

1. Hard Drawn (H80): No visible grain – used where minimal forming will be performed and maximum strength is required.
   

2. Dead Soft: .070 mm grain and above – this is a large grained product and used where the product is cold worked repeatedly. This temper work hardens at a much at a slower rate but is not suitable for extreme forming.
   

3. Soft Anneal (060): .040 -- .060 mm grain – this temper is suitable for general purpose bending and forming which is not as extreme as that requiring light annealed temper. Soft anneal temper works hardens at a slower rate than light anneal.
   

4. Light Drawn (H55): .015 -- .040 mm  grain – this temper is similar to light annealed or light annealed rotary straightened, but has a much higher yield strength due to drawing after annealing. This product is used where high rigidity is desired with minimal amount of forming ability.
   

5. Light Anneal (050): .015 -- .040 mm grain – preferred for tight bends and extreme forming application. This is an annealed temper with a fine grain size to prevent “orange peel” and fracturing when forming.
