Astm A252 Piling Pipe,A252 spiral pipe,A 252 SSAW/ERW pipe

This specification covers nominal size from the wall steel tubing piles of cylindrical form and applies to pipe piles in which the steel cylinder works as a permanent load-carrying member. Alternatively, as a casing to kind cast-in-place concrete piles.

Independence Tube is now producing ERW Steel Pipe Piling to ASTM A252 in Marks 1, Grades two, Levels 3. Piling Pipe is made from 6.623" O.D. to 26" O.D. in walls from .198" to .772" up to 78 feet lengthy.

SCOPE

This specification covers nominal thickness of your wall steel pipe piles of cylindrical shape and applies to pipe piles in which the steel cylinder acts as a permanent load-carrying membere Alternatively, as a shell to type cast-in-place concrete

By far the most well-known Pipe Piling sizes of 10.75" 12 and OD.75" OD are produced in our hebei province ,cangzhou city ,china.2 week production cycle for the quick desires.

The 14" and 16" OD piling sizes are produced in our SINDAPIPE.

When it comes to the versatility of designing with tube and pipe goods

STEEL CHEMICAL COMPOSITION

The metallic shall conform towards the following requirements as to chemical composition:

Seamless and welded pipe : Martin furnace, basic-o2 or electric furnace:

Phosphorus, maximum (%) : .050

MECHANICAL PROPERTIES

Tensil strength, minutes. psi (MPa): 50,000 (345) 60,000 (414) 66,000 (455)

Elongation in 2 in., min. Per cent : 30% 25Per cent 20%

PERMISSABLE VARIATIONS IN WEIGHTS AND DIMENSIONS

Weight

The weight of any period of pile shall not change greater than 15% above or 5% underneath the nominal thickness weight. Each and every length shall be weighed individually.

Thickness

The minimum walls thickness at any point shall not greater than 12.5% beneath the nominal wall size specified.

Diameter

The outdoors size of steel pipe stacks shall not vary a lot more than ±1% from the size specified.

Length

Length as specified having a tolerance of ±12.

, AND AppearanceFINISH and WORKMANSHIP

The completed pipe piles will be reasonably straight and shall not contain imperfections in these number or of such persona as to render the tubing unsuitable for pipe stacks.

Surface imperfections, the range of which doesn't exceed 25% in the nominal wall surface thickness, shall be permitted. This can be explored by grinding or filing to establish the depth.

Surface imperfections, the depth of which exceeds 25% of the nominal walls thickness shall be thought of flaws. By welding might be permitted when the degree of defect does not exceed 33 , Repair of problems? % from the nominal walls thickness. Ahead of welding the defect shall be absolutely taken away.

CERTIFICATION

Upon request in the purchaser, within the contract or order, a manufacturer’s recognition that the material was tested and manufactured in accordance with this requirements with each other with a report of the chemical substance and tensile tests shall be furnished.

MARKING

Each and every time period of pipe pile shall be legibly marked by stenciling, stamping, or rolling to show : the name of your manufacturer; heating quantity; the type of pipe; the length, excess weight and size and walls thickness; and the specification number as well as the grade.
