Best price of A252 grade 2 steel line pipe

• A252 specification includes three grades (1, 2, and 3), Grade 3 pipe piling material is the most used optio
• Tolerance allowed: OD tolerances at +/-1%, wall thickness +/- 12%. Weight shall be in +15% or -5% of theoretic weight.
• Lengths: As specified SRL, DRL, or fixed length 20 ft or 40 ft and customized.

 

 

The classification of A252 Steel Piling Pipe is into three grades, with each grade exhibiting varying tensile and yield strength. These two

mechanical properties are deemed relevant for pile driving. While the pipe for grade 1 has the lowest yield and tensile strength values, the

mechanical properties of astm a252 grade 3 steel line pipe supersede the other grades. The tensile strength of grade 3 rounds about 456 Mpa

and yield strength valued at 310 Mpa.  A benefit of using these pipes is that they can be tailor-made to suit the specifications of a particular

application, which in turn minimizes the cost. Since the astm a252 grade 2 pipe is durable and sturdy, businesses that use them do not have to

invest in additional capital to secure extra components for structural support. Furthermore, a low cost of their set-up, in conjunction with ease in

installation, make them commercially attractive. The astm a252 steel pipe can be examined and their safety could be tested prior to installation.

 

Material analysis

Heat Analysis: Limits to elements P, and heat result shall be reported in MTC to customer.

Product Analysis: Test frequency shall be determined by the pipe diameter, where, under 14 inch 2 samples per 200 pieces, 14 to 36 inch 2 samples per 100 pieces, above 36 inch is 2 per 3000 ft.

Tensile requirements: Values shall be complied to the above tensile strength and yield strength. It shall be noted that if got a vague yield point, then to test yield strength corresponding to a permanent offset of 0.2% of the gage length of the sample specimen, or to test a total extension of 0.5% of the gage length under load.



 

Weight and dimension tolerances

Pipe pile weights per units (Feet, meter or lengths)
Tolerance allowed: A252 pipe pile weight shall be in +15% or -5% of theoretic weight. OD tolerances at +/-1%, wall thickness +/- 12%.

Lengths: As specified SRL, DRL, or fixed length 20 ft or 40 ft and customized.



 

Different than other pipelines

Hydrostatic test is not specified in ASTM A252 pipe specification, as normally piling pipe is filling with cement and concrete and forming, not for liquid transmission, so hydrotest is not required.


 

Different test methods for seamless and welded pipe piles

Seamless, welded, (Longitudinal or helical welded) test methods are different. Check ASTM A252 pipe standard specification for more details. But all of these types are tested in a room temperature.
