ASTM A312 TP316L Austenitic Stainless Steel Pipe
ASTM A312 / A312M seamless, straight-seam welded, and cold worked
welded austenitic stainless steel pipe intended for
high-temperature and general corrosive service. Several grades of
steel shall conform to the required chemical composition for
carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel,
molybdenum, titanium, columbium, tantalum, nitrogen, vanadium,
copper, cerium, boron, aluminum, and others. All pipes shall be
furnished in the heat-treated condition in accordance with the
required heat treating temperature and cooling/testing
requirements. Tensile properties of the material shall conform to
the prescribed tensile strength and yield strength. The steel pipe
shall undergo mechanical tests such as transverse or longitudinal
tension test and flattening test. Grain size determination and weld
decay tests shall be performed. Each pipe shall also be subjected
to the nondestructive electric test or the hydrostatic test.
ASTM A312 Stainless Pipe Manufacturer
We are professional ASTM A312 stainless Pipe manufacture &
supplier, having capability to produce wide range size steel Pipe
for heat exchanger system, manufacturing process starts from
extrusion of billet, by cold rolling and cold drawn methods to
control size and tolerance, heat treatment will be finished after
cold working to achieve original steel properties, which improve
high temperature resistance and corrosion resistance, then Pipes
should be under pickling passivation condition.

ASTM A312 TP316L Stainless Pipe Lengths
- Unless otherwise agreed upon,all sizes from NPS 1/8 to and
including NPS 8 are available in a length up to 24 ft with the
permitted range of 15 to 24 ft.Short lengths are acceptable and the
number and minimum length shall be agreed upon between the
manufacturer and the purchaser.
- If definite cut lengths are desired,the lengths required shall be
specified in the order.No pipe shall be under the specified length
and no pipe shall be more than /4 in.[6 mm]over the specified
length.
- No jointers are permitted unless otherwise specified.
ASTM A312 TP316L Stainless Pipe Testing Requirement
Each Pipe shall be subjected to the nondestructive electric test or
hydrostatic test, Manufacturer Material Test Certification as per
EN 10204 3.1 should be provided.
- Tensile property, Elogation
- Hardness testing, Brinell, Rockwell, Vickers hardness
- Flattening testing
- Flaring testing
- Hydrostatic or Nondestructive test
- Intergranular Corrosion Test – ASTM A262/E (option)
ASTM A312 TP316L Stainless Pipe Marking
In addition to the marking specified in Specification
A999/A999M,the marking shall include the NPS(nominal pipe size)or
outside diameter and schedule number or average wall thickness,heat
number,and NH when hydrotesting is not performed and ET when
eddy-current testing is performed or UT when ultrasonic testing is
performed.The marking shall also include the manufacturer’s private
identifying mark,the marking requirement,if applicable,and whether
seamless(SML),welded(WLD),or heavily cold-worked (HCW).For Grades
TP316LH, TP316H, TP321H, TP347H, TP348H, and S30815,the marking
shall also include the heat number and heat-treatment lot
identification.If specified in the purchase order,the marking for
pipe larger than NPS 4 shall include the weight.
ASTM A312 TP316L Stainless Pipe Packing
A312 Seamless Pipes is sleeved into plastic bag individually,
pieces wrapped with water-proof material, bundled with nylon rope.
Clear labels are tagged on the outside of the package for easy
identification of the quantity and product I.D. Great care is taken
during operation and transportation.
A312 Steel Seamless Pipes packing will be according to
international standard in bundles strapped by strips then into
containers to avoid any damage. Delivery: Within 10-25 days or asap
if we have enough stock
