Riyaarth overseas is a leading manufacturer, suppliers, exporter of Alloy steel pipes in SOUTH KOREA . Alloy steel pipes are a type of steel that is alloyed with various elements, such as chromium, molybdenum, manganese, nickel, and vanadium. This combination of metals creates a strong material which is ideal for use in various industrial applications.

The most common type of Alloy Steel Pipe is seamless pipe. Alloy Steel seamless Pipe is made by extruding a heated block of metal through a die and then cutting it to length. Seamless pipes are used in high-pressure applications because it can withstand greater forces than other types. Seamless pipe also come in several wall thicknesses so that different levels of pressure can be handled.  
Another type of Alloy Steel Pipe is Welded Pipe. Welded Pipe are made by welding two pieces of metal together. Welded pipes are mostly used in low-pressure applications where there is not much stress on the material as there would be with a seamless pipe.

Our clientele spans across diverse industries, including petrochemical and chemical sectors, oil refineries, nuclear power plants, power generation facilities, chemical fertilizer manufacturers, and oil mills, among others. This demonstrates the versatility and utility of our ASTM A335 alloy steel pipes and tubes in critical applications.

This ensures that our clients have full access to the relevant product information and compliance details.

With our extensive product range, focus on quality, and dedication to customer needs, Riyaarth Overseas has earned a strong reputation as a preferred supplier of ASTM A335 alloy steel pipes and tubes, both domestically and globally.

ASTM A335 is the standard specification for seamless alloy steel pipe for high temperature service. It covers sever grades: P1, P2, P5, P5b, P5c, P9, P11, P12, P15, P21, P22, P23, P91, P92, P122, out of which P5, P9, P11, P22, P91, and P92 are most widely utilized in practice. The specification covers nominal wall and minimum wall chrome-molybdenum( also known as Cr-Mo, or Cr-Moly) alloy steel pipe intended for high-temperature application. Pipe ordered to this specification shall be suitable for bending, flanging(vanstoning), and similar forming operations, and for fusion welding. ASTM A335 P11, P22, P91 and P92 are commonly used in power plants and chemical-petrochemical industry, while P9 and P5 are mainly used in petroleum refineries. Hebei Metals supplies ASTM A335 Cr-Mo alloy steel seamless pipes sized from 1/2″ to 24″(NPS15 ~ NPS600) ranging in wall thickness from SCH20 to XXS or even thicker.

Heat Treatment and Delivery Conditions of ASTM A335 Alloy Steel Pipes/ ASTM A213 Alloy Steel Tubes

ASTM A335 pipes may be either hot finished or cold drawn with finishing treatment listed below:

1. Pipes of all grades of ASTM A335 except P5c, P23, P91, P92, P122, and P911 shall be reheated, and furnished in the full-annealed, isothermal annealed, or normalized and tempered condition, the minimum tempering temperature  for grades P5, P5b, P9, P21, and P22 shall be 1250°F (675°C), the minimum tempering temperature for grades P1, P2, P11, P12, and P15 shall be 1200°F (650°C). It is recommended that the temperature for tempering should be at least 100°F (50°C) above the intended service temperature; consequently, the purchaser should advise the manufacturer if the service temperature is to be over 1100°F (600°C).
2. ASTM A335 Pipe of Grades P1, P2, and P12, either hot finished or cold drawn, may be given a final heat treatment at 1200°F (650°C) to 1300°F (705°C) instead of heat treatments above-mentioned.
3. Pipe of grade P5c shall be given a final heat treatment in the range from 1325°F (715°C) to 1375°F (745°C).
4. ASTM A335 grades P92 & P911 shall be normalized at 1900°F (1040°C) minimum and tempered at 1350°F (730°C) minimum as a final heat treatment.
5. Grade P122 shall be normalized at 1900°F (1040°C) minimum, and tempered at 1350°F (730°C) minimum as a final heat treatment.
6. Grade P23 shall be normalized at 1900°F (1040°C) minimum with air cooling or accelerated cooling and tempered at 1350°F (730°C) minimum as a final heat treatment.
7. ASTM A335 P91 shall be normalized at 1900°F (1040°C) minimum, and tempered at 1350°F (730°C) minimum as a final heat treatment. Alternatively, liquid quenching and tempering is allowed for thicknesses above 3 inch when mutually agreed upon between the manufacturer and the purchaser. In this case the pipe shall be quenched from 1900°F (1040°C) minimum and tempered at 1350°F (730°C) minimum as final heat treatment.

Tests and Examinations of ASTM A335 Alloy Steel Pipes/ ASTM A213 Alloy Steel Tubes

1. Unless an alternative nondestructive electric test is selected or otherwise specified by the purchaser, hydrostatic test shall be performed for each length of ASTM A335 pipe.
2. Mechanical Tests: pipes of all grades of ASTM A335 shall take transverse or longitudinal tension test and flattening test, hardness test, or bend test. The test will be made on 5% of the pipe from each heat number.
3. The nondestructive test (NDT) shall be performed in accordance with Practice E 213, Practice E 309, or Practice E 570. These NDT methods includes: Ultrasonic Examination, which shall be performed to detect both longitudinally and transversely oriented discontinuities; Eddy Current Examination, which has the capability to detect significant discontinuities especially of short abrupt type; Flux Leakage Examination, which is capable of detecting the presence and location of significant longitudinally and transversely oriented discontinuities.
