About ASTM and our products:
ASTM established in 1898 and it is one of the world’s largest international standards developing organizations. The different standard has a variety of categories which include-
• Standard Specification
• Standard Test Method
• Standard Practice Guide
• Standard Classification
• Terminology Standard
ASTM A 335/ A691 GR P5 Alloy Steel Seamless & EFW Pipes are manufactured with the alloy of ASTM A 335/ A 691 GR P5 alloy. These alloys provide the desired properties and mostly used in many applications. These alloys are covered carbon and alloy steel alloy which includes many things such as electric-fusion-welded, fabricated from pressure- vessel- quality plates, their strength levels are suitable in high-pressure service at high temperatures. Mechanical and chemical properties of these alloys are excellent and fulfill all the requirements of many industries. Silver tubes focus each step of the manufacturing and provide the international standard ASTM A335/ A691 GR P5 Alloy Steel Seamless & EFW Pipes products in the market.
All Pipe is manufactured and inspected/tested to the relevant standards including ASTM, ASME, API.
