45# Large Caliber Thick Wall Seamless Pipe

Big Diameter Honed TubeBrief introduction: No. 45 thick wall seamless steel pipe is slightly stronger than steel No. 15, seldom quenched and has no temper brittleness. Cold plastic deformation and for bending, rolling, bending and hammer arch processing, arc welding and contact welding welding...

Big Diameter Honed TubeBrief introduction: 
No. 45 thick wall seamless steel pipe is slightly stronger than steel No. 15, seldom quenched and has no temper brittleness. Cold plastic deformation and for bending, rolling, bending and hammer arch processing, arc welding and contact welding welding performance is good, when the thickness is small, prone to strict requirement of shape crack or complex shape parts. The cold or normalizing condition of cutting is better than that of annealing. It is generally used to make the material with little force and high toughness.


45# Large Diameter Seamless tubes information:
No. 45 thick wall seamless steel pipe is slightly stronger than steel No. 15, seldom quenched and has no temper brittleness. Cold plastic deformation and for bending, rolling, bending and hammer arch processing, arc welding and contact welding welding performance is good, when the thickness is small, prone to strict requirement of shape crack or complex shape parts. The cold or normalizing condition of cutting is better than that of annealing. It is generally used to make the material with little force and high toughness. Heat treatment: not less than 156HB, sample size: sample size 25mm. The manufacturing process for the production of No. 45 thick walled seamless steel pipe can be divided into four basic modes of cold drawing, cold-rolled, hot-rolled steel pipe, thermal expansion, the material is 10#, 20#, 35#, 45# called 16Mn between ordinary ordinary steel, steel or alloy steel pipe between called low alloy steel pipe, steel pipe is made of 27SiMn, 12Cr1MoV 15CrMo, 35CrMo, 10CrMo910, and stainless steel tube called alloy steel pipe. According to the application is divided into structure with seamless steel tube for conveying; seamless steel tube; seamless steel pipe seamless steel pipe with high pressure boiler; boiler; high pressure seamless steel pipe seamless steel pipe used for chemical fertilizer equipment; geological exploration bricks; seamless steel pipe for petroleum exploration brick; seamless steel pipe seamless steel pipe used for petroleum cracking; ship; cold rolled precision seamless steel tubes; various alloy tube.

No. 45 thick walled seamless steel pipe is delivered without heat treatment or heat treatment (annealing, normalizing or high temperature tempering). Deliveries requiring heat treatment shall be noted in the contract and delivered without heat.


45#Thick wall seamless pipe Weight formula:
Weight calculation formula of No. 45 thick wall seamless steel tube [[outer wall thickness] * wall thickness]*0.02466=kg/ meters (per meter weight)
