What Types of Anchor Bolts are used as Wind Tower Fastener
Most of high-strength anchor bolts for wind power use 10.9 grades, and a few are 8.8 or 12.9 grades. High-strength anchor bolt quality for wind turbines is greatly affected by raw materials.
Why Choose ASTM A193 B7 Round Billet for Anchor Bolt
B7 steel is a high-strength fastener suitable for high-temperature and high-pressure environments in American ASTM A193 / A193M “alloy steel and stainless anchor bolt materials at high temperatures” standard.
Analysation of Self Drilling Rock Bolt Advantage in Application Fields
The drilling depth of self drilling rock bolt should not be less than the effective length of the anchor rod body, overlength of rod body should not be greater than 100mm.
Anchor Bolt Important Role in Wind Turbine Foundation
Anchor Bolt for wind turbine cage foundation is used to attach wind turbine to steel rebar and concrete structure. Anchor cage bolt requires high strength as well as anti-corrosion characteristic.
Rock Bolt Rod Material Heat Treatment
Rock bolt rods are usually made of high-quality alloy steel. The most commonly used materials are medium-carbon alloy structural steels such as 40Cr , 35CrMo and 42CrMo with good hardenability.
Anti-corrosion Methods of Rock Bolt
The hardness of surrounding rock determines its load capacity, if capacity is strong and hardness is sufficient, the maintenance effect naturally becomes better. At the same time, anti-corrosion of rock bolt is very important. which need to be paid with close attension.
Heat treatment Technology in High Strength Anchor Bolt Production
Using highs strength roud bar as raw material, usualy the material is 42crmo, we can get round bar of high strength and better mechanical property with proper heat treatment technology, which Longteng has been used to produce wind turbine foundation bolt for decades
Analysis of High Strength Rock Bolt Application in Mining Fields
High strength rock bolts are a kind of material used in mine support engineering. Its scope of use is very wide, and its advantages and disadvantages are different depending on its arrangement.
Main Failure of High-Strength Anchor Cage Bolts
Fatigue is a form of failure in which high strength anchor cage bolts are cracked or broken under repeated action of cyclic stress and strain.
Right-handed Rock Bolts Introduction
Rock Bolts are generally suitable for reinforcement of mine roadways, bridge tunnels, track slopes, etc. The general rock bolt holes are drilled with a bolt drill, then the appropriate anchoring agent (resin roll) is placed
