Forever hardening and tempering furnace has wide application for oil industry as oil pipe need to do heat treatment before using. And oil pipe such as tubing, casing, drill pipe have strict standard for different grade and pipe type. Forever designed two sets of tubing hardening and tempering line for users.

ø60.3,Ø73.2,Ø88.9,139.7 mm Pipe induction quenching and tempering machine

ø88.9-219 mm Tubing hardening and tempering line

After hardening and tempering with our machines, the tubing performance can meet the API 5CT standard in the tensile strength, yield strength, hardness, elongation and so on.

Process Description for Tubing hardening and tempering line

According to the production requirements, the operator can use crane to lift the steel pipe onto the storage platform, and then arranged pipes in order manually.When every procedure of the line is in good condition, start the frequency transportation roller table in normal rotation state. Manual or automatic start feeding machine to work. Under the control of sensor, the feeding device will lift the pipes on the alignment device and rolled to the roller table with slope angle.

The frequency feeding transportation roller table will input pipes at set speed. The frequency feeding transportation roller table is single roller driving, and the speed and height can be adjusted. The roller type is V type. The transportation roller has slope angle, which can make sure the pipe rotate by itself during pipe transportation. This design is good for pipe uniform heating and avoid pipe bending after quenching. The transportation rollers between and before the inductor is made of austenitic stainless steel. There is circulating water cooling system inside the feeding roller:this can not only cool the roller table but also keep the surface of roller table dry. The other transportation roller table are all made of wear-resistant stainless steel.
