? ?1. Improper Alignment During Material Feeding
The first critical stage where lateral deviation occurs is [^2]**material feeding**. If the steel coil or plate isn’t centered properly before entering the mill, uneven stress distribution will pull the pipe sideways during forming.

Solution? :
– Invest in automated centering systems or laser-guided alignment tools to ensure precise feeding.
– Regular calibration checks on feeding rollers and sensors are conducted.
– Train operators to monitor alignment at the start of each production batch.

—

?2. Uneven Adjustment of Rollers in the Rough Forming Stage
During the **rough forming stage**, lateral deviation often stems from imbalanced pressure on the left and right rollers. If the upper and lower rollers aren’t symmetrically adjusted, the material will deform unevenly, leading to misalignment.

Solution:
– Use hydraulic or servo-controlled [^3]roller systems for real-time pressure adjustments.
– Follow the?supplier’s guidelines for roller gap settings based on material thickness and pipe diameter.
– Implement predictive maintenance to detect roller wear before it causes deviations.

—

3. Loose Edge Bending Rolls in the Fine Forming Stage
The **finishing stage** is where precision matters most. If the edge bending rolls (or “side rolls”) aren’t securely holding the pipe edges, vibration or inconsistent pressure can push the pipe off-center.

Solution:
– Upgrade to adjustable edge rolls with locking mechanisms for stability.
– Optimize the angle and pressure of side rolls based on pipe specifications.
– Install vibration-dampening technology to minimize external disturbances.

What is an expansion anchor pipe?

Expansion anchor pipe is an engineering material. Its main components include a spiral or bolt-shaped tube body. This expansion?system?can form a solid connection with the surrounding soil, rock, or concrete by pressing grout or grouting in the hole after solidification.

What is the usage of expansion anchor pipe?

The design of this pipe makes it suitable for various engineering applications such as foundation reinforcement, tunnel support, geotechnical engineering, and slope stabilization.

1-Foundation reinforcement: By grouting, expanding and solidifying in the soil, anchors can firmly connect the soil, slow down settlement, and improve the bearing capacity of the foundation.

2-Tunnel support: In tunnel construction, expansion anchors support the surrounding rock and prevent rock collapse. Ensure the safe construction and use of tunnels.

3-Rock support: In rock engineering, expansion anchors are used to anchor rocks to prevent rock collapse and landslides. This is particularly common in mines and slope developments.

4-Slope stabilization: Expansion anchors can be used to stabilize earth and rock slopes and prevent landslides and collapses by fixing the soil. This has important implications for protecting the safety of roads, infrastructure, and the surrounding environment.

Aogang has very rich experience with expansion anchor pipe machines, and the new equipment for producing anchor pipes was put into use in northern Russia just last week.

Do you know the difference between friction saw and cold saw?

What is Hot saw?

The Hot/Friction saw uses the thermal friction principle. When the high-speed saw blade (3000 rpm/line speed of 100 m/s) comes into contact with the steel pipe, the intense friction creates a high temperature that fuses the pipe. Burrs will therefore unavoidably form at the end of the pipe.

What is a cold cut saw?

The cold cutting saw is the corresponding name for the Hot/Friction saw

The cold cutting saw’s saw blade’s linear speed is about 120–180 m/min (HSS saw blade). It is known as a “Cold Saw” because it doesn’t create a lot of heat or metal sparks; other names for Cold cutting saws include “Milling saws” and “Burr-Free saws.”

Simply put, the HOT/friction saw is less investment but the pipe end has burrs. The COLD saw is relatively expensive but the pipe end is beautiful and of good quality. We can choose according to our needs.

1. Different shapes: tubes have square, rectangular, and round tubes: pipes are all round.
2. Different toughness: tube is rigid, but also copper and brass; pipe is rigid and resistant to bending;
3. Different classification methods: tube according to outer diameter and wall thickness; pipe according to wall thickness code (pipe schedule and nominal diameter) European standard = national pipe size American standard.
4. The use condition is different: tube is used for small diameter, generally 1/16” to 2” (3mm-50mm) 10-inch tube is rare; pipe is used for large diameter, from 1/8” to 80” All have. 

    

5. The requirements are different: tube pays attention to the accuracy of the outer diameter, because it involves pressure, it is used for cooler tube, heat exchanger tube, boiler tube; pipe pays attention to the wall thickness, because the pipe mainly transports liquid, it requires high internal pressure capacity ;
6. The relationship between the wall thickness grade and the wall thickness is different: the wall thickness grade of the tube is increased by one level, and the wall thickness is increased by 1-2mm, and the increase is fixed; while the wall thickness of the pipe is represented by schedule, and the relationship between the values of each grade is uncertain. For example, the wall thickness of Sch.20 is about 1.245mm, while the wall thickness of Sch.30 is about 1.448mm, and the wall thickness of Sch.40 is indeed 1.727mm, and the increase is inconsistent, because Sch is actually (design pressure/design temperature allowable stress ) X1000
7. The connection methods are different: the tube can be connected quickly, and the connection is not difficult. It can be flared, brazed, or coupled; the connection of the pipe is labor-intensive, and it can be welded or screwed. , you can also use flange connection;

Unqualified steel pipes generally refer to: joint pipes (the steel pipe when the two coils of raw materials are butted), or the welding seam is insufficiently welded, cracked, and the product shape does not meet the standard.

So how to deal with unqualified steel pipes?

Generally in this case, our equipment will pick it out and separate from the finished tube. Our equipment will be equipped with two sets of finished product collection systems, one set to collect finished pipes and one set to collect unqualified steel pipes.

And we will set a long and short ruler cutting on the cutting machine. When encountering the joint pipe, we can press the button of the long ruler or the short ruler according to the specific pipe length, and then we can cut the steel pipe with the joint part. The second cutting is carried out offline, so as to improve the qualified rate of finished products.

Our company will connect the sawing control system with the roller conveyor system and configure a double turning system for customers. The flying saw operator only needs to press the reverse turning button to separate unqualified steel pipes from finished steel pipes and turn them to another product collection device when they are encountered with joint pipes or other conditions. Ensure that the equipment is functioning normally.

The feeding section requires 2 people to cooperate. It is mainly responsible for taking the material from the warehouse with the crane, putting the raw material into the uncoiler or the feeding trolley, and sending the lead to the shearing and welding station manually or by straightning, pinching and leveling; cut the strip head and tail and welded together; then the raw materials are put into the storage Accumulator, and 2 people in this area are mainly responsible for this work.

The forming and sizing machine section requires another 2 people, one of them is an adjustment engineer, who is mainly responsible for the adjustment of the steel pipe from the steel plate to the pipe shape. Generally, this person is also the chief engineer of the whole production line; Another person is responsible for dealing with the outer burrs of the welded pipes, collecting and sorting out the outer burrs, and sometimes the adjustment engineer will also do this job part-time.

1 person is required for high-frequency operation, who is mainly responsible for: high-frequency fire size and speed adjustment.

Flying saw operation requires 1 person, mainly responsible for the pipe length and quantity setting, as well as product quality control.

Stacking machine is divided into manual and automatic. Generally, manual stacking requires at least 3 people. This place is relatively labor-intensive and is mainly responsible for the stacking, bundling and transportation of steel pipes; and if use automatic stacking machine, 2 people is enough, and it can greatly save labor and reduce labor intensity .

If special pipes are made, such as shock absorber pipes, oil cylinder pipes, water gas pipes, and API pipes, more processes are required, and more personnel are required.
