ERW and Seamless steel pipe from Xinyue Steel to Australia

 This is an Australian customer. Since we met, we have successfully completed 10 orders, and the epidemic didn’t stop the pace of cooperation between the two sides. The customer is engaged in the equipment manufacturing industry and attaches great importance to product quality. In the process of order service, from the early cooperation until now, he has become a loyal customer of Xinyue. Because Xinyue has always put product quality first, we firmly believe that this is the cornerstone of enterprise development, and only by creating high-quality products can we be invincible.

Project location：Australia

Product：ERW Steel Pipe and Seamless Steel Pipe

Standard and material：API 5LGR.B

Specifications：4″, 8″, 12″

Application：Pressure Pipeline

Inquiry time：2022.07.06

Order time：2022.07.25

Shipping time：2022.09.03

Arrival time：2022.10.08

In July 2022, the customer placed the order to our company again. For this batch of steel pipes, the customer needs to process the internal threads later, so we need to control the inner diameter of the steel pipes. During the re-inspection of finished products, our quality inspectors recheck the inner diameters of steel pipes one by one to ensure that the inner diameters of each steel pipe meet the processing requirements. Before the shipment, the third-party testing company designated by the customer has carried out the final inspection of the goods, which is up to expectations. All the testing data meet the customer’s requirements. At present, all goods have been put into use and highly praised by customers!

In fact, for Australian customers, Xinyue has many years of successful experience and has already formed its own professional operation process. It will prepare some document templates, packaging statements, Chinese and Australian certificates of origin, etc. in advance for later use. Such a series of operations will help customers to enjoy relevant preferences in customs clearance at the port of destination and provide the best service for customers.

Common questions refers to resistance welding

 Resistance welding is a method of combining the workpieces and applying pressure through the electrodes, using the resistance heat generated by the current passing through the contact surface of the joint and the adjacent area for welding. Resistance welding is a method in which electric current flows through the contact surface of the workpiece and the resistance heating effect generated in the adjacent area to heat it to a molten or plastic state to form a metal bond. ERW steel pipe is a steel pipe rolled using the electric resistance welding process.

Common welding problems and causes of resistance welding

1. Splash

If the heating is too rapid, and the surrounding plastic ring has not yet formed or is not tight enough, the sharply heated contact point will rise extremely fast due to the temperature. The internal metal is vaporized, and under the action of the electrode pressure, the liquid metal in the ring will be pressed out, and then sprayed to the gap between the plates in the form of splash, which is called the reason for the internal splash:

1) The surface of weldments and electrodes is not clean and there is a lot of dirt;

2) Electrode pressure is too small

3) The weldment and the electrode are not in real contact

4) Iron particles stick to the surface of the electrode

5) The assembly gap is too large, and the two contact surfaces of the workpiece are uneven

6) The workpiece is not clean

7) The shape of the electrode contact surface is not correct

8) The preloading time is too short

9) Excessive current

10) The workpiece is placed unevenly and inclined during welding

11) Small margins.

After the minimum nugget is formed, continue to heat, and the nugget and plastic ring continue to expand outward. When the expansion speed of the nugget in the radial direction is greater than the expansion speed of the plastic ring, it will fly out. The reasons for this are:

1) The welding current is too large;

2) The welding time is too long.

It is caused by the strong electrode pressure breaking the plastic ring around the point core and causing the overflow of liquid metal.

2. Weak soldering

Causes:

1) The voltage is too low, and the magnetic material enters the secondary circuit of the welding machine;

2) The dot pitch is too small;

3) The current is small and the electrode pressure is large;

4) The diameter of the electrode end face is large;

5) Electrode surface wear and stacking;

6) The welding time is insufficient, and the welding specification is too strong.

3. Solder punch through

Causes:

1) The current is too large;

2) Insufficient electrode pressure;

3) The power-on time is too long;

4) Poor electrode cooling conditions;

5) The heating time is too fast

4. Solder joint indentation depth

Causes:

1) The power-on time is too long;

2) Insufficient electrode pressure;

3) The current is too large;

4) The solder joint is seriously overheated;

5) Severe spraying;

6) The original size of the welding and assembly room;

7) The electrode is too sharp (the diameter of the electrode end face is too small)

The electrode indentation depth on the surface of normal solder joints should not exceed 10%-20% of the plate thickness

This order is not easy for us and customer. The end user has strict requirements on the steel grade of the steel pipe, and the wall thickness is 20-75mm. Regular customer contacted Xinyue at the first time when they received the project. Many successful cooperation cases in the past make them feel that Xinyue is a very trustworthy partner. Whether resources or professionalism, Xinyue hand this project will give them incomparable confidence. we began to prepare the best scheme when we received the inquiry. However, due to repeated changes in the design, we were unable to confirm the order, but we updated the feasible scheme for the customer many times during the process to support.

Until the end of May, the end user confirmed the final design, customer signed a contract with Xinyue immediately. After the gap of four months to confirm the design, the previous inventory pipes had been sold out. In order to support the customer to complete the project as soon as possible,our company gathered support from multiple departments. The procurement department integrated all resources to find the suitable raw material steel plate for this production. The production department mobilized excellent technical workers to work overtime to put it into production, The document Department handled the freight forwarding procedures and shipping matters in time, while the quality inspection department strictly carried out every test step during the production process, First step carried out physical, chemical and impact tests on the raw steel plate (CNAS laboratory), and then tested the physical and chemical and impact properties of the finished steel pipe and 100% NDT test on the weld area of T-shaped welded pipe, to ensure the quality of all pipes. Through the cooperation of all departments, the delivery date was finally controlled within 40 days. At present, the products have been delivered and put into project production. Wish our customer a better business.
