Meeting With Middle Eastern Customers Again After Four Years

 It is always remember the special memory of my first customer. In 2014, we would follow the normal business process like quoting , sending samples, confirming the contract, checking the goods, and delivering to the customer.

Because of the first cooperation, the customer decided to inspection that the goods before loading. , A group of 3 peoples, They were very careful measurement and taking photos, Finally, customer recognized the service and quality of Xinyue and successfully sent the goods away.

Following four years, the customer did not come to China considering to our trust and recognition. Unluckily, When I cooperated for 2 years, there was a very regrettable thing to occur, Mr. Vinod, my dear friends, who went away suddenly. I wouldn’t accept this fact when I receive the email. In fact, a week ago we were still chatting the interesting things of their travels on the WhatAPP.

Another colleague, who we met in 2014, took over his job. They opened up their gas market. We provided product service support. And the annual small diameter seamless pipe orders for gas transfer grew steadily.

When we picked up customers , we looks like old friends, talking about the documents provided by the collection, the market needs to grow, their company continues to expand the market, in addition to diverge neighboring countries beside local market. ,It is expected to have a procurement plan in January 2018, And Hope to offer him the best Service and support as before.

We are serious about steel pipes business. We treat our friends with sincerity also. Build the world getting better and Serve for the global market. Warmly welcome to send Inquiry to Tianjin Xinyue Steel at any time.

Israel steel plate project procurement pre-inspection

 Last week, Tianjin Xinyue Group ushered in a four-person inspection tour of an Israeli customer. Accompanied by our sales department and the factory technical department, the pre-purchase inspection of the Israeli construction steel plate project was carried out. The technical requirements of the project for steel plates are extremely high. This inspection also greatly promotes the development of good cooperation between Xinyue, steel mills and contractors.

During the entire inspection period, the customer first looked at the rolling mill line and had an understanding of the equipment and production process. Due to the customer's neatness and flatness of the steel plate, the requirements are very high. Then we took the customers to visit the shot blast line and the painting line. For the project, the technical parameters of the steel plate are confirmed by the customer and the technician and production manager of the factory. And witnessed the laboratory's experimental process and report. For the questions raised by the customers, the mill technology and Xinyue also carried out professional answers.

Finally, the customer gave a high evaluation of the strength of the steel mill, and said that after returning to Israel, They will decide to purchase the demand soon, hoping that we can give the best price. I believe that as long as we are committed to the best of our services, and always adhere to the "integrity-based, customer first, high quality and efficient" concept, customers will know in the communication and cooperation is a trustworthy partner.

Precautions for welding of tunnel steel support

 Weeds and shrubs are the main areas within the scope of tunnel site selection. During the field survey, the factors affecting the overall stability of the tunnel should not appear and occur. The selection of tunnel steel supports is also very particular, and there are also some principles that need to be paid attention to in welding construction operations.

There are several points to pay attention to when welding tunnel steel supports:

1. In the cold winter, if the steel plate is more than 9mm, it can be welded in several layers. This is to prevent the temperature from being too low, but in general, welding should be completed at one time and continuously. When welding, the defects left by the welding should be cleared first, and the welding can be continued after there is no problem.

2. In such a low temperature environment, the electrodes and wires used for welding steel supports should be low-hydrogen electrodes with low yield strength and good impact toughness under standard conditions.

3. The welding rods used for welding below zero degrees must be of formal standards, which need to be placed in a baking box of 80 to 100 degrees Celsius, and used when needed. If the electrode has been placed below zero for more than two hours, it needs to be re-baked, but the number of times should be less than three times.

4. In the open air environment, the welded steel support can build a shed just in case. Be careful not to get rain and snow on the weld.

Ultrasonic testing of seamless steel tube

 Principle of ultrasonic flaw detection of seamless steel pipe (smls):

Seamless steel pipe is a steel pipe that is perforated from a whole round steel and has no welds on the surface. Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemicals, boiler pipes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation.

The ultrasonic probe can realize the mutual conversion between electric energy and sound energy, and the physical characteristics of ultrasonic waves when they propagate in elastic media are the basis of the principle of ultrasonic flaw detection of seamless steel pipes. The directionally emitted ultrasonic beam encounters defects when propagating in the tube, causing both wave reflection and wave attenuation. After the signal processing of the flaw detector, if the reflection method is used for flaw detection, the defect echo signal can be obtained, and if the penetration method is used for flaw detection, the defect signal can be obtained by the attenuation of the transmitted wave. Both can give quantitative defect indications by the instrument. Different types of ultrasonic waves can be excited in the tube using the piezoelectric effect or the principle of electromagnetic induction. Therefore, both piezoelectric ultrasound and electromagnetic ultrasound can be used for ultrasonic inspection of pipes. But electromagnetic ultrasound is only suitable for ferromagnetic materials.

Ultrasonic flaw detection method of seamless steel pipe:

1. The shear wave (or plate wave) reflection method (or penetration method) is used for automatic inspection in the state of relative movement of the probe and the seamless steel pipe. Only special large-diameter seamless steel pipes can be manually inspected. Automatic or manual inspection shall ensure that the sound beam scans the entire surface of the pipe.

Note: During the automatic inspection, the two ends of the seamless steel pipe will not be effectively inspected, but this area should be controlled within 200mm.

2. When inspecting longitudinal defects, the sound beam propagates in the circumferential direction in the tube wall: when inspecting transverse defects, the sound beam propagates in the tube wall along the direction of the tube axis.

Inspections for and transverse flaws shall be carried out in two opposite directions of the pipe.

3. When the purchaser does not propose to inspect the transverse defects, the supplier only inspects the longitudinal defects. After negotiation and agreement between the supplier and the buyer, the inspection of vertical and horizontal defects shall be carried out.

Can only be done in one direction of the tube.

4. In automatic or manual inspection, the coupling medium with good coupling effect and no damage to the surface of the seamless steel pipe should be selected.

Suspicious seamless steel pipes can be handled by any of the following methods:

1. Carry out repeated flaw detection inspection according to the method specified in this standard. If there is no defect signal or the signal amplitude is lower than the preset alarm level, this inspection is considered to be qualified.

2. Carry out other non-destructive inspections on suspicious parts according to the methods and acceptance criteria agreed upon by both parties.

3. After the visible defects of the suspicious parts are removed, if the size of the seamless steel pipe is within the allowable tolerance range, the pipe shall be in accordance with the method specified in this standard.

method to re-detection inspection. If no defect signal is generated or the signal amplitude is lower than the preset alarm level, this inspection is considered to be qualified.

4. Excision of all suspicious sites.

5. Suspicious seamless steel pipes are rated as unqualified for this inspection.
