Welcome Kuwait contractor to visit XINYUE STEEL

 Xinyue Steel Pipe is selling well all over the world. In October 2018, our Tianjin Xinyue Steel ushered in a visit by a Kuwaiti contractor and signed a contract.

During this trip, Mr. Mohammad visited our headquarters and factory. The two parties gave a comprehensive introduction and communication to each other at the meeting, which improved mutual understanding of each other. From the production equipment, production process, testing, packaging, inventory, etc, a series of quality control systems are particularly praised and show a strong long-term cooperation interest.

In the case of accreditation of the quality and company strength, we directly cut into the topic to talk about the order, we discussed the price, delivery, payment method, shipping plan, etc., according to the requirements of the guests, we gave multiple solutions. After a thorough negotiation between the two parties, all the concerns of Mr. Mohammed were answered satisfactorily and the order was confirmed directly on site.

Under the full recognition of our company, Mr. Mohammed also offered to purchase all the fitting pipes and also considered to cooperate with our company, and immediately start to visit our fitting pipe factory, Mr. Mohammad get a comprehensive and systematic understanding of the process and equipment of the fitting pipe and quality control.

ERW Pipe vs SMLS Pipe

 Comparison of ERW pipe and seamless pipe (SMLS):

(1) Superior tube blank quality

Compared with the tube blank of SMLS steel pipe, the design of chemical composition of high frequency welded pipe (ERW) is more scientific and reasonable.

ERW special steel grades are characterized by high purity. Through de-S, de-P, degassing, Ca treatment and other methods, the content of S and P can be controlled below 0.005%, the content of N can be controlled below 0.008%, the shape of inclusions can be controlled to be spherical, and the number of inclusions can be greatly reduced . The C content is controlled below 0.1%, so that the welding including the construction process of girth welding has good welding performance, and the increase in strength is to prevent the growth of austenite grains by adding trace alloying elements such as Nb, V, and Ti. At the same time, gap strengthening is increased to improve the toughness and strength of the steel. The tube blank of SMLS steel pipe is generally made of A3, #20 steel, 16Mh and other materials. The purity of the material is poor, and the C content is high, generally around 0.2%, which is not conducive to the girth welding in construction. The strength is acceptable, but Poor toughness.

Another major difference between ERW steel pipe blanks and SMLS steel pipe blanks is that the former is made of hot-rolled steel strips by cold rolling, while the latter is formed by perforating round steel in a hot-rolled state. Obviously, the grain size and the weave density of the SMLS tube blank formed in the hot rolling state are quite different from those of the ERW tube blank, and the properties that can be caused by this must also be very different.

(2) Advantages of geometric size

No matter from the comparison of the data or the comparison of the measured data in the data, the dimensional accuracy of ERW steel pipe is higher than that of SMLS. This is because the seamless pipe is formed by continuous perforation of the round steel in the hot rolling mill, while the ERW steel pipe is formed from the steel strip in the cold rolled state. In contrast, ERW is easier to implement than SMLS in terms of external dimensions. Because of this, the appearance quality of ERW steel pipe has fewer defects, and the appearance quality is also better than that of SMLS steel pipe.

In addition, due to the use of the computer flying saw, the precision of the fixed-length rate and the fixed-length length of the high-frequency welded pipe is high.

Since the high-frequency welded pipe is made of hot-rolled steel strip with high rolling precision, its thickness is easy to control, and the steel pipe with thinner wall thickness and higher steel grade can be produced according to the design requirements. For example, after several repeated demonstrations, the pipes used in the West-East Gas Pipeline Project are basically determined to use X70 steel grade, with a wall thickness of 14.7mm and Ф1016mm. The steel grade is increased, the wall thickness is reduced, and the project investment is relatively reduced, about 5 billion yuan . The wall thickness of seamless pipes is often limited by perforation technology and production costs, and thin-walled steel pipes are very difficult.

Attention to detail for air export

 All countries have strict control the import and export of air transport, and they need to handle various complicated procedures. Air freight forwarding companies need to deal with many details in the process of international air cargo logistics. The following is the experience of several air export exports from Tianjin Xinyue Industrial and Trade Co.,Ltd.

Basic requirements of airlines for the outer packaging of goods

Packaging requirements, the goods cannot exposed, should firm and meet international transport standards. Wooden boxes are best for exporting (such as plywood, mixed boards etc.). It is best not to use wooden boxes made of logs. Many countries have restrictions on logs wooden boxes. Extra large pieces which gross weight is equal to 60KG, must hold in order to use the forklift. The pallet should be flat on the ground.

Determine the quantity of goods

The number of pieces of goods should be guaranteed before the goods arrive at the airport! This is related to the speed of the warehouse and the workload of the airport. The number of items provided by the general cargo owner is not accurate, and the operator can re-implement the exact number of pieces of the goods after the goods are delivered or as soon as possible. Whether the number of pieces is accurate or not affects whether the written air label is valid.

Palletize

The outer packaging of the goods. When booking, you should pay attention to whether the single piece of goods is a large piece of goods. (If the gross weight of a single piece is more than 80KG, you must palletize), or make an appointment with the airport in advance.

Tianjin Xinyue Industrial and Trade Co.,Ltd has rich experience in sea, land and air transportation, providing with the most comprehensive service for you.
