Small diameter ERW of cutting, galvanizing, threading with successfully delivery

 Tianjin Xinyue received the customer's inquiry at the end of February. At the beginning, the customer required to make seamless steel pipe. After several communication, the customer finally decided to make straight welded pipe instead of seamless steel pipe. It’s fix length 3.05 meters, surface galvanized and tube ends was threaded. The thickness of galvanized is 45 microns. This steel tube is the first trial order of the customer for installing lamps.

Straight seam welded pipe surface do galvanized tube and steel tube should be cut into 3.05 meters in length, the customer request strictly, in order to better control the length tolerance, need to cut pipe a a cut, but this will increase the processing cost, in order to meet the needs of customers and orders requirements, tianjin xinyue would like to reduce profits, to ensure that meet customer's technical requirements, so as to achieve the long-term friendly relations of cooperation.

How to Prevent Surface Decarburization of Seamless Pipe Products?

 The carbon element in the seamless steel tube (smls) has a great influence on its own performance, so when the seamless tube is decarburized, its service life will be greatly reduced, and if the surface of the seamless tube is decarburized If it is not cleaned, the hardness and wear resistance of the surface layer of the seamless pipe will be reduced, and during quenching, cracks will be formed on the surface of the workpiece due to the different volume changes of the inner and outer layers. Therefore, how to prevent the surface decarburization of seamless pipes is a problem that should be paid attention to in the production process.

The key to solving the problem of surface decarburization lies in the heat treatment process. Since the decarburization and the oxidation of the steel wire are carried out at the same time, the purpose of improving decarburization can be achieved as long as the non-tin seamless pipe is kept in contact with air as little as possible during the heat treatment process. The production process is: the first molten lead tank is used to austenitize the steel wire. The lead liquid is heated to 871? in advance, the steel wire is passed in the lead liquid to achieve austenitization, and then enters the oil tank for quenching, and then enters the second Two molten lead tanks are tempered (482°C). Since the steel wire is not in contact with air in the molten lead, decarburization is effectively avoided. The main problem that needs to be solved with this process is how to prevent lead dust pollution.

The atmosphere that causes decarburization on the surface of seamless pipes is mainly oxidizing gases such as oxygen, water vapor, and carbon dioxide. When these oxidizing gases contact the surface of the heated steel wire, oxidation and decarburization occur simultaneously; because the solid-solution carbon in the iron has a relatively large affinity for these gases, the carbon on the surface is removed first. The above-mentioned gases are generally brought in from outside the furnace; the iron oxide scale, rust on the surface of the seamless pipe and the residues on the surface of the steel wire after cold drawing will also decompose after being heated in the furnace and react to generate some oxidizing gases. We can purposely control the atmosphere in the furnace to make it in a reducing state, which can effectively avoid surface decarburization. For example, controlling the ratio of carbon dioxide to carbon monoxide in the furnace, at the equilibrium point, neither oxidation nor decarburization; when the ratio of carbon dioxide exceeds the equilibrium point, oxidation and decarburization will occur; when the ratio is below the equilibrium point, oxidation and decarburization will not occur . The specific value of the equilibrium point should be calculated based on the carbon content and temperature of the iron.

In addition, it is also an effective measure to inject neutral protective nitrogen into the furnace from the seamless tube. At the same time, it can maintain the positive pressure in the furnace, prevent air infiltration, and reduce or avoid decarburization of steel parts.

Xinyue Has a Constant Supply Steel Pipe to Nigrian Projects

 In recent years, Tianjin Xinyue Steel Group has established friendly relations with Southeast Asia, South America, European countries. Oil and gas projects in African countries are also on the rise, with Nigerian customers increasingly taking orders.

In February 2020, Tianjin Xinyue Steel group again received inquiries from regular customers in Nigeria. This time, the inquiry is still the same as the last order of seamless tubes, the specifications from 1 inch to 12 inches, a total of more than 2,000 pieces. Due to the experience of last year's transaction, both parties soon reached an agreement on both price and payment terms. At the same time, the customer inquired for 200 tons of ERW tube. After 2-3 days' communication, the customer finally placed the two orders together to Xinyue Steel Group.

Tianjin Xinyue Steel Group began to resume work in early March, the first time to arrange the production department for production. After a month and a half, the production of the order was completed in the middle of April as scheduled and is now waiting for shipment at the port of Tianjin.

No matter what large or small of the order and the complexity of the product, as long as we can help customers to solve the problem, Xinyue Steel Group team will serve customers with a professional attitude.

Seamless Steel Tubes And Pipe Fittings To South Africa Passed TPI Inspection

 By the end of May 2020, seamless steel pipes and fittings to South Africa had completed various inspections and were waiting for shipment to South Africa. The transaction of these seamless tubes and fittings stems from the trust and recognition of Xinyue's product quality after customers first cooperated with Xinyue last year.

In July 2019, when the steel market in China was in full swing, we signed our first contract with a new customer in South Africa, and started production soon. After more than a month of production, on the afternoon of August 15th, we received a notice from the customer: August 16th, that is, the next day they will fly to China. Head for on-site inspection and inspection. Although it was a "surprise inspection" of the customer, all the test results passed smoothly.

Meanwhile, we have received a precious praise from our customer:

“ Sorry that we came to visit you in a such hurry schedule, but what you showed me, your work efficiency, really impressed me. We have worked on steel industry for many years, and have seen a lot of factories before, but you Xinyue team is the only one who can give me an comprehensive solution within 20 minutes. I feel really happy to work with you, to work with Xinyue. ”

Based on the first pleasant cooperation, the customer received the goods in September?2019, and after the end customer passed the acceptance, he immediately sent us an inquiry for the second phase of the project. After half a year of bidding process and our full support to customers in the bidding process. In March this year, the customer successfully won the bid, and the second phase of the project customer also gave this order to us. Due to the global epidemic situation, the customer could not come to the factory to inspect the goods in person, so a third-party testing agency was invited to conduct the process inspection.

For such strict three-party testing, it is a common sight in our production. In the past 8 years of export history, we have encountered many process inspections and final inspections from different customers. Each inspection, the customer is very satisfied. During the production process, factory quality inspectors and tripartite inspectors separately conducted all pipe and pipe sample: impact test, tensile test, bending test, elongation test, hardness test and chemical composition test, etc.

The customer has confirmed the tripartite inspection report so far. We will catch up with the bulk carrier at the end of the month and send the shipment to South Africa. This cooperation will undoubtedly give customers a better understanding of Xinyue's quality. We look forward to the next cooperation.

Causes of Defects in Hot rolled Seamless Steel Pipes

 Hot-rolled seamless steel pipe is a round, square, and rectangular steel with a hollow section and no joints on the periphery. When the bending and torsion strength is the same, the weight is lighter. It is an economical cross-section steel. What defects are prone to appear in the production process of steel pipes? Let’s explain it for everyone.

1) Cracks (also known as cracks). Features: The inner and outer surfaces of seamless steel pipes are linear or spiral cracks, and some are mesh-shaped and both ends and bottom of the cracks are sharp.

1. Poor steel quality, with subcutaneous pores and subcutaneous inclusions.

2. Improper heating of the tube billet.

3. The deformation pressure is too large.

2) Hairline, features: continuous or discontinuous hair-like fine lines appear on the outer surface of the seamless steel pipe. Most of the spiral spiral direction is opposite to the direction of rotation of the punch, with a large pitch, and some are similar to a straight line.

1. Poor steel, with subcutaneous pores and subcutaneous inclusions.

2. The surface of the tube blank is incompletely cleaned.

3) Inward fold (commonly known as inner fold), features: straight or spiral zigzag defects on the inner surface of the steel pipe. For high-alloy steel pipes, such defects are irregular blocks and distributed at the entrance. If the fold is caused by centering, it is usually half a circle to a circle, and it is on the head.

1. The amount of pressing down the front of the head is too large.

2. Serious head wear.

3. During the piercing process, the metal in the central part of the blank bears strong alternating stress, so the inner wall of the waste tube is prone to inward bending during rolling.

4. The inward folding at the entrance of the high-alloy steel pipe is caused by uneven force on the roll during piercing.

4) Outer folding, characteristic: the outer surface of the seamless steel pipe is spirally folded, and the spiral direction is opposite to the spiral direction of the waste pipe on the punching machine, and the pitch is relatively large.

1. Defects such as cracks or ears remain on the surface of the tube blank.

2. Poor steel quality, inclusions or serious looseness.

5) Rolling and folding, characteristics: there are regular folding defects on the outer surface of the seamless steel pipe.

It is mainly caused by damage to the roll of the piercing machine or the roll of the tube mill.

6) Bending, characteristics: during rolling, the metal enters the gap between the rolls or the tube loses its stability, causing it to form twists and turns. After sizing, the surface of the steel tube shows local convex and concave wrinkles.

1. The outlet pipe diameter of the equalizing machine is larger than the hole type of the fixed and reducing machine.

2. Incorrect adjustment, misalignment of rolls, inconsistent center lines, etc.

3. The sizing frame is installed upside down.

7) Straight inward folding. Features: The inner surface of the seamless steel pipe is symmetrical or a single straight line folding, distributed over the entire length or part of the steel pipe.

1. The head is severely worn or stuck to metal.

2. The outer diameter of the capillary tube is larger than the width of the grooved hole, the inner diameter is too large or the tube wall is too thin.

3. Unreasonable distribution of reduction of piercing machine and tube rolling machine.

4. Before the second pass of rolling, the 90° overturning was not completed.
