Tianjin xinyue steel group will, as always, make our efforts for the construction of the world and ensure to delivery high-quality...

 The anti-corrosion operation we first discuss refers to the routine maintenance of spiral steel pipes that have not been treated with anti-corrosion treatment. Because of its good anti-corrosion performance, the anti-corrosion spiral steel pipe is relatively less affected by the season, but for conventional spiral steel pipes (SSAW) , summer is a season that is easy to be corroded. In summer, the humidity in the atmosphere increases, coupled with the increase in rainy weather, many coiled pipes are stored outdoors, resulting in frequent exposure to wind, rain and scorching sun. If the spiral steel pipe needs to be stored for a long time, a part of the oily substance can be sprayed on the surface to isolate the oxide layer. Try to avoid placing the spiral tube in a low-lying place, which will cause excessive moisture and aggravate oxidation. Other anti-corrosion methods using steel pipes are often referred to as anti-corrosion spiral steel pipes. This processing method refers to co...

 Tianjin Xinyue Steel Pipe is sold all over the world, making a strong contribution to the world's infrastructure, bridges, offshore construction and oil pipeline transportation. And steel pipe export can not be separated from shipping, can not be separated from FOB trade, now give you a general idea of what FOB terms. 1.FOB Liner Terms This distortion means that the cost of shipment is handled in accordance with the liner's practice, i.e. it is borne by the ship or the buyer. Therefore, with this deformation, the seller will not bear the costs associated with shipment. 2. FOB Under Tackle The seller shall bear the cost of delivering the goods to the place where the hook of the vessel designated by the buyer can reach, and the buyer shall bear the cost of hoisting into the hold and other expenses. 3. FOB Stowed It means that the seller is responsible for loading the goods into the hold and for the cost of loading, including the handling fee. Cargo handling fee refers to the cos...

This is the project list of pile pipe for an Australian customer. The customer requires AS 3678 GR350 material, the welding standard is AS 1554.1, and the steel pipe standard is AS1163. The customer is very satisfied with our quality and delivery date because he visited our factory last time. In fact, we have very good control over the delivery date and quality.Below are the photos of our finished steel pipes: The customer and the third party are very serious about the inspection, but our tianjin xinyue products can withstand the verification and inspection, finally the customer and the third party company are very recognized the quality of our products, all the thumbs up. The release slip will be sent to us next Monday.Then we can arrange the delivery. Hope more and more customers use our products and trust our brand.Let the steel pipe products of xinyue build the world and serve the whole world. http://www.tjxysteel.com/news/Australian-pile-project-inspection-for-shipment-805.html

 In the beginning of 2019, A team of professional engineers have come to stay in our mill to do the inspection during production, the products under inspection is SSAW - spiral welded pipes, the main usage is for port construction. The engineers first issued overall mechanical and chemical tests for all finished pipes and, meantime, to launch new tests for the new coming raw material. During that time, Tianjin Xinyue Steel Group accompany the client and give full support on 100% tests for engineer, the test result is good and 100% reach client’s request. As to these pipes, they all have high coating requirements, the rust removal must reach standard of S.A 2.5, under two engineers’ witness, Xinyue Steel totally conform to the standard, and the result has won client’s content. Warmly welcome all clients bring high request on our quality and company, through the high standard, Xinyue Steel Group will make progress on the quality and also management so that we can serve our clients be...

 The surface quenching and tempering heat treatment of seamless steel pipes is usually carried out by induction heating or flame heating. The main technical parameters are surface hardness, local hardness and effective hardened layer depth. Vickers hardness tester can be used for hardness testing, Rockwell hardness tester or surface Rockwell hardness tester can also be used. The selection of the test force (scale) is related to the depth of the effective hardened layer and the surface hardness of the seamless steel pipe. There are three durometers involved here. 1. Vickers hardness tester is an important means to test the surface hardness of heat-treated seamless steel pipes. It can use a test force of 0.5-100kg to test the surface hardened layer as thin as 0.05mm thick. It has the highest accuracy and can distinguish the heat treatment. Small differences in surface hardness of seamless steel pipes. In addition, the depth of the effective hardened layer is also detected by a Vicker...

 The reasons for the deformation of carbon seamless steel pipes are often complicated, but as long as we master the laws of deformation, analyze the causes, and use different methods to prevent the deformation of the mold, it can be reduced and controlled. In general, the heat treatment deformation of seamless steel pipes can be prevented by the following methods. (1) Reasonable selection of materials. For seamless steel pipes, micro-deformation die steels (such as air-quenched steels) with good quality should be selected, and die steels with serious carbide segregation should be reasonably forged and quenched and tempered. Refinement heat treatment. (2) The design of the mold structure should be reasonable, the thickness of the seamless steel pipe should not be too large, and the shape should be symmetrical. For the mold with large deformation, the deformation law should be mastered, and the machining allowance should be reserved. For large and seamless steel pipes, a combined str...
