Trust build cooperation bridges, service forge cooperation ties

The products required in this order were stainless steel rectangular tubes, which were ordered by regular customers in Thailand for deep-processing structural engineering. Customers purchase stainless steel rectangular tubes from Xinyue every year for similar projects. Our company received the customer inquiry in August, then Xinyue made a detailed quotation, covering the cutting scheme and transportation scheme, in combination with the inventory at first time. Compared with the previous purchase price, the customer said that the quotation had increased and asked about the reasons, Xinyue explained to the customer. One reason was the tax rebate, another reason was the sharp rise in the price of raw materials caused by the epidemic. At same time, Xinyue made an in-depth analysis on the trend of steel price in the future. After listening to our suggestions, the customer understood and decided to increase the purchase quantity to avoid another rise in price in the future. The long-term cooperation has built a bridge of trust. The customer confirmed the purchase intention in the shortest time and immediately prepaid the deposit. Our company also entered the preparation period quickly.

Xinyue’s existing inventory of stainless steel square rectangular tubes was sufficient to meet the needs of this order. It only needs to cut into the length and size required by customers. Considering the recent shortage of shipping, the logistics department booked the earliest shipping space to save customers time. Xinyue worked overtime to complete the cutting step, submitted the inspection report to the customer at first time, and quickly sent products to Tianjin port after confirmation. Based on the successful experience of previous orders, the cooperation with this customer was particularly smooth, and all steps were seamlessly connected. From order placement to product delivery, Xinyue completed all operations of the order in less than 10 days. The products arrived in Thailand in mid October and had put into project construction.

Forming control of welded pipe

1. Weld gap control of welded steel tube

The strip steel is sent to the welded pipe unit, rolled by multiple rollers, and the strip steel is gradually rolled up to form a round tube blank with an opening gap. Adjust the reduction of the extrusion rollfer to control the gap between the welds at 1~3mm, and make both ends of the welds flush. If the gap is too large, the proximity effect will be reduced, the heat of the eddy current will be insufficient, and the intergranular bonding of the weld will be poor, resulting in lack of fusion or cracking. If the gap is too small, the proximity effect will increase, and the welding heat will be too large, causing the weld seam to burn. Or the weld seam forms deep pits after extrusion and rolling, which affects the surface quality of the weld seam.

2. Welding temperature control of welded pipe

The welding temperature is mainly affected by the high-frequency eddy current thermal power. For low carbon steel, the welding temperature is controlled at 1250~1460°C, which can meet the penetration requirements of the pipe wall thickness of 3~5mm. In addition, the welding temperature can also be achieved by adjusting the welding speed. When the input heat is insufficient, the heated weld edge cannot reach the welding temperature, and the metal structure remains solid, forming incomplete fusion or incomplete penetration. When the input heat is insufficient, the heated weld edge exceeds the welding temperature, resulting in overburning or molten droplets, which cause the weld to form a molten hole.

3. Control of extrusion force

After the two edges of the tube blank are heated to the welding temperature, under the extrusion of the extrusion roller, the common metal grains are formed to penetrate and crystallize each other, and finally form a firm weld. If the extrusion force is too small, the number of common crystals formed will be small, the strength of the weld metal will decrease, and cracks will occur after being stressed. If the extrusion force is too large, the metal in the molten state will be squeezed out of the weld, which not only reduces the strength of the weld, but also produces a large number of internal and external burrs, and even causes defects such as weld laps.

4. Regulation of the position of the high-frequency induction coil

The high-frequency induction coil should be as close as possible to the squeeze roller position. If the induction coil is far away from the extrusion roller, the effective heating time will be longer, the heat-affected zone will be wider, and the weld strength will decrease. On the contrary, the edge of the weld seam is insufficiently heated, and the molding is poor after extrusion

5. Weld scars will be produced after welding and extrusion, which need to be removed. The removal method is to fix the tool on the frame, and scrape the weld scars flat by the rapid movement of the welded pipe. The burrs inside the welded pipe are generally not removed.

The products shipped this time were 4140 alloy seamless pipe, 630mm large outer diameter and thick wall thickness seamless steel pipe. The cooperation orders came from regular Indian customers who have cooperated with us for many years. Due to the repeated epidemic in India, the order was delayed. The customer restarted the project after nearly two months of delay. Finally, the contract was officially signed with our company at the end of September. At this time, it coincided with National Day holiday. Both production and space booking gave us challenges.

The market demand for special steel grades is small, and the inventory is mainly conventional products, so special steel grades generally need customized production, and the production cycle is long. The production cycle, which negotiated with customers before, also leads to extremely tight construction period due to delayed procurement. Customers urgently turned to us and hoped that our company would make every effort to coordinate and deliver goods on schedule. The needs of customers was our mission. Xinyue immediately prepared to establish a special team. In the next process, all departments worked together to arrange the most skilled production force, urgently book space and kept the closest communication with customers from time to time. After carrying out a series of pre plans and countermeasures, and finally with the full cooperation of business, documents, procurement and logistics departments, We shortened the preparation time of nearly two weeks and successfully shipped this batch of goods in early October.

No matter the size of the order, we are eager to meet the needs of customers and think about the needs of customers. Xinyue always adheres to the business philosophy of "taking customers as the center" and will do a good job in every order!

Installation points of stainless steel elbow

 1. Before installation, carefully check the various standards of the stainless steel elbow, whether the diameter meets the requirements for use, eliminate the defects caused by the transportation process, eliminate the dirt on the stainless steel elbow, and make preparations before installation.

2. When installing, the stainless steel elbow can be directly installed on the pipeline according to the connection method, and installed according to the position of use. Under normal circumstances, it can be installed at any position in the pipeline, but it needs to be easy to operate and maintain. Note that the medium flow direction of the cut-off stainless steel elbow should be below the vertical valve disc, and the stainless steel elbow can only be installed horizontally.

3. When installing the stainless steel elbow, pay attention to the tightness to prevent leakage and affect the normal operation of the pipeline. The bolts of the packing gland of the stainless steel elbow valve should be tightened evenly, and should not be pressed into a crooked state, so as not to bruise and hinder the movement of the valve stem or cause leakage.

4. When using stainless steel elbow ball valves, globe valves, and gate valves, they are only fully open or fully closed and are not allowed to adjust the flow rate, to avoid erosion of the sealing surface and accelerated wear. There is an inverted sealing device inside the gate valve and the upper thread stop valve, and the hand wheel is turned to the upper position and tightened to prevent the medium from leaking from the packing.

5. Handwheels should be used for stainless steel elbows. Do not use levers or other tools to avoid damage to the valve parts. Turn the handwheel clockwise to close, and vice versa to open.
