The wooden door products in the building materials city are dazzling, which makes us have more space when purchasing, but how can we choose the wooden door that we like? Here we recommend a few tips for reference. First, look at the style and color. The purpose of decorating the house is to create a warm and harmonious living environment, so the first thing to consider when choosing a wooden door is the harmony of the style and color of the wooden door. The decorative style is smooth and clean, and the choice is generous and simple; the lively and bright, we choose the light and elegant to match; the classical ease is decorated with thick and elegant... In short, it is recommended to choose the style to meet. Second, rely on color. Good color matching is the key element of the dyeing room, so after we have determined the style, the second thing to consider is the color of the wooden door and the color of the room. The color matching of the room is basically similar to the chromaticity. The contrast factor is added. We can first divide the color and darkness of the living room, which can be divided into three major colors; wall, floor and furniture soft decoration. Basically, it is enough to keep these three colors, not too much. The color of the wooden door can be considered close to the furniture color, such as the ground is a dark floor wall with white and purple-brown wooden doors. The contrast of the environment and the harmony of the environment. If you don't have much confidence or do not recommend it under the guidance of professionals, don't always think about the comparison. In fact, the environment has been compared. You just need to find the color of the door. Close to the ground, or the wall or furniture, and then distinguish the details, such as the texture of the wooden door and the wood grain on the ground. As for which color to rely on, it should be measured according to the actual situation. Third, feel the touch. After considering the style and color, it is followed by the process and quality of the product. It is unlikely that we will go to the factory to see how he is processed. The quality of the product can only be assessed by simple visual inspection. Here I teach you two words: hand touch and side light. Hand rubbing the door, panel, corner of the door, requires no scratch, soft and delicate, and then stand on the side of the door to see if there is any uneven wave on the painted surface of the door. Basically, you can know whether the work is qualified by these two. 4. Inspection materials and relevant qualification certificates of the manufacturers. But we can't say that we can buy back the wooden doors that are satisfactory and reliable. What kind of materials are used in the wooden doors? Is it environmental protection? Here we can test through three aspects; First, try to choose manufacturers with good brand reputation, recently China The Wood Door Professional Committee of the Timber Circulation Association held a wooden door industry conference in Beijing. The conference selected the top 30 Chinese wooden door enterprises through rigorous research and investigation. These manufacturers are more standardized on the scale of product quality and service system. For example, Dynasty Wooden Door has won a large number of high-end consumer groups with its elegant style and strict environmental protection materials. Second, through the inspection of the relevant qualifications of the manufacturers to compare the relevant industry standards is complete and true, to measure what its product structure is. Third, before installation, pay attention to the internal materials by looking at the door lock hole, and carry out the final check. In addition, the price is also an aspect of measuring quality. It is impossible to be too cheap. Every product has its own cost. The low price with its cost limit is doubtful. For example, the production cost of superior wooden doors should be About 2,000 yuan, if the merchant quotes 1,500 yuan, then there must be a problem. In short, the purchase of wooden doors to follow the above steps, will avoid the misunderstanding of being led by the merchants. Flange is an essential part of pipeline connection, according to the standard is divided into JIS BS DIN ANSI Italian standard. Flange standard is widely used, 10kgs and 16kgs, pressure carbon steel flange, is the most conventional, the most popular, and Commonly used flanges. Standard Flange,Metal Flange,Alloy Steel Flanges,Steel Flange Inner Mongolia Overseas.Trade co.,LTD , https://www.flangevalvejoint.com
The biggest use of flanges is as a way to connect pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes. Reduced engineering costs.
Weld the flange and the pipeline evenly, and then fasten the connection with bolts to effectively connect the pipeline, valve, pump and other equipment accessories, so that the whole pipeline is integrated and starts to work normally.
It is the most widely used pipe fittings in the piping system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding, air conditioning and other departments.
Type of flange:
According to the shape can be divided into: FF flange, RF flange, BLIND flange, SLIP-ON flange, Welding NecK
Flange, Threaded Flange, SocketWeld Flange.
According to the pressure can be divided into: PN16. PN10. PN25, PN40, PN60, PN100,
According to the process, it can be divided into: forged flange, cast flange, steel plate flange
According to the material can be divided into: carbon steel flange, stainless steel flange, alloy steel flange
Flange production process:
1) a: Forged flange
Saw billets of different specifications and models into flange blanks, add them to a reverberatory furnace and heat to 1000 degrees to take out, and then forge the flange blanks into ring flanges by forging machines such as forging presses and air hammers, b: steel plate flanges
Put the steel plate into the punching machine, put it into the corresponding mold, and directly punch it into a ring flange blank.
c: cast flange
Put the low carbon steel standard scrap into the intermediate frequency furnace and heat it to 1200-1500, pour it into the mold
The type is a ring flange blank.
2) The formed ring flange blank is processed into a ring flange on a CNC machine tool according to the drawing, and then the flange is drilled with a CNC drilling machine according to the drawing requirements, and the finished product is completed.
3) For the finished flange product, the thickness, hole diameter, center distance, inner and outer diameter of the flange shall be inspected according to the drawing requirements.
4) Type the flanges that have passed the inspection on the end face of the flange according to the customer's requirements, and do anti-rust treatment to the flange according to the customer's requirements, 1: paint, 2: anti-rust oil, 3: galvanized, and then install it. In wooden box for shipment.
