The above is the purchase order details, and the product requirements are clearly for 90 degree and 180 degree ASME B16.9 carbon steel elbow. Although the specifications are conventional, the customer's inspection requirements are extremely strict - they require cutting the elbow along the center line, measuring each internal parameter one by one, and providing detailed inspection photos. This is undoubtedly a test of the intrinsic quality of the product. To ensure that customer requirements are met, we have produced several samples in advance and strictly processed them according to the inspection methods specified by the customer.
During the cutting process, we are careful to avoid affecting the measurement accuracy due to improper operation; In the measurement process, technicians use high-precision detection tools to accurately measure key internal parameters such as wall thickness uniformity, weld quality, and curvature radius of the elbow, and record data synchronously; When taking photos, we present the internal state and measurement details of the product clearly from multiple angles, ensuring that customers can intuitively understand the product quality. After receiving the sample inspection photos and data reports, the customer highly recognized the precision manufacturing and stable quality of the product.
Inspection of 180 Degree Elbow
Due to the small size but large quantity of elbows in the order, protection during transportation becomes crucial. To ensure that the goods are not damaged during long-distance transportation (especially cross-border transportation), we have customized wooden box packaging solutions for our customers. The wooden box is made of sturdy materials, and the interior is reasonably divided according to the shape and quantity of bends. Each bend has independent buffer protection, effectively avoiding collisions and compression during transportation.
Package of ASME B16.9 Carbon Steel Elbow
We track logistics information throughout the entire process from product production, inspection, packaging to final shipment, and provide timely feedback to customers on the status of goods. After receiving the goods smoothly, the customer once again expressed their appreciation for our professional service.
ASME B16.9 carbon steel elbow is a butt welded elbow made of carbon steel material manufactured according to the American standard ASME B16.9. It is widely used in industrial fields, including petroleum, natural gas, chemical, power and other industries.
1. According to the bending radius, it can be divided into long radius elbows (LR ELBOW) and short radius elbows (SR ELBOW).
2. According to the bending angle, it can be divided into 45 degree elbows, 90 degree elbows, and 180 degree elbows.
3. According to the production method, it can be divided into seamless elbows and straight seam elbows.
