Stainless steel butt welded tee is a three-way junction in pipeline systems - splitting a main pipeline into two branches or merging two tributaries into one, all welded to the pipeline with this sturdy and durable connector. The manufacturing of stainless steel butt welded tees specifically solves the problem of "pipe separation". What does it mean? Chemical plants use it [...]

Stainless steel seamless elbows exhibit unique aesthetic value in the field of decoration due to their smooth surface, metallic texture, and plasticity. In terms of architectural exterior decoration, stainless steel seamless elbows can be used as skeleton connectors for curved curtain walls, forming streamlined support frames through precise bending. After mirror polishing, the surface is combined with glass to create [...]

Stainless steel seamless elbow is a component used in pipeline systems to allow liquids or gases to turn steadily in the pipeline. The key process for manufacturing it is steel pipe hot pressing. First, the stainless steel pipe is placed on the mold, like making a ceramic blank. Then, the steel pipe is softened at a high temperature of 1200 [...]

The necessary steps for repairing chloride ion corrosion leakage points in stainless steel seamless elbows are threefold: ① Polish the leakage point until the metal color is exposed; ② Apply specialized chloride ion anti-corrosion coating (such as KNM22 type) to block corrosion; ③ The outer layer is wrapped and welded with 316L material sleeves. Do not directly repair welding without [...]

The dimensional instability of stainless steel seamless elbows after cold drawing process is mainly related to four factors: material, process, mold, and stress. Let's first talk about the manifestations of dimensional instability: fluctuations in outer diameter, uneven wall thickness, bending deformation, etc. 1. Magnification of material defects themselves Segregation and inclusions: Steel pipe billets exhibit sulfur phosphorus segregation or central [...]

The main reason for the occurrence of bending wrinkles in stainless steel seamless elbows is the loss of process control. There are two triggers: 1. Excessive bending angle: The wrinkling rate of a 90 ° bend is 50% higher than that of a 45 ° bend (due to excessive stretching of the outer material during bending). 2. Mold deviation: Expansion [...]
