Product Description

Product Description

ASTM A312 TP304L Stainless Steel Seamless Pipe for Petrochemical Application

The grade 304L can be used in mild chemicals with less acidity and less oxidation and reduction capacity. Food and beverages industries often deal with mild acids like carbonic acids, citric acid and tartaric acids. These are found in food items and are mild acids that do not corrode the 304L Pipe. The material has 18% chromium and 8% nickel along with other additions but with less carbon than the ordinary SS304 Pipe material.
 
304L is a variant of 304 stainless steel with lower carbon content and is used where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, and the precipitation of carbides may cause stainless steel to produce intergranular corrosion (welding erosion) in certain environments.
304L stainless steel has poor forging performance and difficult deformation.
Due to work hardening. So that the amount of deformation in the process of mandrel drawing can not be too large. And the heat loss is large. Therefore, it must be formed under many fires. If the high temperature holding stage is not handled well, it will cause coarse crystals.

  1. All of our stainless steel seamless pipe & tubes are packaged as per international standard to prevent any possible damage or loss. By default, we will use thick woven plastic bag to bundle the finished pipes together in batches.
  2. For some special pipes & tubes that are vulnerable to dirt, scratches, stress or rough handling, we will suggest wooden case for protection. Kindly note, wooden case can incur extra cost, not only its own cost, but also the increased freight cost, which is especially true for air transportation.
  3. For enhanced customer experience, we also provide dedicated package as per your special requirements.
