The Packaging Method and Main Parameters of Tubing and Casing

After the tubing, casing pipe and line pipe are produced, the surface is usually sprayed with anti-corrosion paint (Varnish, coating), and the outer surface of the pipe is sprayed with a striking mark according to the API standard, indicating the product manufacturer and the manufacturer’s ISO certificate number , API logo, API certificate number, nominal diameter, nominal weight, steel grade, length, forming method, water pressure size, furnace number, batch number, tube number and identification of customer special needs, such as shipping marks. The threads of the oil casing should be protected with special thread anti-rust grease. Each pipe should be buckled with steel-plastic protective caps at both ends to protect the thread or chamfer.

For petroleum special pipes, steel belts are generally used for packaging, and the weight of each bundle should not exceed 2.5 tons, which is convenient for loading and unloading. A waterproof label is usually attached to each bundle, stating the manufacturer, product specifications, quantity and remarks.

The main parameters include: product name, quantity, outer diameter, wall thickness, steel grade, pipe body production method, reference standard, length range, for example:
