Storage of seamless steel pipes

In order to better serve our customers and improve the quality of our products, we have made basic requirements for the storage of seamless tubes produced by our company.

Storage of seamless steel pipes

1) The site or warehouse for the storage of seamless steel pipes should be clean and well-drained, far away from factories and mines that produce harmful gases or dust. Weeds and all debris should be removed on the field, and the steel should be kept clean;

2) Do not stack with acid, alkali, salt, cement and other materials that are corrosive to seamless steel pipes in the warehouse. Different types of seamless steel pipes should be stacked separately to prevent confusion and contact corrosion;

3) Seamless tubes shall not be directly stacked on the ground, steel plate or cement floor. In order to avoid dampness and pollution of boiler tubes, the distance of the first layer Seamless tubes (or bundles) from the ground is not less than 0.20m.

4) The rack or stack should be arranged neatly, and the rack or stack should have a clear marking number. Seamless tubes shall be placed on designated racks or stacks according to the number (batch number), type, specification and thread type of the furnace. Seamlesstubes with the same specification (or similar) and the same thread type but different furnace numbers are not allowed to be stored in the same rack or stack.

5) In order to prevent bending or thread damage of seamless tubes, seamless tubes (or tube bundles) should be placed on sleepers with proper spacing and on the same horizontal plane (small square steel components with inner steel and outer plastic can be used instead of sleepers, but it is necessary to ensure the integrity of outer plastic, metal can not be exposed, the same as below), and ensure the alignment of one end of seamless tubes. Separation sleepers should be placed between casing and tubing (including casing and tubing bundles) layers (excluding code square stamping), at least two in each layer, and the sleepers should be placed vertically on the seamless tube and aligned up and down. If the seamless tube is stacked in the code layer (including the code square stomp) without the material rack, the wooden wedge should be properly placed or other methods should be adopted to prevent the rolling of the seamless tube.

6) Seamless tubes after cold rolling, cold drawing or bright annealing are not allowed to be stored in the open air. If the storage conditions are limited, appropriate protective measures should be taken to avoid corrosion of rainwater, snow, fog and a large number of dust pollution of boiler tubes when open storage is needed.
