Industrial, chemical and effluent process pipes # 1974 Southampton
Due to the increasing production of metallurgical products — applicable to innumerable fabrications — suitable plant for the removal of the scale adhering to hot rolled goods thus became necessary in order to produce a surface rendering possible a further treatment of the pre-material.
A new phase of development in the field of construction of pickling plant for
- wires, etc.
thus started about 30 years ago.
The high qualities demanded for by the customers and the production increases necessary to meet the demand on the market required a complete redesign of the existing simple pickling plant. It was found in this phase of development that media such as hydrochloric acid, sulphuric acid and nitric acid, heated up to 90— 100°C accelerate the pickling process considerably.

Despite recent efforts in promoting the utilization of recycled polymeric materials for more diverse and more advanced applications, there are still significant knowledge gaps with regards to the applicability of certain recyclate types for specific “re-use” purposes. When it comes to pipe applications, for instance,...

In the present paper, a highly effective test and characterization concept for polymer recyclate materials is proposed and validated. Based on the proposed methods, a study was carried out to investigate the potential of in-plant and post-use PE recyclates from various applications to be utilized in PE recyclate...

Plastics materials are rapidly replacing copper pipes and fittings in domestic plumbing and heating systems throughout the world. Over the last 20 years pressure pipe systems made from Polypropylene Random Copolymers (PP-R) have been widely adopted by the plumbing and heating industry in numerous countries around the...
