Ινκολόι 825 Σωλήνωση από ανοξείδωτο χάλυβα

Baosheng Precision Tube provides a wide range of tubular product forms and materials mainly for the oil & gas sector. Our products have been successfully used in some of the most aggressive subsea and downhole conditions and we have a long proven track record of supplying products that meet the strict quality requirements of the Oil & Gas and geothermal energy sectors.

Improvements in the technology for the enhanced exploitation of oil and gas fields has increasingly required the use of long continuous lengths of stainless steel and nickel alloy tubulars for hydraulic control, Όργανα, χημική έγχυση, Εφαρμογές ελέγχου ομφάλιου και ροής. Τα οφέλη αυτής της σωληνωτής τεχνολογίας έχουν οδηγήσει σε μειωμένο λειτουργικό κόστος, improved recovery methods and reduced capital expenditure by connecting downhole valves and chemical injection with remote and satellite wells to a fixed or floating central operating platform.

Redrawing process of welded tubes

Long lengths can be made by seam welding formed strip but such tubing has OD & ID discontinuity and may suffer from local problems of mechanical strength or corrosion. A welded & sunk tube improves these aspects and has been proven reliable in service over several decades for offshore applications. Although more expensive than welded only tubing, the welded and redrawn tube is still relatively inexpensive compared to seamless.

Seamless tubing has cross sectional uniformity however, it is the most expensive method of manufacture and has a limitation in the continuous length that can be produced between joints. For a slight premium over the welded & sunk price, tubing can be produced by the welded & floating plug drawn process which results in a product of similar appearance to seamless but with the significant advantage of much longer continuous lengths and greatly reduced costs.
