“NPA” is a leading manufacturer for centrifugally cast tubes and static/precision castings of heat resistant alloys for ethylene cracking furnaces, reformer furnace tubes, CAL (Continuous Annealing Lines) & CGL (Continuous Galvanizing Lines) furnace rollers and radiant tubes, glass lehr rollers and heat/wear resistant castings. NPA is a private share holding company founded by professional engineers and experts. Most of them have been in the heat resistant furnace roller and tube industry for about 30 years and have made an important contribution to the huge improvement of local ethylene cracking furnaces, hydrogen reformer furnaces, steel strip continuous annealing lines, continuous galvanizing and float glass lines. The majority of the management and technicians has more than 15 years experience with manufacturing heat resistant centrifugal castings and static/precisions castings, cumulating rich experience and patented technology and knowhow. NPA is now one of the biggest and most advanced companies in China with high level technology, modern machinery and quality awareness, targeting to provide best turn-key solutions for international customers. NPA has very well equipped R&D capacities, working closely and extensively with renowned scientific research institutes and colleges to develop new product and materials. NPA has established complete quality assurance system including ISO 9001, environment ISO 14001 and occupational health and safety OHSAS18001 (GB/T28001). For all difficulty levels of welding stainless, heat-resistant and high alloy steels and castings, GS-PERAMET has successfully become an expert for challenging welding jobs on German and European market. Orders placed by well-known energy-generating companies, steel industry, petrochemical contractors as well as by chemical and food companies, prove the general high acceptance of GS-PERAMET’s performance. In workshops, welders and pipe fitters produce “X-Ray Quality” seams in accordance with the relevant regulations (e.g. for RT in accordance with AD regulations, otherwise in accordance with DIN EN 12517-1 of all material groups 5, 6, 8, 36, 43 and 45). nspection and quality assurance of the welding work is carried out by our welding coordinators, engineers and specialists (SFI and SFM). GS-PERAMET’s quality guarantee is supervised by permanent inspections of the seams (VT, PT, MT, UT and RT).

GS-PERAMET’s experts dispose about following approvals / certificates:

·   ISO 9001, AD2000 HP 0, DIN 3834-2

·   Welding procedure qualifications for the processing of all current material groups, in particular the material groups 5, 6, 8, 36, 43 and 45.

·   Manufacturer’s qualification for welding steel structures according to DIN 18800-7 in accordance with Water Resources Law.







In cracking furnaces raw materials such as ethane, liquefied petroleum gas (LPG), naphtha, atmospheric gas oil (AGO) and hydrocracker residue are converted into ethylene and valuable by-products. Modern cracking furnaces have capacities of over 250,000 MTA of ethylene and fired duties of over 100 MW per furnace in short residence times. Operating temperatures even exceed 1000-1150° C. Thermal cracking processes need radiant coil systems - essentially consisting of high-alloy tube assemblies, fittings or bent tubes - all welded, gas-tight constructions.

Complete radiant coil systems, tube assemblies, fittings as spare parts are regularly changed in existing crackers and installed in new capacities. Global demand of ethylene is continuously growing.
