Stainless steel reducers are safe, reliable, hygienic, environmentally friendly, and economically applicable. The thinning of pipelines and the successful development of new reliable, simple, and convenient connection methods make them have more advantages that cannot be replaced by other pipes. Their application in engineering will become more and more widespread, and their prospects are promising.

There are various connection methods for stainless steel pipes, including compression type, compression type, union type, push type, push thread type, socket welding type, union flange connection, welding type, and a derivative series of connection methods combining welding and traditional connection. These connection methods have different applicability depending on their principles, but most of them are easy to install, sturdy, and reliable. The sealing rings or gaskets used for the connection are mostly made of silicone rubber, nitrile rubber, and EPDM rubber that meet national standards, eliminating users' worries.

The materials of reducers include stainless steel reducers, alloy steel reducers, reducer carbon steel reducers, reducer 20 steel q234q345, etc. Attention should be paid to the large and small heads, which are also suitable for pipeline diameter reduction in the environmental protection and dust removal industry. They are generally made of steel plates rolled, cut, and welded, with varying pipe diameters. The materials used are generally hot-rolled coils, which are very useful and can save costs.

The quality of the reducer should comply with the current national standards GB/T 12459-2005 for seamless welded steel fittings and GB/T13401-2005 for welded steel fittings. The roundness of the reducer should not exceed 1% of the corresponding end outer diameter, and the allowable deviation is ± 3mm. The allowable deviation of the reducer size should comply with the provisions of Table 4.2.2-3. The material of the reducer shall comply with SY/T5037, GB/T9711, GB/T8163, American standard ASTM A106/A53 GRB, API 5L, APT5CT, ASTM A105, ASTM A234, ASTM A106, DIN German standards and customer requirements standards.
