Description

Coupling is a kind of fitting commonly used in industrial pipeline connection, also called direct head. Coupling is a short pipe used to connect two pipes. Because of its convenient use, it is widely used in civil construction, industry, agriculture and other fields.According to its manufacturing process, the Coupling can be divided into forging and casting.

Casting refers to melting the ingot and pouring it into a fixed Coupling model, then cooling it.The bell and spigot Coupling is a pipe connector machined after the forging of round steel or ingot. Its connection form is socket welding. The steel pipe is inserted into the socket for welding. The main manufacturing standards are ANSI / ASME B16.11 and GB / T 14383-2008.

The variety of collar includes double socket collar and single socket collar. Among them, double socket Coupling can be divided into equal diameter and different diameter.Double socket Coupling with different diameter can be divided into concentric and eccentric.

Specification

Standard: ASMEB16.11,GB/T14383-2008

Connection method:Socket welding

Specifications: DN6~DN100

Characteristic

Long service life. Under the condition of rated temperature and pressure, the Coupling can be used safely for more than 50 years.Excellent corrosion resistance. The Coupling can resist the corrosion of most chemicals, and can withstand the corrosion of high concentration acid and alkali with pH value ranging from 1 to 14 in a large range.

High stiffness. Due to the addition of glass fiber reinforced materials, the Coupling is not easy to deform.Heat and insulation. The maximum operating temperature of the energy-saving Coupling is 95 ℃, and the thermal conductivity of the product is only 1 / 200 of that of the steel pipe, so it has better thermal insulation performance.

Application

Stainless steel socket welding Couplings are made of 304, 304L, 316, 316L and other stainless steel materials.Stainless steel socket welding Couplings are corrosion-resistant, high temperature resistant, high pressure resistant, sanitary and non-toxic, recyclable and suitable for corrosive liquid transportation (such as acid and alkali liquid) and municipal water supply and drainage system.

The stainless steel socket welding Coupling has excellent anti impact strength and tensile strength, light weight and convenient installation and maintenance. Coupling is widely used in chemical industry, chemical fiber, dye, water supply and drainage, food, medicine, sewage treatment, electrolysis and other industries because of its unique performance.
