Threaded couplings are perhaps the most common and widely used in many industrial sectors from the hydraulics to wine production. They are distinguished by the type of thread (BSP or NPT) whose different norms are such that the helical pitch of the thread does not allow the possibility of cross-threading with each other. They can be made in various materials and used in many situations as low cost connection solutions.
Widely used by many industries, the CAM-LOCK quick coupling system has many advantages. It is made of 2 mating parts, male and female, and requires no tools for locking and unlocking. CAM-LOCK couplings were developed in order to obtain a quick and secure connection between two pipes.
AFNOR (Association Française de Normalisation) is the French association for standardization with the task of governing the national regulatory system and upholding the interests of France in the field of international standardization, promotes the application of the law and develops certification products and services.
Storz is a type of coupling invented by Carl August Guido Storz in 1882. It was also referred to as a “sexless coupling”, i.e. connection without gender, because rather than having one end male threaded and one female threaded, they have identical ends that can be joined together. It was also called free hermaphrodite or bi-directional connection..
DIN is an acronym that stands for the German Institute for Standardization, DIN11851 is the German standard for high-profile fittings for use in the wine, dairy, chemical and pharmaceutical industries, for confectionery and food in general. It comprises of a round slotted nut and a flush fitting lipped seal. The male fitting features an inverted cone face that carries the seal, while the liner is similarly conical in section.
The SMS (Swedish metric standard) system is designed for applications that do not require regular disassembly of hoses. It consists of an internally threaded ring that has a captive seal designed to provide a smooth, crevice free internal bore. The tightness of this fitting system is guaranteed by the captive seal inserted into the groove on the female which is pressed by the male mating part.
Quick coupling system, safe and versatile for food processing and for distribution lines in pharmaceutical plants. Clamp fittings are widely used in CIP processes for their ease of assembly and disassembly. There is no need for any tools to do this, you need only hands.
The connection more widespread in the wine producing sector is the one obtained through stainless steel fittings and clamps called Garolla. Very similar in concept to other types of clamp fittings, it is composed of two identical unions, each of which may have a corrugated end (to be inserted in the terminal part of the pipe and tightened by a clamp through this metal) and the opposite end flared and curved edges.
MANN TEK quick couplings are also referred to as called “dry” because the system of connection and disconnection is such that you do not lose a single drop of the product conveyed. They are specially designed for quick coupling and without leakage. The secret is in the engineering system which provides a valve that opens when the lever is fully engaged and the parties are permanently coupled. And, in the models with this feature when, for whatever reason, the lever disengages, it acts as a safety valve, venting the pressure in the joint and halting the flow.
