Hydroforming equipment uses fluid pressure to form tubular ferrous or nonferrous materials to the shape of a die. This processing form allows for severe shape deformation and generally produces strong parts of uniform thickness.
In mandrel bending, also called rotary-draw bending, a mandrel is inserted and positioned into the pipe during bending. As the pipe is bent, the mandrel is pulled through the pipe so that the shape is maintained and the bends are not deformed.
Ram bending, also called pressure bending, uses a die and hydraulic ram for bending. The tube is placed in a die and the hydraulic ram, which contains the other half of the die presses into the tube to push it around the radius.
Roll bending uses three powered rollers in a triangular arrangement. The center roller applies downward pressure to bend the tube. The higher the pressure, the sharper the radius. Roll bending differs from mandrel bending in that the inside of the tube is not supported.
Tube or pipe is heated prior to bending. In heat-induction pipe bending, an induction coil is placed around the pipe to be bent. This section of the pipe is heated to temperatures from 800 °F to 2200 °F. A bending force is then applied to the tube as it slowly passes through the induction coil. Other heat methods are also used.
Sand packing and hot-slab bending is an old process where the pipe is packed with sand, the ends capped, and the tube or pipe heated. The sand minimizes collapse and ovality of the pipe. The temperature and method of heating is may vary depending on the material. The pipe is then removed from the heat source and bent, with one end secured to a bending slab. A variation of this process is used on PVC as well as steel tubes and pipes.

There are two different types of stainless steel tubing, hypodermic gage and fractional tubing. Fractional tubing is made to common fractional sizes (such as 1/4" OD) and specified in terms of the outside diameter and wall thickness. Hypodermic, or needle tubing is specified by gage size, which is determined by the OD and wall thickness of the tube.
Supplier can bend tubing with a very small wall thickness.

A bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
Brass comes with good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability.
A commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content.
Copper tubing may be cut and formed readily and is often used in gas or refrigerant applications. Copper is a common reddish metallic element that is ductile and malleable and is one of the best conductors of heat and electricity.
Any of numerous organic, synthetic, or processed materials that are mostly thermoplastic or thermosetting polymers of high molecular weight and that can be made into objects, films, or filaments.
Polyvinyl Chloride (PVC) is a widely used material that has good flexibility, smooth surface, and nontoxic qualities. Some grades are used in food and chemical processes due to the inert nature of PVC. Brand names include: ACP® and Dural® (Alpha Gary), Geon® (Geon), Benvic® (Solvay), Flexalloy® (Teknor Apex).
An alloy, usually based on nickel, cobalt or iron, developed for high temperature service where relatively severe mechanical stressing is encountered and where high surface stability is frequently required.
Titanium is a hard, lustrous, silvery, element that is relatively abundant in the Earth's crust. It is known for its lightness, strength, and corrosion resistance. For this reason it is used widely in the aerospace industry and the medical fields (e.g., replacement joints). When alloyed with other metals, especially steel, it adds strength and oxidation resistance.

Annealing is a heating and cooling operation, usually with a slow cooling cycle. Annealing may be used to remove stresses, induce softness, and alter ductility, toughness, electrical, magnetic, or other properties.
Polishing, buffing, and belting processes are metal smoothing operations that change the surface appearance of the metal. These operations can be for aesthetic and/or functional purposes.
Supplier has capabilities to produce forms on the end of a tube, such as chamfers, flanges, end reduction, end expansion, doming or rounding, beading, and flaring.
Supplier can provide painting to provide a protective and/or decorative coating. Powder coating is finishing technologies in which dry paint particles are electrostatic ally charged and applied to a smooth surface. Electrostatic attraction holds powder particles on the part surface until heat is added to flow the powder together and cure it. Parts must be electrically conductive. Although powder coating is most widely used on metal parts, recent technological developments have broadened the type of substrates to include glass, special plastics and wood.
Applying a coating, or plating to the surface of a tube or pipe. Examples of plating and coating options include anodizing, galvanizing, zinc plating, copper plating, and nickel plating.
Supplier has capabilities to punch or pierce holes in tube. The two main styles are dimple hole punching and mandrel hole punching. In dimple punching, a dimple is created in the tube during the punching operation. In mandrel punching, a mandrel is placed in the tube during punching to prevent the diameter geometry from being altered.
Swaging forms a tube through a rapid series of hammer blows. Swaging can be used to point, size, reduce, shape, taper, bond or form metal parts, hot or cold. It is an economical process that does not produce any chips, improves grain structure and produces a fine finish.

ISO 9001:2000 sets out the requirements for a company's quality management systems. These standards range from manufacturing to services including design and development, production, installation and servicing.
In 1987, International Standards Organization (ISO) 9000 standards were developed to ensure that companies' products and services have consistent, documented approaches that meet the European community's quality requirements.
ISO 9001 sets out the requirements for an organization whose business processes range all the way from design and development, to production, installation and servicing.
In 1987, International Standards Organization (ISO) 9000 standards were developed to ensure those companies' products and services have consistent, documented approaches that meet the European community's quality requirements.
ISO 9002 is for an organization that does not carry out design and development. It does not include the design control requirements of ISO 9001 - otherwise, its requirements are identical.
ISO 14001 specifies the actual requirements for an environmental management system. It applies to those environmental aspects, over which the organization has control or influence. ISO 14001 was first published in 1996 and is the only ISO 14000 standard against which it is currently possible to be certified by an external certification authority.
QS9000 defines the fundamental quality system expectations of manufacturers for internal and external suppliers of production and service parts and materials. These companies are committed to working with suppliers to ensure customer satisfaction beginning with conformance to quality requirements.
