Process: Pipework


Pipe work (tube bending) is a method to bend tubes. It is usually carried out in a pipe and tube bender.

The intention of tube bending is to form a tube that fits a certain component or product. The machine, a pipe bender, puts the pipe in between a clamper and a die and presses until a bend is created. The bend can be a U-bend, an elbow bend, a two or three dimensional bend. Two dimensional bends are created in one plane, meanwhile a three dimensional bend is outside that plane, which means it is more complex.

There are several common techniques for bending pipes. Which type that is suitable depends on the component's requirements, the bend's radius and the pipe's dimensions and the material type. A common kind of bending is press bending. Then a press with a die pushes against the pipe, forming a bend. Press bending is primarily common when the pipe's cross section does not have to be identical for every component. Another kind of pipe bending is done in a rotary draw bender, which uses dies with a constant radius. Instead the bend is determined by how close the tools move towards one another. A third kind of bending, heat-induction, is for large pipes. Before bending large pipes, the section that is to be bent is heated before the bending process begins. In addition to these methods, there are some less common ways to bend pipes.

Often the bending creates irregular shapes of the cross section. This can be prevented by filling the pipe with sand or a powerful spring, which prevents the deformation.

Pipework projects for quote

  1. Drawings count: 0


    This company has posted this request for information as they are looking for a supplier to place an order with for the cutting of free-issue pipe. The client has advised that the pipe lengths will need to be collected by the chosen supplier, with delivery of the cut pipe ideally required by 30th October. This could lead to repeat business going forward once a relationship is established with the right supplier. Pricing and reliable collection and delivery are all important considerations within this enquiry. **Due to the current health climate, we ask that you only submit a quotation for this project if you are in a position to fulfil the requirement. Please also be mindful that there may be a delay in buyer response due to widespread remote working.**

    This client, a designer of bespoke interiors, currently seeks a supplier with the capabilities to produce the attached drawings of an industrial dining table and wall shelving units. The main concern the buyer has with regards to these frames is that they may end up being too heavy, making them difficult to fit on-site. The buyer would appreciate suggestions of any frame system of a lighter weight, or thinner pipe thickness, that would still have a similar look to the drawings provided. As well as having an immediate order to place, the client has advised that similar work will be made available moving forward. **Due to the current health climate, we ask that you only submit a quotation for this project if you are in a position to fulfil the requirement. Please also be mindful that there may be a delay in buyer response due to widespread remote working.**

  3. Drawings count: 1


    Suppliers with immediate capacity are sought in order to undertake production of the attached design. The client - a company who operates within the construction sector and outsources £100,000 worth of fabrication work every year - has an urgent order to place and therefore requests prompt responses from interested suppliers. Please note that delivery is required within 1-2 weeks of order placement.

  4. Drawings count: 3


    The manufacture of "stat pockets" is required for use in a range of hot water storage systems.This enquiry will be used in order to fulfill a requirement for the Oil/chemical sector. The buyer is looking to work with a supplier that can offer good value, with quotes also favored from those who have ISO 9001 accreditation in place. Suppliers are asked to make contact with the buyer directly to discuss the opportunity. There will be an order to place with the chosen supplier with ongoing orders to follow.
