Acrylonitrile butadiene styrene - Wikipedia

Acrylonitrile butadiene styrene (ABS) (chemical formula (C8H8)x· (C4H6)y· (C3H3N)z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F).[2] ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the

How to Use Pluer''s Tape

The trick to getting pluer''s tape right is to wrap it around the pipe in the proper direction. When the pipe is turned into the fitting, the friction of the mating threads should work to tighten the tape around the pipe, rather than work against it and unravel or ball up the

The nature of polyethylene pipe failure | PlasticsToday

At the microscopic level, there are many inherent stress-concentrating defects within the microstructure of the pipe wall and on appliion of a few MPa of stress, the yield strength of the polymer will be locally exceeded. Micro-yielding blunts these defects and initially stabilizes them.

Plastic pipe, PPRC pipes in factories to human health, considering the value they give does not contain carcinogenic substances that affect human health, Europe''s leading countries and no successful results were obtained in tests it was determined that it did not cause health problems. In the United States, is approved by the health care law.

Plastic collapse analysis of thin-walled pipes based on

Based on a unified yield criterion (UYC), the plastic collapse analysis of thin-walled pipes is conducted in the framework of finite strain. A unified analytical solution for the burst pressure of end-capped defect-free pipes is derived, which is fit for various kinds of …

Importance of Yield Strength & Plastic Deformation to

Importance of Yield Strength & Plastic Deformation to Civil Engineers . When metals are being stressed in tension at relatively low levels, the applied stress is linearly proportional to the induced strain, i.e. elastic deformation. The relationship between the applied stress, s and the strain being induced, e is as follows: s = E e

Introduction of the delta concept for characterising pipe

Hitherto, an effective universal measure that characterises the yield strength change from a plate/coil to a pipe has not been established. This implies that with existing measures, the pipe yield strengths can vary significantly for the same steel grades manufactured by the same groups (or by different groups across different times).

Apparent strain of a pipe at plastic bending buckling state

An expression for apparent strain of a pipe at plastic bending buckling status is proposed in the present paper. The material of the pipe is considered as a rigid-perfectly plastic one, and the cross section of the pipe during the pipe-bending process assumes to be elliptic gradually.
