Syarat Test
Tes hidrolik
Tes hidrolik kudu ditindakake kanggo pipa baja siji-siji. Tekanan test maksimum yaiku 20 MPa. Ing meksa test, wektu stabil ora bakal kurang saka 10 s, lan bocor saka pipe baja ora diijini.
Tes flattening
Tes flattening kudu ditindakake kanggo pipa baja kanthi diameter njaba luwih saka 22 mm
Tes flaring
Baja struktural karbon berkualitas tinggi lan pipa baja tahan karat (tahan panas) kanthi diameter njaba ora luwih saka 76 mm lan kekandelan tembok ora luwih saka 8 mm kudu diuji. Tes flaring kudu ditindakake ing suhu kamar. Ing diameteripun njaba flaring rate saka sampel sawise inti ndhuwur taper punika 60% saka flaring bakal ketemu syarat Tabel 7. Ora retak utawa retak diijini ing sampel sawise flaring. Miturut syarat panjaluk lan kacathet ing kontrak, baja struktural campuran uga bisa digunakake kanggo tes ngembangake.
Teste nondestruktif
Pipa baja kudu tundhuk deteksi cacat ultrasonik siji-siji miturut pranata GB / T 5777-2008. Miturut syarat panjaluk, tes non-ngrusak liyane bisa ditambah sawise negosiasi antarane supplier lan panjaluk lan dituduhake ing kontrak.
Tes korosi intergranular
Tes korosi intergranular kudu ditindakake kanggo pipa baja tahan karat (tahan panas). Cara tes kudu sesuai karo pranata metode Cina E ing GB / T 4334-2008, lan kecenderungan karat intergranular ora diidini sawise tes.
Sawise negosiasi antarane supplier lan panyedhiya, lan kacathet ing kontrak, panjaluk bisa nemtokake cara tes karat liyane.
